James Webb has bad news for the largest natural laboratory for rocky planets, but there is still some hope

by

The star TRAPPIST-1 and the seven known planets that surround it are a natural laboratory in which the evolution of rocky planets can be studied. This has led many scientists to focus their attention on them, in search of a possible habitable planet. However, observations made by an international team of astronomers with the help of the James Webb Space Telescope They are not very encouraging. Planets without atmosphere. The James Webb Space Telescope has a very powerful infrared radiation analysis instrument, with which it can analyze the temperature of the planets it observes. These emit infrared radiation whose intensity is proportional to their temperature, so a thermal map can be made. That’s what these astronomers have done. They have initially focused on two of the planets that orbit TRAPPIST-1: TRAPPIST-1a and TRAPPIST-1b. The resulting heat map shows that neither planet has an atmosphere. They may have had it one day, but possibly TRAPPIST-1 itself destroyed it. It is a very uninspiring result for the search for habitable planets in this system. Lights and shadows of TRAPPIST-1. So far seven exoplanets have been discovered orbiting TRAPPIST-1. They are all very close together. In fact, its seven orbits are concentrated in the distance between Mercury and the Sun. What happens is that this red dwarf is less energetic than our Sun, so the temperature would not be as suffocating. All of these planets are rocky, like Earth, and in fact, some are very similar in size. There could be an exoplanet with conditions similar to ours. The problem is that red dwarfs They emit a lot of radiation and energetic flows of particles that could destroy their atmosphere.. And of course, without atmosphere, there is no life. Tidal lock. All planets in the TRAPPIST-1 system are tidally locked. This means that its rotation and translation period around the red dwarf they are synchronized. As a result, there is one side continuously exposed to the star and another on the opposite side. On one side it is always day and on the other it is always night. NASA/JPL-Caltech Extreme temperatures. When a planet is tidally locked, there can be two situations, depending on whether it has an atmosphere or not. When there is an atmosphere, heat flows from the light side to the dark side, so that the entire planet has a stable average temperature. On the other hand, if there is no atmosphere, the dark side can be frozen and the illuminated side can be scorched. In the two exoplanets analyzed by James Webb, it has been seen that temperatures are around 100ºC-200ºC on the illuminated side and -200ºC on the dark side. Therefore, it is confirmed that there is no atmosphere. And now what? Despite this hard blow, there is still hope. The two exoplanets that have been analyzed are not in the star’s habitable zone. This is the distance from it at which the temperature is adequate for the water, if any, to remain in a liquid state. At that exact point there are only TRAPPIST-1e, TRAPPIST-1f and TRAPPIST-1g. Furthermore, the former has a density and size very similar to those of Earth. James Webb has all his attention on this exoplanet right now, to repeat the process. If there were an atmosphere on it, it could still remain on the list of possible habitable planets. It’s still interesting. Despite the first blow, TRAPPIST-1 remains a very interesting system for understand the evolution of rocky planets. The Earth was lucky not to lose its atmosphere; but, beyond those, the evolutions can be similar. Furthermore, we have not yet ruled out that TRAPPIST-1e has an atmosphere. Let’s go step by step.

The length of “a day” on all the planets in the Solar System, explained in a revealing video of just one minute

by

The Universe is full of unknowns for humanity. What’s more, even data that we know ends up being questioned and reformulated, such as: the distances between planets in the solar system. In fact, as a millennial, when I was a child I learned all the planets at once and then I had to forget about Pluto. However, a reasonably solid and most interesting piece of information is How long is a day on a planet in the Solar System?information that on Earth is approximately 24 hours (23 hours and 56 minutes, specifically). This duration is due to the average time it takes our planet to complete a rotation on its own axis, although translation has an influence. Furthermore, it has evolved historically due to the gravitational pull of the Moon. Thus, and in general terms, we can establish that to estimate this duration, factors influence its radius, its orbit and also interactions with other celestial bodies. The reality is that we are facing a non-intuitive pattern with results that defy logic. To solve the question numerically, the popular science channel The Brain Maze has a great video the most agile and visual to clear our doubts with the figures in just one minute: Now we know how much, but it is even more interesting to understand why. As a summary, there are certain general rules that are met: paradoxically the largest planets are those that rotate the fastest and those closest to the Sun have suffered the effects of gravitational tides in such a way that they have slowed down to almost a stop. Although we already told you that there are quite a few anomalies. The counterintuitive pattern for determining how long a day is The Sun and the planets of the solar system. The sizes are to scale, but the distances are not. By Edits by Pepedavila.

When the Solar System formed, these early planets accumulated gas and dust with angular momentum. The gas giants captured so much material in a short time that they were able to preserve almost all of that original angular momentum. They go without brakes and it shows: it takes Jupiter less than 10 hours to make a complete revolution on itself, despite the fact that compared to Earth, it is more than 300 times its mass and 11 times larger. With Saturn this also applies, but for Uranus and Neptune the explanation is incomplete: the ice giants also spin fast for the same reason, but their history is much more eventful, either due to collisions or disturbances in the early days. On Mercury and Venus the days become eternal. The rocky planets close to the Sun found a brake in the tides. Mercury is so close to the star that its gravity has dissipated its original rotation over time. If you were on the surface of Mercury looking at the Sun, you would see it stop, move backwards, and move forward again: it is the effect of its elliptical orbit and its slow rotation, compared to its orbital speed. In fact, even has a double dawn in some parts of the planet. Venus is also slowed down by the sun’s gravity, but it also rotates in the opposite direction. Because? Good question, for you, for me and for science in general: it remains a mystery, although there are hypotheses. A curiosity to reinforce the rarities of Venus: a day lasts longer than its own year, it takes 243 Earth days to rotate on itself and only 225 to complete its orbit around the Sun. By the way, the fact that a day on Mars and on Earth lasts practically the same is, according to science, almost certainly a coincidence. This similarity and other factors have fueled for decades the idea that Mars is the ideal candidate to host life.

A third of the planet’s ships depend on a single Norwegian company. And they have chosen Alicante for their global expansion

by

In the world of shipping, there is a silent giant whose technology is responsible for ensuring that a third of the world’s fleet is not lost at ocean or collided in port. This is Kongsberg, the Norwegian conglomerate controlled mostly by its State, which has turned the province of Alicante into an indispensable piece of its global chess board. Today, more than 30,000 ships they are capable of plowing the seas thanks to systems that are managed, maintained and repaired from offices located between La Vila Joiosa and the NOBO business center in the capital of Alicante. A strategic divorce to conquer the stock market. The news that has shaken the foundations of the industry this year is the segregation of the matrix. According to the company itselfKongsberg Gruppen ASA has decided to split into two independent entities to gain agility: on the one hand, the Defense and “Discovery” division (fishing and research); and on the other, Kongsberg Maritime, the jewel in the crown dedicated to navigation systems, which will begin trading separately on the Oslo Stock Exchange on April 23, 2026. This financial independence is backed by solid figures on Spanish soil. According to the newspaper The Informationthe Spanish subsidiary invoiced a total of 31.7 million euros in 2024, with a profit of more than five million. It is not surprising that Lisa Edvardsen Haugan, future CEO of the new independent company, claim that they are “unitarily positioned for value creation in the global maritime sector.” Why Alicante and not Vigo or Algeciras? The story of how a Nordic power ended up installing its nerve center in the province of Alicante has a component that is as human as it is strategic. In 1995, the company was looking for a headquarters in Spain. Although ports like Vigo or Barcelona seemed logical options, the executive in charge of the expansion opted for the coast of Alicante. The reason was the existence of a historical and consolidated colony of Norwegians in municipalities such as La Vila Joiosa or Altea. However, what began as a small delegation for the fishing sector—under the name Simrad Spain— has mutated into something much more ambitious. After the purchase of the maritime division of Rolls-Royce, the structure became too small. Today, the move of Kongsberg Maritime to the NOBO business center in the capital of Alicante responds to a need to attract talent. Miguel Ángel González, general director in Spain, points out that this change seeks to increase the attractiveness of the firm to retain engineers and software developers, in addition to reducing emissions due to staff travel by 30%. The brain of the autonomous boat. Alicante is not a simple administrative office; It is one of the only three resource hubs that the group has on the planet, along with Poland and Norway itself, capable of serving ships around the world thanks to its strategic position between the Atlantic and the Mediterranean. As explained by the company itselfnaval autonomy is not new — they have been developing Dynamic Positioning Systems (DPS) for 40 years that allow a ship to remain stationary at an exact point in the ocean without using anchors — but now the technology has reached a “critical mass.” Yara Birkeland: The world now look in amazement to the world’s first fully electric, autonomous and zero-emission container ship, developed by Kongsberg together with YARA. Reach Remote: This is a series of unmanned surface vessels (USV) that are controlled from a remote center. According to senior designer Erik Leendersthis allows a single captain to control several ships at once from dry land. The “Jewel in the Crown”: The DPS system is what allows that Sasemar (Maritime Rescue) oil platforms or rescue ships operate with extreme safety on the high seas. The horizon. The future of navigation involves electric motors that generate your own energy with the rotation of the propellers. To manage this complex flow of data, the firm Kognifai has launchedan Artificial Intelligence platform that optimizes ship operations. Although the technology is ready, the company’s technical report warns that the biggest current challenge is not engineering, but legislation. As the firm warnswe are in “uncharted territory” and the IMO still needs to define the rules for these ships without humans. What was born in 1995 as a fishing office in La Vila has become in 2026 the command post from which Norway and Alicante dictate the rules of the future of global trade by sea.

There is brutal competition to guard the fortunes of the planet’s millionaires. The same guy as always is winning: Switzerland

by

The ultra-rich around the world move their millions of dollars in search of the place safer for your fortunes. In recent years, countries in the Middle East and Southeast Asia they have stepped on the accelerator as a destination for the greatest fortunes in the world. However, amid the latest geopolitical tensions, a report from the consulting firm Boston Consulting Group reveals a disturbing fact: Asian millionaires are turning their gaze to the old and reliable Switzerland to protect your wealth. According what was published for him Financial Timesmany Asian millionaires are diversifying the refuge for their assets and, instead of keeping them in their place of residence in Hong Kong, Dubai and Singapore, they prefer to deposit part of their fortune in Swiss banks. Switzerland remains the world’s safe deposit box. According to the report Global Wealth Report 2025 Prepared by Boston Consulting Group, Switzerland managed $2.74 trillion in assets in 2024, which maintains it as the main offshore wealth center in the world. Very close to Switzerland’s management figures are important economic enclaves in Asia such as Hong Kong (which managed 2.65 trillion dollars) and Singapore (with 1.92 trillion dollars in the same year). The study estimates that, by 2029, these three destinations will concentrate almost two thirds of the new cross-border wealth. Boom of the rich in Asia. The study recognizes the enormous growth of Asian and Middle Eastern wealth centers, which have recorded a growth 50% since 2014. However, many of these funds end up in Switzerland, registering a increase in wealth cross-border savings held in the coffers of Swiss banks of 8.7% in 2024, up from 6.3% annually recorded in 2023. That is, although Asia has become a fertile ground for generating wealth, millionaires continue to see Switzerland as a safer place to store it. Geopolitical concerns. One of the main reasons for this behavior of the great fortunes settled in Asia are the political and geopolitical decisions that increase economic uncertainty. An example cited in the report points out that events such as the implementation of the national security law in Hong Kong in 2019 or the Russian invasion of Ukraine in 2022, raised questions about the security of assets in Asia. “Private banking focuses on diversifying geopolitical risk: clients are always looking for safe havens,” declared to Financial Times Giorgio Pradelli, CEO of the Swiss private bank EFG. “Clients increasingly began to feel that, geopolitically, the situation was less predictable and therefore it was important to have assets in different jurisdictions,” says Christian Cappelli, head of Julius Baer’s Asia office in Zurich. Financial Times. That is, they were betting on sending part of their fortune to Switzerland to protect themselves against economic blockades, political changes or war conflicts. London is no longer a refuge. On the other hand, the tax changes that the United Kingdom has implemented have caused London to lose much of your interest for millionaires Asians, putting Zurich back on the map. According to Christian Frie, head of the Asia-Pacific business in Switzerland for LGT Private Banking, the majority of Asian clients managed by his banking entity allocate between 10% and 15% of their assets outside their countries, mainly to Switzerlandaccording to the report The Global Entrepreneurial Wealth Report 2025 prepared by UBS.

Mars has just entered the exclusive club of planets with rays. This is discouraging news for NASA.

by

NASA’s Perseverance rover has captured a lightning strike on Mars for the first time. Although it may seem strange, it is only the fourth planet in which we have confirmed the presence of this type of electrical activity, after Earth, Jupiter and Saturn. Confirmed. Despite its thin atmosphere, scientists have suspected for decades that the red planet, with its constant whirlwinds and dust storms, must have some type of electrical activity. Now, thanks to the Perseverance rover, we finally have definitive proof. The discovery, published in the journal Natureconfirms that the Martian atmosphere crackles with electricity, although not exactly like the Earthly storms we know. They haven’t seen it, they’ve heard it. As much as we would have liked the Perseverance rover to photograph a blinding flash across the Martian sky, the first evidence of electrical activity on Mars is not visual, but auditory. NASA’s rover’s SuperCam instrument, equipped with a microphone originally designed to listen to the rover’s laser hitting rocks, has captured something unexpected: the sound of electrical discharges. Among dust devils. According to the data analyzed by the Jet Propulsion Laboratorythe rover recorded 55 electrical discharge events over two Martian years. Most associated with dust storms, and 16 of them when the rover was directly crossed by sand devils. “We got some good recordings where you can clearly hear the click,” Ralph Lorenz, Perseverance mission scientist, explains in a statement. But in a specific recording from sol 215 (the 215th Martian day of the mission), you hear not only the electrical crack, but also the swirling wind hitting the rover and grains of sand impacting the microphone. The triboelectric effect. How do these rays form on a planet without rain clouds? Because of the triboelectric effect, exactly the same physical principle that happens when we walk with socks on a carpet and then you touch a doorknob and, ouch, a spark jumps. On Mars, dust devils act like giant generators of static electricity: Hot air rises and begins to rotate, forming a vortex. When rotating, it raises dust and sand. The dust grains rub against each other, transferring electrons and generating charge. It’s not very encouraging. Although on Earth it also occurs in deserts, on Mars this effect is much more likely to result in electrical shocks. The Martian atmosphere is extremely thin, so the amount of charge needed to break air resistance and generate a spark is much smaller. This discovery is not just a meteorological curiosity; has profound implications for the planet’s chemistry and the search for life. Confirmation of these electrical discharges suggests that the Martian atmosphere may become charged enough to activate powerful chemical reactions. These sparks could be creating highly oxidizing compounds, such as perchlorates, which are very aggressive and can destroy the organic molecules (the building blocks of life) that the rover is trying to find.

We have just discovered three Earth-like planets orbiting two very close suns

by

The iconic scene of Luke Skywalker watching the double sunset on the planet where he was raised, Tatooine, is one of the most indelible images in science fiction. Now, thanks to NASA TESS Space Telescopewe believe there are three planets similar to Tatooine within 72 light years of Earth. A unique system. It’s called TOI-2267 and it challenges what we thought we knew about how planets form. According to research published in Astronomy & Astrophysicsthis binary star system hosts three planets similar in size to Earth. But what makes it extraordinary is not that it can have two-sun sunsets, but rather its compact architecture. Two very close suns. TOI-2267 is formed by two M dwarf stars (M5V and M6V) that orbit very close to each other, at a distance of only 8 astronomical units. To put it in context, in our solar system, Saturn orbits 9.5 astronomical units from the Sun. Until now, theoretical models suggested that such a close binary environment was too chaotic and gravitationally unstable to allow planets to form and maintain stable orbits. TOI-2267 proves us wrong. How it works. The analysis of the system, in which the Institute of Astrophysics of Andalusia had an important participation, reveals that the three planets cannot be orbiting the same star, since the system would be unstable. The most plausible configuration, and the one that excites scientistsis that two of the planets orbit the main star (TOI-2267A), while the third candidate orbits the companion star (TOI-2267B). This makes TOI-2267 the first known binary system to host planets transiting both of its stars. The next step. After discovering the system with the TESS space telescope and carrying out follow-up observations with the SPECULOOS observatory, from Chile and Tenerife, and the TRAPPIST telescope, the next step will be to use more powerful instruments, such as the James Webb Space Telescope to try to measure the masses, densities and even analyze the possible atmospheres of these worlds. This system not only proves that Tatooine exists, but that the universe is capable of forming planets in the most extreme and unexpected places we can imagine.

Astronomers have been theorizing about “planets kamikaze.” They just found one and is 100 times more violent than it was believed

by

We already know A good handful of exoplanetsbut astronomers of the European Space Agency have just added a fascinating category to the catalog of strange worlds. The Kamikaze planets. Using the Cheops space telescope, The first exoplature observatory of EuropeESA researchers have first observed a planet that causes flares in their own star, a suicidal custom that will end up sealing their own destiny. The “Kamikaze planets” are actually a phenomenon of cosmic self -destruction that has been theorizing since the 1990s. But it had never been observed directly, so far. And what astronomers have seen is a hundred times more energy than anyone had imagined. A violent neighborhood. The protagonist of this story is Hip 67522, a solar system located about 490 light years from Earth. Its star is a bit larger and cold than our sun, but it is very different: while the sun exceeds median age with 4.5 billion years, Hip 67522 is a teenage star of just 17 million years. Like any teenager, this star is full of energy, with a very agitated nucleus that does not stop turning, which makes it a very potent magnet. Around this violent cosmic magnet two planets turn. The one that interests us is the closest, Hip 67522 B, a world that completes an orbit in just seven days. The planet that plays with fire. Since they began to discover exoplanets, astronomers wonder if there are worlds orbiting enough close to their star to disturb their magnetic field and, in essence, “prick it” so that great flares are unleashed. Cheops space telescope observations They demonstrated that the planet Hip 67522 B is so close to its star that its own magnetic influence interacts with that of its host. The planet acts as a whip: as the star orbits, energy is accumulated in the form of waves along the lines of the star magnetic field. When these energy waves collide with the surface of the star, they trigger a gigantic solar flare, much more violent than expected. And absolutely destructive for the planet. Up to 15 lashes captured in camera. The Cheops telescope detected a total of 15 flares, almost all produced while the planet was ahead of the star from our perspective. This synchronization is the definitive proof: the fact that the flares occur just when the planet passes between us and the star confirms that it is the planet who is causing them. The tragic part of this story is that the planet is causing these gigantic energy explosions in its own direction. Hip 67522 B is being bombarded with six times more radiation than I would receive if it would simply stay still. The planet is shrinking. According to astronomers, in the next 100 million years it could go from being a gaseous giant of Jupiter’s size to a planet of Neptune size. It is a slow -chanted cosmic suicide.

No one has advanced NASA in the exploration of other planets from the USSR. China plans to do it even in Neptune

by

While NASA applies Efficiency Department cuts Directed by Elon Musk, China has presented the most ambitious space exploration program in its history. A SCIENTIFIC MISSIONS directed by him newly created Deep space exploration laboratory that would not only advance to the US in several milestones: no one would arrive in the Solar System. Kamo’oalewa (2025). With the launch of the Tianwen-2 probe, scheduled for May of this year, China aspires to become the third country to collect samples of an asteroid near the Earth. Japan had only done (twice) and the United States (after the recent Osiris-Rex mission). 469219 KAMO’OALEWA is a “miniluna”a terrestrial quasisisatelite between 40 and 90 meters in diameter that China aspires to “touch” with Tianwen-2, a mission that will also study the Elst-Pizarro comet-asteroid and that will serve as a learning for the future mission of recovery of Mars samples. Mars (2028). Tianwen-3 is the mission for bruise that could mark the Sorpasso Symbolic of the Chinese Space Agency to NASA, since the American mission of return of Martian samples (in which the European Space Agency also participates) is found right now in pause. Tianwen-3 is simpler than Mars Sample Return. If what NASA wants is to go find the rocks that have Carefully selected the Rover PerseveranceChina forms to reach the red planet, pierce the ground, collect at least 500 grams of samples and take off with a small rocket so that a return probe brings them to the earth. 2015 XF261 (2028). The same year that China plans to launch Tianwen-3, it would also launch its First major planetary defense mission. Two Chinese probes will follow the steps of the missions NASA Dart and Hera of that. One will impact the near Asteroid 2015 XF261 and the other will observe the impact to confirm that humanity has diverted a second asteroid. Callisto and Uranus (2029). The Tianwen-4 mission, whose launch is scheduled for 2029, has a double objective. It would arrive in Jupiter in 2035. A first orbiting probe Callisto, one of the moons of the gaseous giant, at the same time as JUICE DE LA ESA Orbit Ganímedes, another of its moons. A second probe, equipped with thermoelectric radioisotope generators, would take advantage of Jupiter’s gravitational assistance to get to Uranus in 2045. It would be one of the first scientific missions to Uranus, which He received the visit of the Voyager 2 probe In 1986. Venus (2033). Another sampling recovery mission, but this time atmospheric. A Chinese probe would travel to neighbor Venus and take its “air” to analyze whether it has microorganisms or possible biological traces, such as Some recent studies suggest. Neptune (2033). A freshly proposed mission to the last planet of the solar system would orbit the ice cream giant and display an atmospheric probe equipped with a balloon, in addition to performing flycards from its Triton moon. With a useful life of up to 20 years to the thermoelectric generators of radioisotopes, it would be the first probe sent exclusively to Neptune. For its launch, the future CZ-9 rocket, the “Chinese starship” would be used. Mars (2038). In addition to a manned station on the moon, China plans to display an autonomous robotic station on Mars to investigate techniques for the use of Martian resources that could serve for future manned missions. China plans to step on Mars in the 2040s. Triton (2039). The second Chinese mission to Neptune and his Triton moon is the most ambitious of the program because he would use a nuclear fission reactor to feed the ship’s electrical thrusters. All that energy would not only allow you to orbit Neptune, but also penetrate the ice from the Triton surface to explore the hypothetical ocean that is hidden below in search of life.

They are planets orbiting other stars to 130 light years

by

One of the original purposes of the James Webb space telescope was the direct observation of exoplanets: distant worlds that orbit stellar systems other than the sun. The latest images of the 10,000 million dollars observatory demonstrate the level of detail that is capable of capturing. Young and gaseous. The Webb Telescope, operated by NASA, the European Space Agency (ESA) and the Canadian Space Agency (CSA), has been observing a planetary system to 130 light years from the Earth. At the tender age of 30 million years, this neighborhood called HR 8799 It is much younger than our solar system, which is 4.6 billion years old. The four planets in the photo that revolve around the star HR 8799 are gaseous giants similar to Jupiter and Saturn. Being so young, in addition to giants, they retain the residual heat of their formation, which makes them emit a large amount of infrared light. This light is what has allowed Webb Space Telescope Capture clear and direct images of exoplanets. An important finding. One of the most surprising aspects of these observations is the remarkable presence of carbon dioxide in the atmospheres of the four giant planets. A study published by The Astronomical Journal Associates CO2 to a large number of heavy elements such as carbon, oxygen and iron in the gaseous body of these exoplanets. The study supports the theory of core’s accretion training, which is the same mechanism proposed by astronomers for the formation of Jupiter and Saturn in our solar system. According to this theory, the giant planets begin forming solid nuclei that then attract large amounts of gas from the protoplanetary disk that surrounds a young star. Cooked over low heat. The Chemical composition observed by the Webb In the HR 8799 system it is a clue that the planets were formed by slow accumulation of heavy materials, instead of faster alternative processes. Scientists have also been able to analyze important differences between the planets. For example, HR 8799 B, the farthest from its star, shows greater carbon dioxide wealth, while HR 8799 E, the closest to its star, seems to have formed in very different conditions, in a warmer region and with a different composition. Another Nircam job. Thanks to the Nircam Chamber and its coronograph, which blocks the bright light of the central star, the Webb has not only been able to observe the HR 8799 system, but also 51 eri ba relatively cold and young planet located in the 51 Eridani system, 96 light years from the earth. This orbit planet at a considerable distance from its star, similar to a location between Saturn and Neptune of our solar system. In this case, the webb has also detected a rich atmosphere in carbon dioxide, which further supports the hypothesis of the solid nucleus as a training mechanism.

What planets can be seen with the naked eye from Spain in the great alignment (and what do we need for the rest)

by

A planetary alignment is approaching very rare: one that will allow us to see all the planets (with permission from the Explaneta Pluto) of the solar system in the night sky. If the conditions allow it (something that It doesn’t seem very likely), On Friday we can see this great planetary alignment. Seen and not seen. Part of the protagonists of This planetary alignment They may be seen at first glance on Friday night. To see the rest we will have to resort to optical instruments, such as prismatic or telescopes, or even with a teleobjective camera or Zoom of a certain length. With the naked eye. A good part of the planets of our solar system can be seen with the naked eye, brilliant as stars, sometimes easier to see than these. In this list are the rest of the rocky planets inside our solar system (Mercury, Venus and Mars), and the two great gaseous giants (Jupiter and Saturn). The real visibility of each of these planets will depend on several factors, such as light pollution or meteorology. Of all these planets, the most difficult to capture will be Saturn. The reason is that when the dusk arrives, the planet of the rings will be very low by the horizon, and will disappear after this Around 20:00 (The exact time will depend on our location). Something similar will happen with Mercury, which will also disappear by the horizon just an hour after the sun. At the opposite end is Jupiter, which will be perhaps the planet with greater visibility during today. The visibility of Mars and Venus will be relatively good. Not so powerful. And what about the rest? If we exclude dwarf and satellite planets, our solar system has two other planets: Uranus and Neptune. These are the two major planets that are not visible to the naked eye in our space neighborhood, so they could only be discovered after the invention of telescopes. If we want to see Uranus, resorting to one of these gadgets is a good idea. The magnitude of this planet, discovered in the 18th century, is approximately 5.6 According to the portal calculations In-the-sky.orgwhich places this planet in the limit of what is visible by the human eye. That is why, if we want to see this planet, it is necessary in the necessary practice to resort to a telescope or, at least, to prismatic ones. Neptune however is a bit more elusive. Already discovered in the nineteenth century, Neptune’s magnitude is around 7.7 According to Del Portal In-the-sky.org. This puts it out of the range of what we can see with our own eyes. In any case, an especially powerful telescope is not necessary to see this planet. Other issues to take into account. To improve our visibility tonight there are three factors to take into account. The first, light pollution. Some of the planets that will be visible will be only in a very tenuous way, so away from areas where light pollution is minimal will be decisive if we want to see all visible planets today. The second of these factors is The weather. The night is not presented today as the most appropriate for the observation of heaven. A storm Located in the south of the Peninsula will leave skies covered in a good part of the country. Finally, it is convenient to know how to locate the planets we are looking for. For this we can assert us from different resources, including various applications Focused on astronomy and celestial observation.
