the strange inhabitants of the Antarctic abyss

In the frozen, forgotten depths of the South Atlantic, an international team of scientists has achieved the unexpected: confirming the existence of thirty completely new marine species for science. Among them, a creature stands out that challenges what we know about life in the deep ocean: a spherical sponge covered in hooks, capable of catching its prey with such forceful efficiency that the team itself baptized it as “death ball”. We don’t know everything. With this type of news, science places our feet in reality, since although we have been populating this planet for many years, there are still things that we do not know. An example are these new species that show us that in the depths of the ocean we have a great mystery for humans and that there is still a way to surprise us with our planet. A predator. Most marine sponges They are considered “peaceful”filter feeding and causing no further harm to anyone. But the Chondrocladia sp. novfound more than three kilometers below the surface near Montagu Island, uses microhooks that act as a kind of “deadly Velcro” on crabs and other invertebrates, which it slowly absorbs. Visually, this is a sponge that is actually quite surprising, since it is white and has appendages ending in small balls. In this way, it managed to gain the attention of specialists who have described it as one of the strangest animals of the entire expedition. This is something that breaks with what a traditional sponge does that we all have in mind, which simply feeds on particles and remains in the water itself. But this new species is committed to feeding on other living beings and on those that are above the food chainas the study researchers point out. Technology has been key. Right now, accessing the seabed is a real challenge for humans. One of the great impediments is the great pressure that exists in that environment that becomes really hostile. But thanks to technological advances it has been achieved. This specific investigation has had a underwater robot named SuBastian and high definition cameras. The result of the expedition was thousands of hours of video and nearly 2,000 specimens among the images that had to be analyzed. But the species were not the most notable part of this research, since new hydrothermal springs, coral gardens with volcanic structures were also discovered, and a juvenile colossal squid was recorded for the first time. ​ Not just sponges. It is a fact that on the seabed there are many species that are truly strange, including the so-called ‘death balls’, but they were not alone in this rarity. Other species that surprised the researchers were the following: Zombie worms (Osedax sp.), capable of feeding exclusively on the bone tissue of whales and large vertebrates. ​ Rare mollusks, bivalves and black corals adapted to hydrothermal and volcanic environments.​ A complicated process. Verifying that these findings are true is not something easy to achieve. In this case, the findings were made this August at the University of Magallanes in Chile where specialists from eight countries applied accelerated identification techniques: from in situ imaging to genetic comparison, in a process that seeks to reduce the years of waiting to catalog new species.​ Images | @TuCpakoa In Xataka | We are clogging the ocean’s carbon toilet and it is something that is only going to cause us problems

110 years later we finally know what sank the ‘endurance’ in the Antarctic. The culprit was not the ice: it was much worse

He Endurancethe legendary ship of Ernest Shackletonbecame a symbol of resistance and heroism after its sinking in the icy waters of the Weddell Sea in 1915. There began the myth, because during more than a centuryits end was wrapped in a halo of mystery, attributed to the lethal coup of the ice against its rudder. Now, science He has revealed That the truth was more complex and, in a way, disturbing: the ship was never prepared to survive. The myth and the truth. As we said, for more than a century, 110 years to be exact, Ernest Shackleton’s heroic story and his antarctic ice crew was accompanied by the conviction that the endurance was the wooden ship more robust of his timevictim of a fatal blow of the ice against his helm. However, Recent research They have dismantled that narrative. The thorough analysis of the wreck discovered in 2022 reveals that the ship I was convicted From the beginning: it was not a single impact that sank it, but the accumulation of compressive forces that crushed their weak structure and, very important in the final story, Shackleton I probably knew When he left for Weddell. The expedition trapped. Endurance sailed in 1914 with the ambitious plan of cross the Antarctica on footbut at the beginning of 1915 he was caught in a solid ice. For ten months the crew resisted on board until the pressures began to deform the ship. The covers were combined, the helmet vibrated with a crash and the newspapers of the sailors picked up the sound of the creak of the wood under huge forces. On October 27, 1915 Shackleton ordered to leave the shipand weeks later the helmet ended up sinking after a succession of pressure onslaught that started masts and opened the structure in two. Idealized cross sections of the first Antarctic ships. The endurance was of the type (a); The type Deutschland (B) Fortress with mud feet. Far from being the invulnerable ship of the legend, the endurance was born as a ship of Polar and Hunting Tourism of bears and morsas in the Arctic. Its design lacked the critical reinforcements to survive trapped in an icy sea: it had no diagonal beams that kept the bands of the helmet or racks that supported the machine room, its most fragile area. Over there, According to witnesses As the scientist Reginald James or Captain Frank Worsley, the iron plates combined and the soils bulging while the ice pressed incessantly. The Rudder and the keel departed, but they were not the cause but the consequence of that structural weakness. Pecio discovered in 2022 Shackleton knew it. It is one of the keys that light has seen now. The most revealing thing is that Shackleton I did not ignore Those defects. He had participated in rescues from other ships shattered by ice and advised the German Wilhelm Filchner reinforce with diagonal beams Your Deutschlandthat thus managed to survive eight months trapped. Even in a letter to his wife he admitted that the endurance was not as solid as The Nimrodthe ship of your previous expedition. Even so, He acquired it Without modifications, moved by the urgency of undertaking a colossal project in the midst of their debts, their personal failures and competition with other explorers for reaching Antarctic glory. The re -written history. He New study of Jukka Tuhkuri Disassemble the myth of the invulnerability of the endurance, showing that it was an inappropriate ship faced with a relentless environment. However, this finding does not decrease the figure of Shackleton, but it frames it With more realism: A leader who risked aware that the adventure could cost the ship, but that miraculously saved his entire crew. At a time when polar exploration was a jump of faith towards the unknown, the wreck of the endurance was not only the end of a ship, but the proof that even the stronger wood yields Before ice pressurewhile human will manages to survive where the technique fails. Shared destination. The truth is that the Endurance drama It was not an isolated episode. Decades earlier, in 1876, twelve American whales They sank in front of Alaska for lacking the necessary reinforcements against compressed ice, dragging with him the livelihood of hundreds of families. Something similar happened in 1903 with The Antarctica Swedish ship trapped and shattered in the Weddell Sea. And, in contrast, the case of Deutschland It demonstrates how simple modifications could make the difference between sinking and survival. If you want also, all these episodes draw a pattern: polar ice does not forgive improvisations or risk economies. Shackleton, with his leadership instinct, achieved what other captains They did not achieve: save all his men, although at the expense of expose them to sacrifice of a ship that had never had to face the brutality of the white continent.

There are only two places in Spain from which you can see the eclipse of the 21st: the Spanish Antarctic Bases

Eclipses have given much to talk about in recent months. In April of last year millions of Americans saw an eclipse whose total concealment path furrowed from south to north the country. Something closer, in March of this year we had a small snack of the row of eclipses that we can see in the coming years. But some eclipses go unnoticed. A new eclipse. On Sunday there will be a new partial eclipse of Sol. The eclipse will begin approximately At 17:30 UTC7:30 p.m. Spanish peninsular (CEST); and will last almost until 21:54 UTC, or 23:54 Cest. Like other solar eclipses, this occurs on dates close to a lunar, in this case The last day 7 September. The beginning of the eclipse will be given on Pacific waters, near the Samoa archipelago. While being a partial eclipse there will not be a moment of total concealment, it will be at 19:42 UTC (21:42 CEST) when I know the moment of maximum concealment. According to Explain the National Geographic Institute (IGN), the maximum magnitude of the eclipse will be 0.86, but the inhabited settlements can only see the sun disappear in Something more than 72% of its surface. As Ign explains, after 264 minutes of eclipse, the sun will shine fully, being the waters of the ocean, near the Antarctic Peninsula the last to see the solar concealment. The eclipse of the antipodes. Sunday’s eclipse will be almost a tracing that was seen on March 29, only will run through the antipodesthe opposite side of the globe. The partial eclipse will be visible in the islands of New Zealand and other archipelagos of the southern Pacific. Almost “refile” can also be seen on the west coast of Australia, including Sydney and on the island of Tasmania. A very small fraction of humanity will be the one that this eclipse can see. In addition to those that inhabit the mentioned areas, in Antarctica the eclipse may be seen by those residing in some bases, including the Spanish located in the Southern Shetland Islands. The areas where the eclipse will be seen are best in the south of New Zealand and in some areas of the Antarctica continent, specifically in the region known as Earth of Oates, as well as in some small archipelagos located in the region. Waiting for a turn. Meanwhile we are waiting for the three eclipses, two plots and one annular, visible in Spain and part of Europe Between 2026 and 2028. The first of these eclipses will be the August 12 of 2026 and will be a total eclipse. The second will happen on August 2, 2027 and will also be total. The last will be annulled and will arrive on January 26, 2028. Meanwhile the world will see other eclipses. The following, for example, will arrive February 17 of 2026. It will be annulled but it can also be seen only from the southern hemisphere, with its annular phase only visible from Antarctica. February 7, 2027 an eclipse, also cancel, It will travel part of South America and can be seen partially from much of Africa and southern Spain.
