Avi Loeb is back at it. While NASA deploys an unprecedented fleet of cameras and telescopes to observe the third interstellar visitor in history, the Harvard physicist points out an orbital coincidence with Jupiter so precise that, in the absence of explanation, it defies chance. A little context. The solar system has a new guest … Read more
The technological transformation in aerial combat has reached a point where legacy tactics of the 20th century have ceased to offer minimum guarantees of survival. For decades, pilots could rely on low-flying flight to penetrate hostile defenses: the curvature of the planet, terrain shadows, and background noise hid planes speeding below the radar horizon. That … Read more
In the fight against cancer there are many ‘weapons’ that we have at our disposalsuch as chemotherapy or radiotherapy. The problem is that these are assimilated like bombing a city to destroy a single house: it is achieved, but with a lot of collateral damage. But this can be solved if We attack only what … Read more
Under the earth we walk on beats an energy that is born from internal heat, silent, so constant that neither the night nor the clouds can interrupt it. We don’t see it, we don’t hear it, but it is there: an engine running since the planet was formed. In recent decades, as we looked to … Read more
The crew of the Shenzhou-20 spacecraft, which was scheduled to land this Wednesday in Inner Mongolia, has been forced to postpone its return to Earth. The cause is not bad weather, as is usual in manned flights, but the most feared enemy of modern space exploration: a probable impact of space debris. Evaluating risks. China … Read more
Science is largely in agreement when it suggests that the Earth’s temperature it increases more and moreand logic could lead us to think that the world is going to become in a real desert like the one in Almería. But to everyone’s surprise, what can happen is a great ice agethat is, everything ends up … Read more
A team of scientists, analyzing the tiny and invaluable samples of the asteroid Ryugu brought to Earth by the Hayabusa2 missionhas made a discovery that shakes our understanding of water in the early solar system. The discovery, published in the prestigious magazine Naturereveals that liquid water flowed in Ryugu’s progenitor body more than a billion … Read more
When we think about mass extinctions, we almost always The asteroid that wiped out the dinosaurs comes to mind. But the universe has much more spectacular ways of reconfiguring life, as pointed out a scientific study which suggests that at least two of the ‘Big Five‘Earth extinctions were not caused by space rocks, but by … Read more
Before we looked at the sky to predict the weather. Now we look at the forecast in an app provided by incredibly powerful simulations based on radar and satellite data. Thus, we can see the path of a hurricane days before it makes landfall, potentially saving thousands of lives. But what about the “tornadoes” that … Read more
China has just moved a piece that can alter the global board of strategic minerals. Beijing has approvedtwo official announcements that establish a new regime of control over the rare earth and technologies linked to its extraction, processing and manufacturing of magnets. The change is not minor: any product manufactured outside the country that contains … Read more
