They confirm that Mars has a liquid and metallic nucleus | Digital Trends Spanish

The seismic signals recorded on Mars by NASA's InSight mission confirmed that the planet has a liquid and metallic core. An international study has also shown the size of the nucleus, the structure of the crust and the mantle of the red planet. Thus, the study of the signals of a dozen marsquakes recorded by an ultrasensitive seismometer deployed by NASA made it possible to determine the internal structure of Mars. According to the study, the planet's liquid core would have a radius of about 1,830 kilometers. According to the researchers, this size suggests the presence of light elements, such as sulfur, oxygen and hydrogen. While the interior of the core could be made up mainly of iron and nickel. “This work provides the first direct measurements of the inner layers of another planet...

The light of the stars, key in the origin of the Earth | Digital Trends Spanish

In 2011, scientists discovered that solar wind samples brought to Earth by the Genesis mission showed that oxygen isotopes in the Sun differ from those found on our planet, the Moon, and the other planets and satellites in the solar system. According to experts, at the beginning of the history of the solar system, the material that would later become planets received a strong dose of ultraviolet light, this could explain the difference. At that time, when wondering where it came from, two theories emerged. One of them pointed out that the ultraviolet light came from our then young sun, or from a nearby large star in the so-called solar stellar nursery. Now researchers at Washington University in St. Louis have determined that the second hypothesis was most likely. "We knew we were born...

Wall-E: a message for humanity that turns thirteen | Digital Trends Spanish

Wall-E became one of Pixar's most successful films and one of the most remembered animated films of recent times. The story of the charming trash compactor robot made a profound impact on viewers, especially through the messages it delivers. The film was released on June 27, 2008 and won the award for best animated film at the 2009 Oscars. The Andrew Stanton-written film has been described as a cry of alarm towards humanity and an invitation to care about the health of our planet. The premise of the film is enough to cause us concern. Wall-E is in charge of collecting and compacting the garbage that is on Earth, after humans were forced to abandon it because it was impossible to inhabit it. The best thing about the Pixar film is that it delivers an optimistic message, despite everythi...

Meteorite provides important information about water on Mars | Digital Trends Spanish

An investigation carried out by the University of Tokyo revealed evidence of water from 4.4 billion years ago in a Martian meteorite discovered in the Sahara desert in 2011. Although it was already known that Mars harbored water about 3.7 billion years ago, with this new analysis of the NWA 7533 meteorite, the researchers estimate that the water was likely present a long time before. For researchers, this type of analysis helps to understand how Mars was formed and what the process of evolution of its crust and mantle was like. Also, the findings are in line with the hypotheses that hold that water could be one of the substances that occur naturally during the formation of planets. This look would distance itself from the theory that states that the meteorite, nicknamed "Black Beau...

The Earth shakes every 26 seconds and nobody knows why | Digital Trends Spanish

It has been documented for decades, but no one has yet been able to explain why it happens. The Earth shakes, shakes gently every 26 seconds, although none of us can perceive it. Yes, seismologists do it through a small "blink" in their detection devices, but this slight record only serves to add to the mystery. The pulse or "microsism" was first recorded in the 1960s by a researcher named Jack Oliver of the Lamont-Doherty Geological Observatory. Back then, Oliver discovered that the pulse came from somewhere in the southern or equatorial Atlantic Ocean and was strongest in the Northern Hemisphere summer months. Meanwhile, in 1980 Gary Holcomb of the United States Geological Survey realized that microseism gets stronger during storms. Almost three decades later, scientists at the ...

Watch George Clooney’s Netflix Post Apocalyptic Tape | Digital Trends Spanish

2020 is probably not the best time to tackle the post-apocalyptic issue (or maybe it is). What is true is that given the shortage of new releases, any new release is welcome and Netflix knows that. The streaming service just released the trailer for The Midnight Sky, starring and directed by George Clooney, charged with a post-apocalyptic atmosphere that makes us think that the Earth could be worse than it is now. The film shows Augustine (Clooney), a lonely scientist who works at a station in the Arctic. Their only important mission seems to be to prevent a group of astronauts from returning to Earth, but why? The occurrence of a global disaster has left the planet in very poor condition, making life on its surface difficult. The problem (one of many) is that Clooney cannot make ...

This asteroid “is worth” much more than the entire world economy | Digital Trends Spanish

Psyche is a strange asteroid that is 370 million kilometers from Earth. It is classified as one of the most massive in the main asteroid belt of the Solar System, which orbits between Mars and Jupiter. It is about 226 kilometers wide and unlike most asteroids, which are icy and rocky, Psyche appears to be metallic. Being so dense and metallic, it is thought that Psyche could be the leftover core of a planet that failed during its formation, which is known as a protoplanet. Thanks to observations made using the Hubble Space Telescope, astronomers have been able to get a clearer image of the asteroid. Hubble. "We have seen meteorites that are mostly metal, but Psyche could be unique in that it could be an asteroid that is entirely made of iron and nickel," explains researcher Tracy ...

Some exoplanets may be watching us | Digital Trends Spanish

It is possible that our planet is currently being observed from billions of kilometers away. Is it a disturbing idea? A group of astronomers has pointed out that some exoplanets, that is to say planets beyond our Solar System, have a direct line of sight to observe the biological properties of the Earth from very far away. Astronomers from the Carl Sagan Institute of Cornell and Lehigh University have identified 1,004 stars similar to our Sun that could contain Earth-like planets that would be able to detect the chemical traces of life on our planet. The article was already published in the Monthly Bulletin of the Royal Astronomical Society and is titled "What Stars Can See Earth as a Transiting Exoplanet?" "Let's reverse the point of view of other stars and ask from what point of...

This was the descent of OSIRIS-REx on the asteroid Bennu | Digital Trends Spanish

It was a maneuver as singular as it was risky, which fortunately we were able to follow live on the internet. This Tuesday, October 20, NASA's OSIRIS-REx spacecraft descended on the asteroid Bennu, which is currently more than 300 million kilometers from Earth. The mission was to collect samples of the asteroid, which may become a threat to Earth for the next century, according to astronomers. In fact, it is believed to have a one in 2,700 chance of hitting Earth during one of its approaches by the end of the next century. The collection was also intended to find more information about Bennu, which is considered a relic of the Solar System, and can yield data on the molecular precursors of life on our planet. For this reason, it was a transcendental mission which could be observed ...
