Study suggests there are volcanic explosions on Venus | Digital Trends Spanish

Some time ago, the existence of life on Venus had been ruled out because of the presence of phosphine, which could have suggested that. And now, a new study sheds other clues on the same topic: Phosphine on Venus could be due to volcanic activity. Originally, it was believed that there could be life on Venus because phosphine, on Earth, exists thanks to microscopic organisms or because it is produced in some industries. However, a group of scientists who continued to study the Venus data now suggest that phosphine is due to volcanic explosions and that we may well be dealing with erupting volcanoes. These volcanoes, in turn, would throw phosphite into the planet's atmosphere and this, when combined with other elements such as sulfuric acid, could be transformed into the previously obs...

Mars and Venus will appear just a finger’s width apart in the night sky on Monday and Tuesday. Here’s how to see it.

Mars and Venus are about to line up in the night sky, getting so close on Monday and Tuesday that they'll almost seem to touch.An astronomical event in which celestial bodies align in the sky like this is called a conjunction.All month, Mars and Venus have been creeping nearer to one another. After sunset on Monday night, the two planets will appear so close together that a full moon couldn't fit in between. That's just a finger's width apart if you hold your hand up to the sky, according to NASA. The two planets will actually get closest together in the early hours of Tuesday morning, but daylight will make that impossible to see. So instead, people will have to wait until after the sun sets on Tuesday to see the two planets...

According to study, life could exist in the clouds of Jupiter | Digital Trends Spanish

An international team of scientists published a study in Nature Astrology on the activity of the water in the clouds of Venus. As a main conclusion, the research indicates that the effective concentration of water molecules in the clouds of Venus is too small to support life like that known on Earth. "We have not found that the water level is slightly below what the most extreme organisms need, but that it is 100 times lower than it would be necessary," explained John E. Hallsworth, leader of the study. The surprise is on the account of Jupiter, who showed that its clouds have a high enough water concentration and a suitable temperature for, in theory, Extremophilic organisms to survive. "I am not suggesting that there is microbial life on Jupiter because it would have to have other req...

Moving plates discovered on the surface of Venus | Digital Trends Spanish

Scientists have discovered that the surface of Venus would not be completely static, but quite the opposite: it is made up of fragments that move and collide with each other, thanks to the fact that they are on a moving and semi-liquid material that could be similar to lava. This phenomenon on the surface of Venus suggests that the inner mantle of the planet is in motion, according to the recently published study. The authors explain that Venus has long been known to have various tectonic plates similar to Earth's, but smaller and resembling "ice sheets floating in the ocean." Scientists believe that the mantle of Venus is in motion thanks to the heat that emanates from the nucleus and generates a kind of current, which has as a consequence what happens to the upper parts of the crust....

Now a study says there are no signs of life on Venus | Digital Trends Spanish

On September 14, 2020, scientists from the University of Cardiff published a study in which they revealed that they had found traits of life on Venus. The news, which appeared in the magazine Nature Astronomy, logically caused repercussions worldwide. The team, led by astronomer Jane Greaves, claimed to have detected phosphine on Venus, a gas that - on Earth - can only be produced by living microscopic organisms. To be clear, the researchers never explicitly stated the existence of life on Venus; they simply pointed out that it could be an explanation for the presence of phosphine. But just a month later, another team of scientists refuted the findings of Greaves' study, it reported. Gizmodo. Pot They took the same data as the Cardiff University researcher, which was collected by ...

They propose to build on Mars with insect dust | Digital Trends Spanish

Chitin is the second most abundant organic polymer on Earth, after cellulose. This is produced and metabolized in almost all biological kingdoms and is a major component in the cell walls of fungi, the exoskeletons of arthropods - such as crustaceans and insects - and the scales of fish and amphibians. It is present, for example, in the shell of lobsters and its use has shown important benefits for the cicatrization of the wounds. But what scientists from the Singapore University of Technology and Design unveiled on September 17 went further. The researchers propose using chitin as a material to build tools and human shelters on future missions to Mars, it reported. Notipress. The main author of the report is the Spanish Javier G. Fernández, who has already developed o...

After hint of life, Nasa evaluates two missions to Venus | Digital Trends Spanish

On Monday, September 14, astronomers from the European Southern Observatory (ESO) announced the discovery of a rare molecule, phosphine, in the clouds of Venus. Detection would be a clear indication of life on the neighboring planet. And this Thursday, NASA announced that in April 2021 it could approve two scientific missions to Venus that, according to the scientists involved in the project, could help determine if that planet harbors life, the agency reported Reuters. In February, the US space agency shortlisted four missions that are now being reviewed by a panel of NASA experts, two of which would involve robotic probes to Venus. One of them, called DAVINCI +, intends to send a probe to Venus. Instead of focusing on the planet itself, it will focus on the gases th...

Carl Sagan predicted the possibility of life on Venus in 1967 | Digital Trends Spanish

This Monday, September 14, an international group of scientists announced the discovery of phosphine (PH3) in the clouds of Venus. Scientists have pointed out that it is an astonishing and unexpected finding, which leads them to deepen their research on the possibilities of life in the atmosphere of the neighboring planet. The discovery has caused a stir in the international scientific community. However, more than fifty years ago, the famous astronomer and science popularizer Carl Sagan had already suggested the possibility of life in the atmosphere of Venus. Through your study Life in the clouds of Venus?, published the magazine Nature In 1967, together with Harold Morowitz, Sagan drew attention to the possibilities offered by the clouds of that planet for the disco...

Astronomers find signs of life on Venus | Digital Trends Spanish

An interesting discovery that could have great implications for world astronomy is the one presented at the Nature magazine this Monday, September 14, as a group of researchers found traits of life on Venus. The finding is the detection of gas in the atmosphere of the blue planet: With powerful telescopes, they have detected a chemical, phosphine, in the thick Venusian atmosphere. After much analysis, scientists claim that something now alive is the only explanation for the source of the chemical. "This is an amazing and 'unexpected' find," he said. Sara seager, a planetary scientist at the Massachusetts Institute of Technology and author of the articles (one published in Nature Astronomy and another sent to the journal Astrobiology). "It will definitely spur more research on the...

They warn that Venus has been covered by a giant cloud for decades | Digital Trends Spanish

A gigantic "wave" of clouds has been covering the planet Venus for 35 years without any astronomer noticing. This is indicated by an article published in the journal Geophysical Research Letters and which reports Reverse. The discovery was made thanks to the work of the Akatsuki mission, of the Japanese Space Agency (JAXA) Akatsuki has been orbiting Venus for 10 years. In 2016, it sighted, for the first time, what appeared to be an atmospheric wave that extended over the planet, known for its high temperatures. To observe the phenomenon, JAXA used NASA's infrared telescope in Hawaii, and focused on the middle and lower layers of Venus' atmosphere. They found that the giant cloud had stretched 4,700 miles (7,563 kilometers) across the equator of Venus at altitudes between 48 and 5...
