PolitiFacts ruling: False Heres why: A group of scientists claims they have found proof of life — in the form of fungi — on Mars, according to a blog post and posts on social media. "Scientists Claim to Spot Fungus Growing on Mars in NASA Rover Photos," read a Futurism article headline. "MARS’ MAGIC MUSHROOMS Life on Mars shock claim as ‘growing FUNGI’ spotted in Mars Curiosity Rover snaps," read another in The Sun. The articles point to a study published by a group of scientist...

Ancient Mars only received a third of the sunlight that shines down on Earth,

Icy clouds on ancient Mars may have given rise to lakes and rivers Scientists have long puzzled over how Mars, a cold and dry planet, was once warm enough to support liquid water. Digital illustration of water on Mars In a recent study, researchers created a computer model to explore how varying levels of surface ice would have affected clouds above the Martian surface. The results showed that icy, high-altitude clouds would have formed if Mars was covered in relatively small amounts of...

At some point in its early history, Mars could have had a thin layer of icy, high-altitude clouds that caused a greenhouse effect, new research suggests. The theory helps explain one of the great puzzles of modern space science that the view from NASA’s Perseverance, which just landed on Mars, neatly sums up: Today Mars is a desert planet, and yet the rover is sitting right next to an ancient river delta. “Mars is important because it’s the only planet we know of that had the ability to s...

The view from NASA's Perseverance rover, which recently landed on Mars, neatly summarizes one of the great mysteries of modern space science: Today, Mars is a desert world, but the rover is seated right next to an ancient river delta.

One of the great mysteries of modern space science is neatly summed up by the view from NASAs Perseverance, which just landed on Mars: Today its a desert planet, and yet the rover is sitting right next to an ancient river delta. The apparent contradiction has puzzled scientists for decades, especially because at the same time that Mars had flowing rivers, it was getting less than a third as much sunshine as we enjoy today on Earth. But a new study led by U...

(Credit: NASA and JPL-Caltech) (CN) — The latest of NASA’s rovers to successfully land on Mars has found an advantageous location right next to an ancient river delta, and based on new computer simulations, experts believe the now-barren planet could have had a thin layer of icy clouds at one point, allowing water to flow on the surface. The study was published Monday in the journal Proceedings of the Nationa...

Early in its history Mars may have had a thin layer of icy clouds creating a greenhouse effect that kept conditions warm enough for water to flow, study finds. As seen in images shared by NASAs Perseverance rover, Mars is a dust covered desert planet with no clear signs of life, but the SUV-sized vehicle is currently exploring an area that was once a river delta, formed by flowing water.    At a time when Mars had rivers and lakes the sun was weaker than it is today, with the Red Planet rece...

    “Liquid magma is actually quite runny,” said University of Chicago planetary scientist, Edwin Kite, about a new study by University of Chicago and Stanford University researchers suggesting a mechanism where planets could develop atmospheres full of water vapor similar to what makes life on Earth’s surface possible, regulating our climate and sheltering us from damaging cosmic rays. Magma Oceans Suck Hydrogen  Out of the Atmosphere “So it also turns over vigorously, just like oce...

Researchers created a model to predict how hot worlds keep their atmosphere  They say that many start with a large cloak of hydrogen but lose it early on This leaves a rocky world underneath that has a cracked and molten surface As the hydrogen is stripped by the star t reacts with the heat to form water which then falls to the ground as water vapour, eventually forming into an atmosphere
