Images from NASA's Perseverance rover have confirmed that Jezero Crater was once an ancient Martian lake. Moreover, there is also a large delta formed by a river and evidence of flash floods that carried large boulders into the lake.
Photosynthesis in Venus' atmosphere may be possible, according to a new study. The findings support the idea that microbes could exist and even thrive in the more temperate regions of the planet's cloud layers.
Mars was once a wet and habitable world, so what happened to change that? According to a new study from Washington University in St. Louis, Mars' small size is likely to blame for why it lost most of its water and atmosphere.
NASA scientists say that there were once thousands of volcanic eruptions on Mars. These explosive blasts, in the northern Arabia Terra region, were "super eruptions," the largest and most powerful kind known. The intense activity continued for about 500 million years, about four billion years ago.
Paul Scott Anderson has had a passion for space exploration that began when he was a child when he watched Carl Sagan’s Cosmos. While in school he was known for his passion for space exploration and astronomy. He started his blog The Meridiani Journal in 2005, which was a chronicle of planetary exploration. In 2015, the blog was renamed as Planetaria. While interested in all aspects of space exploration, his primary passion is planetary science. In 2011, he started writing about space on a freelance basis, and now currently writes for AmericaSpace and Futurism (part of Vocal). He has also written for Universe Today and SpaceFlight Insider, and has also been published in The Mars Quarterly and has done supplementary writing for the well-known iOS app Exoplanet for iPhone and iPad.
