Researchers suggest that Mars' subsurface lakes beneath the south polar ice cap may not actually be lakes after all. The first presumed lakes were discovered in 2018 and 2020, and now radar images from Mars Express reveal even more. But many of them are in locations too cold for even salty water to stay liquid.
A new study from scientists at LMU in Germany says that there could be enough heat and liquid water on moons of rogue planets - free-floating worlds with no suns - to support life. Cosmic rays could drive processes such as photosynthesis, instead of direct sunlight.
A new study from researchers at the University of Naples in Italy suggests that highly-evolved, Earth-like biospheres may be rare on exoplanets. Many stars either don't emit enough energy for life to develop past the basic photosynthesis stage or don't live long enough for life to evolve on any planets that may otherwise be suitable.
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.
