Is there life on Venus? Specifically, its atmosphere? Researchers in the US and UK make the case for ammonia, phosphine and other biological anomalies on Venus.
For the 1st time, the Webb telescope has analyzed the atmosphere of a distant exoplanet. It probed the atmosphere of Saturn-sized WASP-39b in fantastic detail.
An international team of researchers has released a new study of "polluted" white dwarf stars showing that stars and planets likely form simultaneously.
NASA's MAVEN spacecraft has, for the 1st time, observed two kinds of auroras in Mars' atmosphere at the same time. A massive solar storm caused the light show.
Paul Scott Anderson has had a passion for space exploration that began when he was a child when he watched Carl Sagan’s Cosmos. He studied English, writing, art and computer/publication design in high school and college. He later started his blog The Meridiani Journal in 2005, which was later renamed Planetaria. He also later started the blog Fermi Paradoxica, about the search for life elsewhere in the universe.
While interested in all aspects of space exploration, his primary passion is planetary science and SETI. In 2011, he started writing about space on a freelance basis with Universe Today. He has also written for SpaceFlight Insider and AmericaSpace and has also been published in The Mars Quarterly. He also did some supplementary writing for the iOS app Exoplanet.
He has been writing for EarthSky since 2018, and also assists with proofing and social media.
