NASA's Webb telescope has mapped the weather on WASP-43 b, a hot Jupiter exoplanet 283 light-years away. It's blistering hot with 5,000-mile-per-hour winds.
NASA's Webb telescope looked at the sub-Neptune exoplanet K2-18 b. It found methane, carbon dioxide, a possible ocean, and even ... maybe ... a biosignature.
New experiments show that methane on Mars, in Gale crater, may seep out of the ground when hard crusts of perchlorate salt temporarily warm up and weaken.
For the 1st time, astronomers have found glowing methane on a brown dwarf. The researchers say that auroras in the brown dwarf's atmosphere may cause it.
A new study reveals Io's volcanoes have been erupting for billions of years, ever since the small moon of Jupiter 1st formed along with our solar system.
NASA's Perseverance rover sampled an unusual Mars rock called Bunsen Peak. It is rich in carbonate and silica and likely came from an ancient lakeshore beach.
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.
