A new study of seismic data from marsquakes shows that Mars' interior is lumpy. The debris, deep in the mantle, came from large impacts billions of years ago.
Researchers at UC Santa Cruz developed a new model to study steam world exoplanets, or sub-Neptunes, with hot steamy atmospheres and layers of exotic water.
A new study proposes a novel idea for how to find aliens: Look for their deep space communications when their planets are in alignment, as seen from Earth.
A new study suggests that particles of dark matter in exoplanets could form tiny black holes, which would eventually turn entire planets into black holes.
Is there an atmosphere on TRAPPIST-1 d? New observations from Webb suggest that if there is, it might be more like Mars or Venus. Or it might not exist at all.
Giant free-floating planets drift in space with no stars. New observations from the Webb telescope suggest they could have their own planets orbiting them.
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.
