Rockfalls and ancient floods could have brought organic materials, and perhaps traces of life, to the region the Rosalind Franklin rover will explore on Mars.
Researchers at Michigan State University have found earlier images of comet 3I/ATLAS not seen before. They provide new clues about this interstellar visitor.
Did early Mars support life? A new study shows how volcanic sulfur on Mars could have kept the planet warm and wet enough to be habitable billions of years ago.
Using the Very Large Telescope, astronomers have seen the growth of baby planet AB Aurigae b. It is still surrounded by dust in its protoplanetary disk.
Scientists have thought the organics in Enceladus' plumes originate in its ocean. A new study suggests at least some of them might be formed by radiation.
Astronomers have identified why the fastest white dwarfs in the Milky Way are so speedy. They are ejected by supernova explosions after 2 white dwarfs collide.
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.
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.
