Researchers in Europe have successfully tested prototypes of proposed Tumbleweed rovers. The lightweight spherical rovers would use wind to move around on Mars.
Using the Webb space telescope, astronomers have observed auroras on rogue planet SIMP 0136. The giant starless world is about 20 light-years away from Earth.
Researchers might have solved the mystery of Mercury's origin. They say Mercury was formed from a huge grazing collision between 2 rocky bodies of similar mass.
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.
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.
