The subsurface ocean on Enceladus is stable enough for life, a new study of data from the Cassini mission suggests. Heat flow at both poles provides the clues.
Astronomers have created the 1st 3D temperature map of a distant exoplanet. The planet, WASP-18b, is a scorching ultra-hot Jupiter 400 light-years away.
Astronomers discovered 3 Earth-sized planets in the binary star system TOI-2267. It's the first time where the planets are orbiting each individual star.
Scientists see mysterious transient flashes of light in 1950s sky images from the Palomar Observatory. It was before the 1st satellites. What were they?
Astronomers using the James Webb Space Telescope said they've found evidence of a possible volcanic exomoon orbiting the hot Jupiter exoplanet WASP-39b.
If there are any living microbes on Mars, or even dead ones, the best place to search for them is in ice deposits, a new study from Penn State and Goddard said.
Researchers investigated unusual gullies on Mars that are deeply etched into sand dunes. Blocks of sublimating CO2 ice could create the unearthly features.
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.
