Astronomers probe a mini-Neptune’s atmosphere

Exoplanet Gliese 3470 b fits nicely in size between our solar system's Earth and planet Neptune. Known as a "mini-Neptune," it likely has a rocky core beneath a deep, crushing, hydrogen-helium atmosphere. The analysis of its atmosphere is a first for one of these mid-sized worlds.

Are moons forming around this distant gas giant planet?

After many years of searching, astronomers have finally found what appears to be a circumplanetary disk - that is, a disk of gas and dust - surrounding a young exoplanet. Evidence suggests that moons may be forming there.

Paul Scott Anderson

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.
