Water on giant exoplanets both common and scarce

A new study of the atmospheres of known giant exoplanets suggests that water - an essential ingredient for life - may be common on other worlds in our Milky Way galaxy. At the same, there may be less of it than astronomers once expected.

This white dwarf star has a giant, evaporating planet

White dwarf stars are typically more or less Earth-sized. The planet orbiting white dwarf WDJ0914+1914 appears to be at least twice as big as its star! High intensity radiation from its star is causing this planet to evaporate. Will the same thing happen in our solar system someday?

Does complex life exist elsewhere? Study of exoplanet-tilts boosts hopes

A new study focuses on the axial tilt of Earthlike exoplanets in binary or double star systems. It boosts hope for complex life elsewhere ... although not, these astronomers say, within the star system closest to our sun.

Was ‘Oumuamua a cosmic dust bunny?

'Oumuamua - the weird object that entered our solar system in 2017 and quickly fled back toward interstellar space - might not be an asteroid or comet from a distant solar system, as many believed. It might instead be a "cosmic dust bunny."

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.
