Astronomers have listened to a nearby star's music - subtle interior vibrations - to learn more about how stars' rotation speed slows down as they age.
Does the nearby galaxy Messier 83 have a supermassive black hole in its heart? NASA's Webb space telescope has found tantalizing new clues that suggest it does.
Using a new technique, astronomers have discovered a huge molecular cloud in space near our solar system, dubbed Eos. It had remained undetected until now.
The discovery of a super-Earth orbiting farther from its star than Saturn orbits the sun suggests that super-Earth exoplanets are common in our galaxy.
Did it rain on ancient Mars? A new study suggests that heavy precipitation - rain or snow - helped form rivers that fed into lakes billions of years ago.
To search for alien life - even exotic life beyond our imagination - a new study suggests looking for "patterns of energy" instead of just organic molecules.
The Curiosity rover has found deposits of carbonates on Mars. It's evidence for an ancient carbon cycle and could explain what happened to Mars' atmosphere.
New observations by the Webb Space Telescope have reignited the debate about possible life on K2-18b, a potentially habitable exoplanet 124 light-years away.
Astronomers have discovered a Tatooine world that orbits 2 brown dwarfs (failed stars). But strangely, the planet orbits the brown dwarfs at a 90 degree angle.
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.
