A SETI search of 1,300 stars for optical alien signals has found something odd: two fast, identical starlight pulses from a sunlike star 100 light-years away.
Astronomers have seen convective clouds in the northern regions of Saturn's moon Titan for the 1st time. The methane rains replenish Titan's lakes and seas.
The Eagle nebula - aka Messier 16 or M16 - is home to several well-known cosmic structures, including the stunning Pillars of Creation and Stellar Spire.
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.
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.
