Searching for life: Could alien life be based on exotic biochemistries unlike Earth's? New research into universal biology and "life as we don't it" says yes.
Scientists have made the most detailed observations of Venus' equatorial nightside winds, which are connected to the planet's runaway greenhouse effect.
Researchers say they have devised a new way of searching for extraterrestrial life on exoplanets using arithmetic-based algorithms called epsilon machines.
Astronomers say they have discovered a 3rd possible planet orbiting the closest star to our sun, Proxima Centauri. It is only about 1/4 of Earth's mass.
For the 1st time ever, astronomers say they have found a solitary, wandering black hole in our galaxy. It is estimated to be 7.1 times the mass of the sun.
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.
