Paul Scott Anderson has had a passion for space exploration that began when he was a child when he watched Carl Sagan’s Cosmos. While in school he was known for his passion for space exploration and astronomy. He started his blog The Meridiani Journal in 2005, which was a chronicle of planetary exploration. In 2015, the blog was renamed as Planetaria. While interested in all aspects of space exploration, his primary passion is planetary science. In 2011, he started writing about space on a freelance basis, and now currently writes for AmericaSpace and Futurism (part of Vocal). He has also written for Universe Today and SpaceFlight Insider, and has also been published in The Mars Quarterly and has done supplementary writing for the well-known iOS app Exoplanet for iPhone and iPad.
For the first time, astronomers have detected a planet orbiting a white dwarf star. If further confirmed, the discovery shows that some planets could survive the destruction of their sun-like stars, and some might even remain potentially habitable.
Astronomers used a radio telescope in Australia to search for artificial radio signals among 10 million stars. The search came up empty. But, they say, that’s not bad news for those hoping to find intelligent extraterrestrials.
Astronomers say the nearby red dwarf star Gliese 887 appears to have more dangerous flare activity than first believed. This could make life tough – but maybe not impossible – on its family of super-Earth planets.
A new map created by a Reddit user – based on what we know about the highs and lows on Venus’ surface – shows what this neighboring, cloud-shrouded, blazing hot planet might look like with oceans. Wow!
Cracks in Europa’s surface indicate the moon’s outer ice shell has shifted by as much as 70 degrees over the past several million years. It’s the kind of movement you’d expect from a planetary crust floating on a subsurface ocean.
FRB 121102 is one of the few known repeating fast radio bursts, and astronomers are trying to use this new period of activity to understand it better. Some predict the current active phase should end sometime between August 31 and September 9. Will it?
A new study suggests there are more rogue, free-floating planets – unconnected to any star – than stars in our Milky Way galaxy. NASA’s upcoming Nancy Grace Roman Space Telescope is expected to begin finding hundreds of them.
