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.
According to a new study by astronomers, based on data from the Kepler Space Telescope, 1 in 4 sunlike stars should have a planet that’s approximately Earth-sized, orbiting in the star’s habitable zone.
On Earth, methane gas is often associated with microbial life. Scientists find methane in Mars’ atmosphere, too. Could it be life-related? We still don’t know, but a new study shows wind erosion is likely not the cause.
For the first time, heavy metal gases like magnesium and iron have been detected floating away from an exoplanet, a planet orbiting a distant sun. Why? Because the planet – which is about as big as Jupiter – is orbiting perilously close to its star.
It’s likely Mars was once a water world with rivers, lakes and maybe even an ocean. New research lends support to the possibility that an asteroid slammed into Mars’ ocean 3.5 billion years ago, creating a vast tsunami.
Io’s volcanoes have fascinated scientists since the Voyager 1 spacecraft first discovered them nearly 40 years ago. Now a comprehensive new report – based on ground-based studies – unveils new mysteries about the most volcanically active world in our solar system.
This short video, just over a minute long, takes you on a journey from 1991, when no exoplanets were known, to today’s 4,003+ known exoplanets. Why the plus? According to the NASA Exoplanet Archive, the number of known exoplanets has already jumped up to 4,031 and counting!
Duck-billed dinosaurs – hadrosaurids – were common 80 million years ago. Now scientists have discovered a complete skull of a previously unknown species of hadrosaurid, which sported unusual skull and face features.
For the last few decades, the search for extraterrestrial intelligence has focused on detecting radio signals. But a new collaboration between Breakthrough Listen and VERITAS will focus on looking for laser-like flashes of light.
