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.
White dwarf stars are typically more or less Earth-sized. The planet orbiting white dwarf WDJ0914+1914 appears to be at least twice as big as its star! High intensity radiation from its star is causing this planet to evaporate. Will the same thing happen in our solar system someday?
A new study focuses on the axial tilt of Earthlike exoplanets in binary or double star systems. It boosts hope for complex life elsewhere … although not, these astronomers say, within the star system closest to our sun.
It sounds unbelievable, but a new study from Kagoshima University and the National Astronomical Observatory of Japan says that exoplanets – thousands of them – could be orbiting supermassive black holes.
‘Oumuamua – the weird object that entered our solar system in 2017 and quickly fled back toward interstellar space – might not be an asteroid or comet from a distant solar system, as many believed. It might instead be a “cosmic dust bunny.”
Scientists are still trying to figure out where Mars’ methane comes from. Now there’s a new mystery that might be connected: unusual fluctuations of oxygen in Mars’ atmosphere, detected by the Curiosity rover.
