Astronomers in Germany say that 2 possible giant exomoons probably don't actually exist. That's disappointing, but there are still some other candidates.
Do the plumes on Enceladus contain evidence of life from the moon's ocean? A new study shows that amino acids could survive and be detectable by spacecraft.
Researchers at Johns Hopkins are simulating haze on water worlds. The haze muddles observations but can also help determine if an exoplanet is habitable.
NASA's James Webb Space Telescope has found molecular building blocks of rocky exoplanets in a region previously thought to be too extreme and hostile.
China's Zhurong rover has found polygonal wedges below the surface in Utopia Planitia on Mars. Freeze-thaw cycles of water and ice likely created the polygons.
The U.S. Space Force wants to track objects near Earth that exhibit 'abnormal observables' and are of 'unknown origin.' Could there be a connection to UAP?
Astronomers using the Hubble Space Telescope measured the exact diameter of a nearby Earth-sized exoplanet. The sizzling world is too hot for life, however.
Scientists say they may have solved the mystery of shrinking exoplanets. Radiation from the cores of less massive sub-Neptunes pushes away their atmospheres.
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.
