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.
Researchers in the U.K. said in a new study that 'bouncing comets' in some planetary systems could deliver prebiotic molecules needed for life to young planets.
Researchers have found evidence of glaciers on Mercury. They are composed of salt, not ice, and could potentially create habitable niches for microorganisms.
A new study from an international team of researchers says that 2 huge blobs inside Earth came from the collision with the planet Theia billions of years ago.
NASA's Juno spacecraft has found salts and organics on Jupiter's largest moon, Ganymede. They suggest that watery brines came up to the surface from deep below.
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.
