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.
