TRAPPIST-1 is a red dwarf star located about 40 light years away that hosts seven Earth-sized rocky planets, with at least three orbiting in the habitable zone where liquid water

The earliest images of 3I/ATLAS, newly uncovered by Michigan State University, reveal how the interstellar object evolved as it traveled through our solar system—and how other distant solar systems might

A new study suggests a habitable past and signs of ancient microbial processes on Mars. Led by NASA and featuring key analysis from Imperial College London, the work has uncovered

A team of researchers, including those at the University of Tokyo, discovered that liquid water once flowed on the asteroid that spawned near-Earth asteroid Ryugu more than a billion years

A blowtorch of seething gases erupting from a volcanically growing monster star has been captured by NASA’s James Webb Space Telescope. Stretching across 8 light-years, the length of the stellar
