A team of astronomers announced this week that they've detected a possible sign of life on an exoplanet 124 light years away using the James Webb Space Telescope. Even more enticingly, the exoplanet, dubbed K2-12b, was already suspected to be an ocean world. The biosignature is a molecule called dimethyl sulfide. On Earth, it's exclusively produced by phytoplanktons and other microbes. Thus, the authors of the new study, published in The Astrophysical Journal Letters, maintain that the best exp

Humans have been pondering the existence of life beyond Earth since ancient times. In the 1900s, scientists began actively searching for proof. Needless to say, we still haven’t found any. Although it’s only been a number of decades and technology is advancing every day, what if we continue to come up empty-handed? In a study published Monday in The Astronomical Journal, an international team of researchers tackled this question by arguing that what we don’t find can still be deeply informative

Astronomers have spotted four smaller-than-Earth exoplanets orbiting the closest single-star system to us, called Barnard's Star. As detailed in a new paper published in the journal The Astrophysical Journal Letters, an international team of researchers discovered that the star — a small red dwarf star just 16 percent of our own Sun's mass and just under six light-years from Earth in the constellation Ophiuchus — has four tiny and seemingly rocky worlds orbiting it. According to the astronomer

Astronomers have identified four exoplanets orbiting Barnard’s Star, a red dwarf star just 6 light-years away from Earth. No, really, this time it’s for real! We have to emphasize this because astronomers have been “discovering” exoplanets orbiting Barnard’s Star—and then discovering they were wrong—for a century. “Exoplanet” is the technical term for planet-like bodies beyond our solar system, but some scholars use “planet” for simplicity. Now, however, an international research team has conf

Astronomers have uncovered the secrets of an alien atmosphere on an exoplanet far beyond our Solar System, and it’s unlike anything we’ve ever seen before. In a scientific first, an international team of astronomers has 3D mapped the atmosphere of planet WASP-121b, also known as Tylos. Using the European Southern Observatory’s Very Large Telescope (yes, that’s really what it’s called), they identified complex weather patterns and a surprising chemical composition. Their study, published in an e
