The city of Lexington, Kentucky, appears so tired of being overlooked by humankind that it has sent a formal invitation to the next-best thing: alien life that may or may not exist in a nearby star system.

The Hubble Space Telescope just ogled an exoplanet passing in front of a star in a triple system, revealing the nearby world’s mass.

Exoplanets pushing their atmospheres away may explain a gap in exoplanet masses, according to a team of researchers that recently studied data from NASA’s retired Kepler Space Telescope.

The Webb Space Telescope has revealed a world quite alien compared to our own: WASP-107b, a Neptune-like gas giant that orbits a star some 211 light-years from Earth. Webb has now detected water vapor and sulfur dioxide in the planet’s atmosphere, as well as sand-like silicate clouds.
Comets that bounce around the universe could be delivering the ingredients for life to alien planets

An encouraging new study has found that the interference from exoplanets—planets that orbit stars outside our solar system—has been overestimated in searches for extraterrestrial signals.

The Webb Space Telescope recently turned its focus to a nearby exoplanet and found that it may be a Hycean world, or a world completely covered in a single global ocean, and with a hydrogen atmosphere. And what’s more, the telescope detected a possible detection—note, possible detection, of dimethyl sulfide, a…

Astronomers recently spotted one of the most massive brown dwarfs known, an object between 75 and 90 times the mass of Jupiter with a beyond-scalding dayside temperature of 8,000 K (13,940° Fahrenheit.)
