Using data from NASA’s Spitzer Space Telescope, scientists have identified the three fastest-spinning brown dwarfs ever found. More massive than most planets but not quite heavy enough to ignite like stars, brown dwarfs are cosmic in-betweeners. And though they aren’t as well known as stars and planets to most people, they are thought to number in the billions in our galaxy.

An infernally hot, star-hugging 'super-Earth' some 200 light-years away just might offer critical clues to how planets like ours are formed.
January 27, 2021
Astronomers found the first six-star system where all of the stars participate in eclipses, a discovery made by NASA’s Transiting Exoplanet Survey Satellite (TESS). The system is about 1,900 light-years away in the constellation Eridanus.
January 25, 2021
A new study shows the Roman Space Telescope will unveil more extreme planets and planet-like bodies in the heart of the Milky Way galaxy, thanks to their gravitational tug on the stars they orbit.

Precise measurements reveal that the TRAPPIST-1 exoplanets have remarkably similar densities, which provides clues about their composition.
January 13, 2021
A group of "citizen scientists" helped develop a map of brown dwarfs – failed stars – in our corner of the galaxy, providing a fuller picture of our cosmic neighborhood.
January 11, 2021
Years after its detection, astronomers have learned that a planet called KOI-5Ab orbits in a triple-star system with a skewed configuration.
December 10, 2020
An exoplanet in an unlikely orbit around a double star 336 light-years away may offer a clue to a mystery much closer to home: a hypothesized, distant body in our own solar system dubbed "Planet Nine."
November 10, 2020
Among the stunning variety of worlds in our solar system, only Earth is known to host life. But other moons and planets show signs of potential habitability.
