Previous studies of 55 Cancri e haven’t been able to determine whether this super-Earth hosts an atmosphere. A new study settles the question.
Astronomers have discovered a potentially rocky planet around a red dwarf star just 11 light-years away.
Tantalizing new observations hint that there's a lot more going on in the Proxima Centauri system — the one that hosts the exoplanet nearest Earth — than meets the eye.
Researchers have found that a football-shaped, ultra-hot gas giant that’s being devoured by its host star is also one of the least reflective exoplanets ever found.
Researchers have found strong evidence of titanium oxide in the atmosphere of a hot giant planet, adding new insights to the complex motions of these planets’ extreme atmospheres.
Astronomers have used an innovative technique to discover four super-Earth-size planet candidates orbiting Tau Ceti, a Sun-like star 12 light-years away.
Astronomers have found one of the best exomoon candidates in data collected by the Kepler spacecraft.
A new study suggests that the seven-planet dwarf star could be much older than the Sun.
Matching theory to observation often requires creative detective work. In a new study, scientists have used a clever test to reveal clues about the birth of speedy, Earth-sized planets.
A new study finds that rogue planets — those floating free in the galaxy, unbound to any star — are not as plentiful as we once thought.
Astronomers have potentially detected a stratosphere in the atmosphere of a hot Jupiter.
An object previously identified as a free-floating, large Jupiter analog turns out to be two objects — each with the mass of a few Jupiters. This system is the lowest-mass binary we’ve ever discovered.
Direct imaging of exoplanets was once only possible for the brightest of planets orbiting the dimmest of stars — but new observations of the Jupiter-like exoplanet 51 Eridani b provide tantalizing clues about its atmosphere.
The most comprehensive and detailed exoplanet catalog released yet marks the end of an era for Kepler, the planet-hunting telescope.
Astronomers announce the discovery of bloated gas giant KELT-9b, the hottest "hot Jupiter" exoplanet known orbiting a short-lived massive star.
The possible discovery of a massive ringed planet in Orion needs confirmation — and amateur astronomers can help.
Astronomers have confirmed the existence of the seventh planet around the ultracool dwarf star TRAPPIST-1.
Astronomers have detected water in the cloud-free skies of "warm Neptune" HAT-P-26b, a clue in the larger mystery of how these planets formed.
Astronomers have discovered an "iceball Earth" orbiting a star 13,000 light-years away. Multiple eyes on the sky have revealed some of this world's secrets.
The MEarth exoplanet survey nabs LHS 1140 b, a rocky planet transiting its host star just 41 light-years distant.
The star with seven exoplanets puts out enough high-energy radiation to tear away the inner planets’ atmospheres in a few billion years.
Hankering to discover new solar systems or understand our own? These citizen science projects and public data troves will help you fill your free time.
Astronomers have found seven Earth-sized planets around a cool red dwarf, all of which have the potential for liquid surface water.
A unique method reveals the influence of a planet within the stellar disk around TW Hydrae.
Astronomers suspect the Sun’s closest stellar neighbor desiccated its potentially rocky exoplanet, destroying the planet’s chances for habitability.
