NASA Kepler's Hall of Fame: Small Habitable Zone Exoplanets
Webb's firsts keep coming: Observations of the exoplanet WASP-39 b show fingerprints of atoms and molecules, as well as signs of active chemistry and clouds.
NASA's Webb Reveals an Exoplanet Atmosphere as Never Seen Before
New observations show that a previously identified exoplanet, TOI-1075 b, is among the most massive super-Earths found so far.
Discovery Alert: Massive Planet is a 'Hulk' among Super-Earths
A new study of the "super-Earth" GJ 1252 b shows that the planet likely has a very minimal atmosphere or, possibly, no atmosphere at all.
Discovery Alert: Ultra-hot 'Super-Earth' Could Have No Atmosphere
A newly discovered 'super-Earth' lies in the habitable zone around its star, and appears to be in a prime position for further atmospheric investigation.
Discovery Alert: A Rocky 'Super-Earth' in the Habitable Zone
Webb ushers in a new era of exoplanet science with the first unequivocal detection of carbon dioxide in a planetary atmosphere outside our solar system.
Webb Sees Carbon Dioxide in Exoplanet's Atmosphere
A "super-Earth" discovered using the TESS satellite might be a "water world," though more observations are needed.
Discovery Alert: Intriguing New ‘Super-Earth' Could Get a Closer Look
The James Webb Space Telescope will examine the "lives" of exoplanets, from formation through maturity and eventual demise.
Exoplanets: What NASA Will See with the Webb Telescope
Webb captured the distinct signature of water, along with evidence for clouds and haze, in the atmosphere surrounding a hot, puffy gas giant planet orbiting a distant Sun-like star.
Webb Reveals Steamy Atmosphere of Distant Planet in Detail
Two newly discovered "super-Earths" are rocky worlds – and could be ideal candidates for follow-up atmospheric observations.
Discovery Alert: Two New, Rocky Planets in the Solar Neighborhood
The detection of 30 comets in another solar system – exocomets – could shed light on the formation of our own system of planets.
Discovery Alert: 30 'Exocomets' Orbit a Familiar Star
An international team of astronomers confirms 60 new exoplanets, or planets orbiting other stars; a separate study finds tentative evidence of an “exomoon.”
Discovery Alert: A Flood of New Planets, Plus Hint of an ‘Exomoon'
The count of confirmed exoplanets just ticked past the 5,000 mark, representing a 30-year journey of discovery led by NASA space telescopes.
