Gliese 523b (GJ 523b) is a young, ultra-dense planet that orbits almost perpendicular to its star’s spin, according to a team of U.S. astronomers. An...

Astronomers from New Mexico State University, Nicolaus Copernicus Astronomical Center and CUNY Borough of Manhattan Community College propose that the...

New simulations suggest supernova explosions of the Universe’s first stars scattered the ingredients for rocky planets only 100 million years after the...

Astronomers using ESO’s Very Large Telescope (VLT) have discovered a gas giant around a brown dwarf in the stellar system CD-35 2722. The discovery blurs...

Using spectral data from the Magellan Clay telescope at Las Campanas Observatory, astronomers detected helium escaping from LHS 1140b, a rocky exoplanet...

A new analysis suggests the four sub-Earth exoplanets orbiting Barnard’s star — the Sun’s nearest single-star neighbor — are likely packed...

Named Beta Pictoris d, the newly-discovered world is 100 times fainter than Beta Pictoris b — the first planet discovered around the A5-type star...

Using the upgraded GRAVITY+ instrument on ESO’s Very Large Telescope Interferometer (VLTI), astronomers have measured the ratio of carbon isotopes in...

Astronomers using the NASA/ESA/CSA James Webb Space Telescope have analyzed the atmosphere of a massive exoplanet orbiting the white dwarf WD 1856+534....

Astronomers have discovered a rocky exoplanet about twice Earth’s size just 25 light-years away, orbiting in the habitable zone of its parent star, Gliese...

ESA’s Euclid space telescope mapped more than 60 million stars in the Milky Way’s central bulge, producing the largest high-resolution visible-light...

Two newly discovered exoplanets, TOI-791b and TOI-791c, are as large as Jupiter but have densities lower than cotton candy, giving astronomers a rare glimpse...

HD 80606b has one of the most extreme orbits of any known exoplanet and the NASA/ESA/CSA James Webb Space Telescope just caught it getting flash-fried...

The giant planet’s bow shock isn’t just deflecting the solar wind, it’s acting as a powerful particle accelerator, firing electrons to relativistic...

By tracking fierce winds racing through the atmospheres of seven ultra-hot Jupiters, astronomers have uncovered the strongest evidence yet that magnetic...

Using spectral data from the Near-Infrared Spectrograph (NIRSpec) onboard the NASA/ESA/CSA James Webb Space Telescope, astronomers analyzed the atmosphere...

The existence of circumbinary planets — exoplanets that orbit binary stars — has only been firmly established over the past 15 years. Observations...

Using the NASA/ESA/CSA James Webb Space Telescope, astronomers have detected water-ice clouds swirling through the atmosphere of Epsilon Indi Ab, a cold...

The TOI-201 system consists of a super-Earth, a warm Jupiter, and a more massive brown dwarf at 5.8-, 53-, and 2,900-day orbital periods, respectively. An...

A new ‘agnostic biosignature’ method searches for patterns across exoplanets, suggesting alien life could be detected by how it spreads and reshapes...
