Studying exoplanets similar to Venus could aid the search for habitable worlds by teaching us what not to look for in the universe.
An alien planet that orbits a star other than our sun is referred to as an "exoplanet." Learn more about the types of alien planets, including exoplanets and extrasolar planets, and get the latest news.
The atmospheres of gas giant planets across the Milky Way galaxy can be very different from those in the solar system, the James Webb Space Telescope has found.
New measurements by the James Webb Space Telescope found that a rocky exoplanet orbiting a star known as TRAPPIST-1 most likely has no atmosphere.
JWST just peered directly into the atmosphere of the giant exoplanet VHS 1256 b and found a roiling world with turbulent clouds made of silicates, similar to sand here on Earth.
A new method could allow astronomers to assess exoplanets' likely subsurface water stores, aiding the search for worlds capable of supporting life as we know it.
Even quiet red dwarfs are prone to extreme outbursts that put our sun to shame, with significant implications on the search for alien life.
The European Space Agency’s exoplanet-investigating spacecraft CHEOPS has had its mission extended until at least 2026.
The James Webb Space Telescope (JWST) has dazzled us plenty already, but the best is yet to come from the observatory, mission team members say.
A newly discovered distant mini-Neptune planet may possess its own atmosphere, ocean, or a combination of the two, even if they don't last for long.
A real-life version of Spock's home exoplanet in the 'Star Trek' universe has turned out to be nothing more than fiction.
A newly discovered "forbidden" Jupiter-sized planet orbiting a tiny star only four times its size could challenge theories of how gas giants are born.
The mysterious Planet Nine may have up to 20 moons that could be superheated by the hypothetical planet's gravitational pull, making them easy to spot.
The Very Large Telescope in Chile took images of its lightest exoplanet yet after data from two European sky-mapping missions indicated something was tugging at the orbit of a distant young star.
There's apparently a dearth of close-orbiting Neptune-size planets in our galaxy, and two observation techniques are starting to explain why.
Reference The Goldilocks zone or habitable zone is the region around a star where an orbiting planet could host liquid water and, therefore, possibly support life.
A new technique to measure starspots could help test stellar magnetism theories and improve our understanding of habitable zones.
The newfound exoplanet K2-415b is not within the habitable zone of its red dwarf host star, but it could have a neighbor that is.
Gaseous planets close to their star could see their hydrogen atmospheres evaporate, leaving behind helium that could be detected by the James Webb Space Telescope.
The James Webb Space Telescope is imaging the universe in unprecedented detail. Stunning photos showcase the observatory's pioneering work in deep space.
Wolf 1069 b offers a unique opportunity to study a potentially habitable and tidally locked exoplanet.
