A gas giant planet called WD 1856b, orbiting the burned-out core of a dead, sun-like star. “It was unlike any other exoplanet ...

Astronomers have found strong evidence of a giant gas planet orbiting a star in a solar system close to our own sun. Four light-years away from Earth, the Alpha Centauri triple-star system has long ...

Gas giants are large planets mostly composed of helium and/or hydrogen. Although these planets have dense cores, they don't have hard surfaces. Jupiter and Saturn are the gas giants in our solar ...

Since the first discovery of planets beyond the solar system in 1995, more than 6,000 exoplanets have been identified. Many of these planets have properties that differ significantly from the eight ...

Astronomers just discovered a gas giant on its way to becoming a hot Jupiter — and it’s extremely weird. An exoplanet on a twisted, backwards orbit may offer clues about how hot Jupiters (giant gas ...

Astronomers using ALMA have uncovered how gas and dust in planet-forming disks evolve separately an insight that reshapes our understanding of how different types of planets form. While dust lingers, ...

An exoplanet infamous for its deadly weather has been hiding another bizarre feature—it reeks of rotten eggs, according to a new Johns Hopkins University study of data from the James Webb Space ...

Rogue planets may be more common than we thought, and they may form alone in the void in the same way stars do, suggests a recent study. We think we know how the universe is structured: Moons orbit ...

The birthplaces of planets are disks made out of gas and dust. Astronomers study these so-called protoplanetary disks to understand the processes of planet formation. Beautiful images of disks made ...
