The flares may heat up and inflate the planet's atmosphere, which is dominated by hydrogen and helium. Being lashed by these ...

Between the four terrestrial planets–Mercury, Venus, Earth, and Mars–and the distant ice giants of Neptune and Uranus, sit ...

A team of international researchers led by Tomas Stolker in the Netherlands has imaged a young gas giant exoplanet near a 12-million-year-old star. The planet is orbiting a star whose planet formation ...

A giant exoplanet has just been confirmed about 400 light-years from Earth. Named TOI-4465 b, it stands out with a mass six times greater than Jupiter's and unusual orbital characteristics.

Stars often whip their planets with solar winds and radiation, pull them ever closer with gravity and sear them with heat.

A rare Jupiter-sized planet AT2021uey b was found 3,200 light-years away using microlensing, a method based on Einstein's ...

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 ...

Planet-forming disks around young stars lose gas more rapidly than dust, leading to a changing gas-to-dust mass ratio as disks age. Gas disperses quickly in early stages, while dust persists longer.
