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

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 ...

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

Climate change is accelerating due to the buildup of greenhouse gases like CO₂ and methane in our atmosphere. This piece ...

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.

Louisiana is the latest state to redefine natural gas as green energy, even though it’s a fossil fuel that emits ...

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

WASHINGTON, June 25 (Reuters) - In addition to providing a trove of information about the early universe, the James Webb ...

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.

Upgraded ALMA images expose hidden rings and spirals around baby stars, indicating planets begin taking shape mere cosmic ...

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 ...

When a young star forms, a ring of gas and dust called a protoplanetary disk forms around it. Together, the star and the disk are a young solar system, and peering into solar systems much younger than ...
