An international team of astronomers reports the discovery of two new exoplanets, a few times more massive than Earth, ...

We tend to think of habitability in terms of individual planets and their potential to host life. But barring outliers like ...

The planet orbits its host star in just 30.5 hours, losing a mass of material roughly equal to Mount Everest each time ...

The president’s proposed budget includes major cuts to NASA — among them, the elimination of funding for the Nancy Grace ...

Astronomers have spotted a small rocky planet that orbits perilously close to its host star disintegrating as its surface is ...

Astronomers have discovered that "super-Earth" planets may exist on wider orbits than previously thought — and this implies these rocky, or "terrestrial," worlds are far more common than was suspected ...

The initial report was based on observations from the powerful James Webb Space Telescope, a collaboration of NASA and its ...

This strange exoplanet, located 140 light-years away from Earth in the constellation Pegasus, appears to be rapidly falling apart. Its blistering host star is so close, the radiation is effectively ...
