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

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

The clingy planet orbits so close to its star, it triggers powerful explosions of radiation that eat away at its atmosphere.

Astronomers have spotted an alien planet orbiting so closely to its home star, the planet's magnetic field is triggering ...

A new study has uncovered a connection between solar flares—sudden outbursts of radiation from stars—and short-term weather patterns on distant Earth-like planets.

Our Sun constantly froths with sunspots and solar flares, many larger than our planet, and yet these are dwarfed by Coronal Mass Ejections, such as the Carrington Event of 1859, which would have wiped ...

When HIP 67522 b was discovered, it was the youngest known planet orbiting its star in under 10 days. Astronomers were using ...

Artist's concept of the star HIP 67522 with a flare erupting toward an orbiting planet, HIP 67522 b. A second planet, HIP ...

Solar flares can reshape exoplanet atmospheres within days, affecting temperature, winds, and potential habitability.

Scientists have discovered HIP 67522 b, a planet so close to its star that its orbit disturbs the star’s magnetic field, ...

Learn about new observations that reveal an exoplanet is destroying itself by cuddling up to its host star, in an ...
