By Will Dunham WASHINGTON (Reuters) -Scientists are tracking a large gas planet experiencing quite a quandary as it orbits ...

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

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 ...

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 ...

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

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.

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

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

The multimillion-dollar experiment that was years in the making comes as the federal government makes broad cuts to science ...
