Some exoplanets in their stars' habitable zones may be distinctly uninhabitable due to solar flaring. Red dwarfs are known for powerful flaring, and since they're dim and their habitable zones are ...

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

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 ...

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

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.

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

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 ...
