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 ...

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 grasp of how stars rotate is "insufficient," with implications on our ability to understand the causes of phenomena on the sun like solar flares and coronal mass ejections that cause aurora ...

Scientists have used solar flares from the sun to determine the physics driving powerful and violent 'superflares' on massive stellar bodies that are up to 10,000 times brighter than our star.

A groundbreaking new mission may soon allow scientists to study the sun’s corona with unprecedented clarity. The Moon-Enabled Sun Occultation Mission (MESOM), a proposal from a group of researchers ...

However, solar flares are just the tip of the iceberg in terms of outbursts of energy that stars can emit. A more extreme phenomenon is the "superflare," an explosion that can be tens of thousands ...

Some stars erupt with 'superflares' 10,000 times as powerful as solar flares from the sun. A team of "stellar detectives" are on the case and may now know why some stars are so violent.

Solar flares are classified based on their strength and fall into five designated categories: A, B, C, M and X. An X-class solar flare is the most intense type of solar flare and can produce as ...

"A new study of 56,000 sun-like stars reveals that other stars like ours may experience powerful superflares about once per century, shedding light on the potential for rare but extreme solar ...
