HIP 67522 b, a Jupiter-sized planet, orbits its star in just 7 days. Its closeness disturbs the star’s magnetic field, triggering stellar flares that scorch the planet’s atmosphere ...

A recent study has uncovered a dramatic interaction between a planet and its parent star that is reshaping our understanding ...

The first ever recorded 'planet with a death wish' orbits so close to its host star that it triggers huge flares of radiation ...

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

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

A research team led by Dr. Shen Jinhua from the Xinjiang Astronomical Observatory (XAO) of the Chinese Academy of Sciences has investigated rapid spatiotemporal vertical electric currents (VECs) ...

An unexpectedly strong solar storm rocked our planet on April 23, 2023, sparking auroras as far south as southern Texas in ...

Solar flares are the most powerful explosions in the solar system the biggest ones can have as much energy as a billion ...

Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth’s atmosphere to physically affect humans on the ground, NASA claims. However, when intense ...

A NASA mission to observe the activity of the solar wind has returned its first images of giant coronal mass ejections (CMEs) ...

It was an X-class flare — the most intense kind, NASA said. Solar flares are essentially "giant explosions on the sun" that send energy, light and high-speed particles into space, according to NASA.
