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

During a brief but dramatic chapter in Earth's history about 41,000 years ago, the planet’s magnetic field nearly collapsed. What followed was a cascade of environmental and biological changes ...

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

It is possible to make a material emit more radiation than it absorbs, violating the laws of physics in a way that could make energy-harvesting devices more efficient ...

A fluffy, Jupiter-sized planet may be triggering deadly flares from its star, leading to the slow destruction of its own ...

NASA captured an image of the sun emitting a powerful solar flare that could interfere with technology on Earth.
