Most of the flares you'll hear about in the news are solar flares, or bursts of radiation that emerge from the Sun's lower corona. But other stars experience flares, too, and as they do on the Sun ...

Earlier this year, Earth experienced two geomagnetic storms caused by outbursts of radiation from the Sun, which had an impact on satellites in space and communication systems on the ground.

As the last big solar storm to hit Earth was 165 years ago, we might be in line for another soon, but it is uncertain how similar the sun is to these other stars. While direct measurements of the ...

While our own Sun is a loner, many stars like our Sun orbit similar stars, while a host of other exotic pairings between stars and cosmic orbs pepper the universe. Black holes, for example ...

A superbright Mars is currently visible alongside Regulus, the "Heart of the Lion" star located around 79 light-years from ...

Stars like our own Sun produce “superflares” around once every 100 years ... a decades-long period during the 17th century when very few sunspots were recorded. At the other extreme, solar activity ...

Earth sits within the sun's habitable zone, which means exoplanets — planets that orbit other stars — that also sit in the habitable zone are of particular interest to astronomers. However, different ...

While our Sun prefers to go solo, many other stars are parts of binary systems, with a pair of stars gravitationally bound to each other. In some cases, the stars are far enough apart that planets ...

The closest binary stars to Earth, Alpha Centauri A and B, orbit each other at about 24 times the Earth-Sun distance, or 3.6 billion miles. Suggestions that our Sun could also have a faint ...
