Most of this activity lacks sufficient punch to harm us… but every now and then, the Sun erupts with a flare powerful enough to do serious damage. And we don't know how often such events occur.

An international research team has now observed a teraelectronvolt gamma-ray flare seven orders of magnitude -- tens of millions of times -- larger than the event horizon, or surface of the black ...

The authors report the first observation of a high-energy gamma-ray flare in over a decade from the supermassive black hole M87, based on nearly simultaneous spectra of the galaxy spanning the ...

These superflares are similar to the solar flares we see emitted from our sun, except much more powerful, releasing thousands of times the energy of a typical solar flare. By comparison ...

In a worst-case scenario, if the flare also spawns a supersize coronal mass ejection that happens to be aimed at Earth, it could cause a violent geomagnetic storm, inducing electric currents that ...

A more extreme phenomenon is the "superflare," an explosion that can be tens of thousands of times more powerful than the "typical" solar flare. One of the most violent solar storms on record was ...

Northern Lights could be incoming midweek after the first powerful X-rated solar flare for many weeks. Satellites in Earth orbit detected an X2.2 class solar flare early on Dec. 8, 2024 ...

The six new Safari backgrounds include two that use iconography from Apple’s web browser in a clever way — much like the new Macintosh wallpapers in macOS Sequoia.
