A gamma-ray burst, which lit up our galaxy last October, was the "brightest burst" ever seen and a once-in-10,000-year explosion, according to NASA.

The gamma-ray burst, named GRB 221009A, is thought to have caused huge variations in the electrical field of the Earth's ionosphere at a height of around 310 miles above the ground, according to a ...

The gamma-ray, dubbed the "brightest of all time," hit our solar system last fall. Scientists said it was approximately 70 times brighter than any other gamma-ray explosion.

For over a decade, a star system on the verge of unleashing a deadly gamma ray burst appeared to have its guns trained on Earth. The so-called "Death Star," which is also famed for looking like a ...
