Did NASA just observe the brightest burst of all-time? | by Ethan Siegel | Starts With A Bang! | Oct, 2022

Swift’s X-Ray Telescope captured the afterglow of GRB 221009A about an hour after it was first detected. The bright rings form as a result of X-rays scattered from otherwise unobservable dust layers within our galaxy that lie in the direction of the burst. (Credit: NASA/Swift/A.

For most of us, the brightest object we’ll ever see is our Sun.
