  A gamma ray burst barely escapes a black holeJul 27, 2021 8:24 PM PDT | url
 
Added 1 new A* page:NASA has detected a "short" gamma ray burst, lasting less than a second—a momentary jet of highly energized particles just barely escaping from a massive star as its core collapsed into a black hole; while brief, "the burst emitted 14 million times the energy released by the entire Milky Way galaxy over the same amount of time."

The original 16" x 6.75" watercolor art for today's new A* page is up for auction on eBay. : )
