The ‘remarkable’ XRT 200515 cosmic explosion observed by NASA’s Chandra X-ray Observatory

A mysterious, one-off flash of energy has left astronomers puzzled. A research team led by Steven Dillmann of Stanford University was scouring decades-old data from NASA’s Chandra X-ray Observatory when it spotted a powerful but brief blast of X-rays coming from within the Large Magellanic Cloud (LMC), a galaxy that orbits the Milky Way. The X-ray flash, XRT 200515, shone brightly for about ten seconds a little over two decades ago.
