Unraveling the Mystery Behind the Brightest Cosmic Explosion Ever Detected
One of the brightest and most mysterious cosmic explosions ever seen has left astronomers scratching their heads in puzzlement. In June 2023, a burst of gamma rays, the most energetic form of light, was detected by NASA’s Neil Gehrels Swift Observatory. This was soon followed by a wave of X-rays and then a few weeks later by a bright optical flash. But despite the intensity of the event, no radio waves were detected. This has left astronomers wondering how such a powerful explosion could occur without any detectable radio emission.
