Scientists have detected evidence of a colossal explosion in space – five times bigger than anything observed before.
The huge release of energy is thought to have emanated from a supermassive black hole some 390 million light years from Earth.
“I’ve tried to put this explosion into human terms and it’s really, really difficult,” co-author Melanie Johnston-Hollitt told BBC News.
“The best I can do is tell you that if this explosion continued to occur over the 240 million years of the outburst – which it probably didn’t, but anyway – it’d be like setting off 20 billion, billion megaton TNT explosions every thousandth of a second for the entire 240 million years. So that’s incomprehensibly big. Huge.”

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
