The James Webb Space Telescope has spotted one of the earliest and most distant supernovas, marking the death of a stellar monster 20 times the mass of the sun.

A light echo is created when a star explodes or erupts, flashing light into surrounding clumps of dust and causing them to shine in an ever-expanding pattern.

The James Webb Space Telescope captured photos of one of the earliest supernovas ever seen using infrared technology, and creating a time lapse of the phenomena.

JWST revealed a massive star that ended its life in an explosion when the universe was just a cosmic toddler.

the James Webb Space Telescope's powerful infrared eyes watched as light from a centuries-old supernova illuminated interstellar material, warming it and causing it to glow. "This is going to ...
