A faint, ancient flash of light detected by the James Webb Space Telescope (JWST) has broken the record for the most distant stellar explosion ever recorded, revealing a massive star’s demise when the ...

"This observation also demonstrates that we can use Webb to find individual stars when the universe was only 5% of its current age." When you purchase through links on our site, we may earn an ...

The big picture: NASA's James Webb Space Telescope recently managed to capture imagery of the oldest and farthest known supernova explosion – an event that occurred when the universe was just 730 ...
