The James Webb Space Telescope is now delivering what astronomers have chased for decades: a glimpse of the universe’s first generation of stars. By dissecting the light from a tiny, distant galaxy, ...

"We really needed the sensitivity of JWST. We also needed the 100 times magnification from gravitational lensing from a galaxy cluster between us and LAP1-B." When you purchase through links on our ...

For decades, astronomers were only able to study the universe's very first stars using theoretical models. Now, observations from the James Webb Space Telescope (JWST) have revealed what may be the ...

A newly discovered star suggests tiny relic galaxies like Pictor II preserved the chemical material created by the universe's first star explosions and later helped build larger galaxies like the ...

An observation of an ultra-faint galaxy, captured as it was shortly after the Big Bang, indicates the presence of material from the first generation of stars. Because light travels at a finite speed, ...

The first stars were massive, hot, and bright, forming from primordial clumps of hydrogen and helium. They lived fast and died young, but not before producing new elements in their stellar remains ...
