The James Webb Space Telescope has captured an image of a baby, Milky Way-like galaxy that formed more than 13 billion years ago. This "Firefly Sparkle" galaxy could reveal how our own galaxy evolved.
The extraordinary images -- taken with NASA's James Webb Space Telescope -- show a galaxy that glitters with 10 distinct star clusters that formed at different times, much like our own Milky Way.
A new effort to map the rumblings in spacetime caused by enormous black hole collisions paints a surprisingly loud and lopsided picture of ... detector the size of our galaxy.
Taking advantage of a cosmic 'double lens,' astronomers resolved more than 40 individual stars in a galaxy so far away its light dates back to when the universe was only half its present age.
