For the first time, NASA's James Webb Space Telescope has detected and "weighed" a galaxy that not only existed around 600 million years after the big bang, but is also similar to what our Milky Way.
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have discovered three ultra-massive galaxies -- nearly as massive as our own Milky Way Galaxy - already in place within the first billion years after the Big Bang.
The two earliest and most distant galaxies yet confirmed, dating back to only 300 million years after the Big Bang, have been discovered using NASA's James Webb Space Telescope.
Using the James Webb Space Telescope, researchers observed the birth of some of the youngest galaxies ever witnessed.
