A century ago this month, a brash astronomer leaked a discovery that opened our view to the cosmic distance scale and the ...

Researchers have discovered a distant disc galaxy that has surprisingly similar characteristics to our own Milky Way, and it could ... such as spiral arms, and they plan to carry out more ...

That might be what astronomers felt when they discovered an evolved galaxy similar to the Milky Way, but lighting up space when the universe was merely 700 million years old. Given that most ...

Current theories suggest that, for a galaxy to be as orderly as our own Milky Way -- a rotating disc with tidy structures like spiral arms -- billions of years of evolution must have elapsed.

“Seeing a galaxy with such similarities to our own Milky Way... challenges our understanding ... are planned to confirm the presence of spiral arms and other advanced structures.

the galaxy also shows hints of spiral arms similar to highly evolved "modern" galaxies like our own Milky Way. The galaxy, designated REBELS-25, is seen as it was just 700 million years after the ...
