Hubble has peered back into the far-ancient past and spotted a tiny galaxy of blue stars, possibly the oldest ever seen, researchers reported in the journal Nature. In images, it's underwhelming ...

Nestled within a tiny red galaxy, it dates back 13 billion years -- just 500 million years before the Big Bang -- and shows ...

According to the latest analysis, we could soon be looking at images of the oldest galaxy ever identified, thanks to NASA's James Webb Space Telescope.

But just because the four newly discovered galaxies are the oldest ones found to date by no means proves they are the oldest ones period.

Astrophysicists at Caltech say they’ve detected the oldest, most distant galaxy known so far. It’s 13.2 billion years old — just over half a billion years younger than the universe itself ...

Astronomers reanalyzed the chemical composition of three stars in the Milky Way's halo and found that they are between 12 and 13 billion years old. They may have also been stolen from other galaxies.

Galaxies as orderly as the Milky Way weren't supposed to exist more than 10 billion years ago. Now astronomers have found one in the first billion years of the universe.

Astronomers have discovered the universe's most ancient spiral galaxy yet, a cosmic structure that dates back roughly 10.7 billion years ...

Astronomers have identified the oldest star in our galaxy that is accreting debris from orbiting planetesimals, making it one of the oldest rocky and icy planetary systems discovered in the Milky Way.

Hubble was pushed to the "limits" to observe the distant galaxy, and NASA researchers believe the telescope will hold the cosmic distance record until the James Webb Space Telescope is launched ...
