Hubble Looked as Far Back in Time as it Could, and Still Couldn’t See the First Generation of Stars in the Universe

Posted by in category: space

Astronomers don’t know exactly when the first stars formed in the Universe because they haven’t been observed yet. And now, new observations from the Hubble Space Telescope suggest the first stars and galaxies may have formed even earlier than previously estimated.

Why? We *still* haven’t seen them, even with the best telescope we’ve got, pushed to its limits.

A group of researchers used Hubble to look back in time (and space) as far as it could see, hoping to study these first generation of stars of the early Universe, which are called Population III stars. Hubble peered and squinted back to when the Universe was just 500 million years old – which is thought to be Hubble’s limit — and found no evidence of these very first stars.
