Best Observational Evidence of First Generation Stars in the Universe. VLT discovers CR7, the brightest distant galaxy, and signs of Population III stars

Astronomers using ESO’s Very Large Telescope have discovered by far the brightest galaxy yet found in the early Universe and found strong evidence that examples of the first generation of stars lurk within it. These massive, brilliant, and previously purely theoretical objects were the creators of the first heavy elements in history — the elements necessary to forge the stars around us today, the planets that orbit them, and life as we know it. The newly found galaxy, labelled CR7, is three times brighter than the brightest distant galaxy known up to now.

The galaxy is at 12.9 billion light years from the Earth, seen at an epoch where the Universe was just 800 million years young.
