Ancient stardust discovery may change what we think about stars

Scientists just came one step closer to understanding the universe. They've found the most distant galaxy ever found that contains cosmic dust. It means we can peer back over 13 billion light years.

The discovery was made by a team from University College London. It provides scientists with a new idea of when the very first stars were 'born' and how the universe expanded.

It was found by the Alma Array in Chile. The youngest and most remote galaxy ever seen by Alma has been dubbed a2744_yd4.

The detection of so much star dust also gives scientists information on when the first supernova exploded.

Astronomers can now probe deeper into a2744_yd4 and similar galaxies, bringing us that much closer to learning how the universe began.
