Astronomers at Australian National University have discovered the oldest known stars, dating from before the Milky Way Galaxy formed, when the Universe was just 300 million years old. Watch the video to learn more. This is a great example of the amazing research discoveries coming from universities and scientific instruments connected to AARNet.
The stars, found near the centre of the Milky Way, are surprisingly pure but contain material from an even earlier star, which died in an enormous explosion called a hypernova.
“These pristine stars are among the oldest surviving stars in the Universe, and certainly the oldest stars we have ever seen,” said Louise Howes, a PhD student at the ANU Research School of Astronomy and Astrophysics and lead author of the study published in the latest issue of Nature.
