Astronomers detect 'whirlpool' movement in earliest galaxies
A Cambridge University-led study has discovered swirling gas in some of the earliest galaxies that formed soon after the Big Bang. Using Chile-based telescopes, astronomers probed star-forming galaxies that appeared over 13 billion years ago and found they spun like a whirlpool, like the Milky Way. Light from such distant objects allows astronomers to understand the history of the Universe.
