  • New stellar streams confirm 'melting pot' history of the galaxy
    on January 10, 2018 at 7:13 pm

    Where do the stars in our Galaxy come from? All the stars we see in the night-time sky belong to our Milky Way galaxy, and while most stars were likely born here, in the Milky Way, many appear to have originated in other galaxies and migrated to our shores. Tell-tale evidence comes from streams of stars created when small galaxies interact with the Milky Way. […]

  • Astronomers detect 'whirlpool' movement in earliest galaxies; swirling gases soon after Big Bang
    on January 10, 2018 at 6:15 pm

    Astronomers have looked back to a time soon after the Big Bang, and have discovered swirling gas in some of the earliest galaxies to have formed in the universe. These 'newborns' -- observed as they appeared nearly 13 billion years ago -- spun like a whirlpool, similar to our own Milky Way. This is the first time that it has been possible to detect movement in galaxies at such an early point in the universe's history. […]

  • Black hole breakthrough: New insight into mysterious jets
    on January 10, 2018 at 4:30 pm
