Astronomers are surprised by what they're finding out about galaxies that formed in the early days of our universe, now that sensitive telescopes allow direct observation, not the inference of old.
Understanding how the billions of stars in our galaxy formed and evolved is the subject of a huge galactic archaeology project.
A new discovery can help determine where all the stars in the universe's galaxies actually come from.
Astronomers are making new discoveries about our galaxy thanks to a more detailed map of the Milky Way.
What did Isaac Newton, Captain Cook and Eddie Mabo all have in common? Each, in their own way, looked to the heavens to make sense of the world, and the importance of their place in it.
The Gaia catalogue’s incredible precision is only possible due to accurate tracking of Gaia itself from the ground.
