"The discovery of this stream highlights how much is still unknown about the life histories of galaxies, how the hidden universe shapes the realms that we can see." ...

In recent groundbreaking research published in Monthly Notices of the Royal Astronomical Society, scientists from the University of Queensland have provided insights into the likely fate of our galaxy ...

Scientists are peering into the past and uncovering new clues about the early universe. Since light takes a long time to travel through space, they are now able to see how galaxies looked billions of ...

The mystery of galaxies in the early Universe just got even weirder. A team of astronomers has identified a giant spiral galaxy so well-formed that it already has a stable galactic bar; a long, ...

The discovery reinforces established theories about space. There could be many more satellite galaxies orbiting the Milky Way than previously thought or observed, according to astronomers. As many as ...

The SAGA Survey just published three new research articles that provide us with new insights into the uniqueness of our own Milky Way Galaxy after completing the census of 101 satellite systems ...

It’s always amazing, and more than a little humbling, when the universe reminds us that our “common sense” is provincial, ...

So it’s confession time: I’ve been lying to you. I’ve said on many occasions that our Milky Way galaxy has a flat disk (like in this column or this one). But it’s not really flat—not even for a ...

The James Webb Space Telescope may have found dozens of elusive brown dwarfs — strange objects larger than planets but smaller than stars — beyond the Milky Way for the first time ever. When you ...
