Our Galaxy Was Walloped by a Neighbour in Its Not-So-Distant Past, New Analysis Suggests

Space is a chaotic, ever-changing place. But that’s not limited to exploding stars and colliding black holes. Even our own Milky Way galaxy could have recently received a massive jolt from which it is still recovering. Read More >>

Incredible New View of the Milky Way Is the Largest Star Map Ever

The European Space Agency’s Gaia spacecraft team has dropped its long-awaited trove of data about 1.7 billion stars. You can see a new visualisation of all those stars in the Milky Way and nearby galaxies above, but you really need to zoom in to appreciate just how much stuff there is in the map. Yes, the specks are stars. Read More >>

12 Incredible New Images of Galaxies and Nebulae from the Hubble Telescope

Look up to the sky with the unaided eye and you’ll see lots of specks and globs that look mostly like stars. On closer inspection, though, some of those dots refuse to resolve, smeared out on the night sky. Read More >>

Dark Matter May Not Solve This Galactic Mystery After All

Physicists would love to find hints of dark matter to explain the parts of the universe we just haven’t been able to figure out. Dark matter would neatly explain the strange behaviours of galaxies and oddly bent light in our universe. But a new paper may have snuffed out dark matter as a candidate for a mystery at the centre of our galaxy. Read More >>

Half of Our Galaxy Might Have Come From Other Galaxies

Any Carl Sagan fan knows you’re made of star stuff. Protons don’t decay into any other particles (as far as we can tell), so you can reliably assume that most bits of you have been around since a second after the Big Bang. But if you’re thinking a little more locally, you might wonder whether the Milky Way formed in its entirety before little ol’ you were made. Read More >>

Finally, an Astrophysics Simulation Even Your Stoner Friend Will Love

The Milky Way isn’t just stars orbiting a black hole—it’s loaded with dust and debris, floating with reckless abandon in the space between solar systems. And like the stuff that accompanies wildfires or windy days in the desert, dust makes it hard to see. Think about that, bro... we’re just like, specks of dust. Read More >>
