We found a mysterious flashing radio signal from near the centre of the galaxy

In early 2020, we detected an unusual radio signal coming from somewhere near the centre of our galaxy. The signal blinked on and off, growing 100 times brighter and dimmer over time. What’s more, the radio waves in the signal had an uncommon “circular polarisation”, which means the electric field in the…

Galactic Archaeology and Modeling the Milky Way

Researchers have created a model of the evolution of the Milky Way which explains how key chemical distributions in the galaxy’s stars came to be. One of the biggest questions in astronomy is related to how our home galaxy, the Milky Way, came to be in its current state. Whilst…

Stunning images of ‘galactic fireworks’ hold the secrets of how stars form

Galaxies are unfathomably huge, dynamic beasts made up of stars that burst into and out of life in cosmic blinks of an eye. Yet we’ve barely been able to observe the mysterious life cycles of galaxies beyond our own. Now, spectacular images of galaxies just next door to the Milky Way, captured…

Detailed cross-section of another galaxy reveals surprising similarities to our home

The first detailed cross-section of a galaxy broadly similar to the Milky Way, published today, reveals that our galaxy evolved gradually, instead of being the result of a violent mash-up. The finding throws the origin story of our home into doubt. Galaxy UGC 10738, seen edge-on through the European Southern…

5 twinkling galaxies help us uncover the mystery of the Milky Way’s missing matter

We’ve all looked up at night and admired the brightly shining stars. Beyond making a gorgeous spectacle, measuring that light helps us learn about matter in our galaxy, the Milky Way. When astronomers add up all the ordinary matter detectable around us (such as in galaxies, stars and planets), they…
