A galaxy seems like a hard thing to miss – let alone 39 of them – but that’s exactly what a team of astronomers has just discovered. So where have these countless stars been hiding? About 11.5 billion light-years away, in a part of the light spectrum that’s invisible to many telescopes.

Saturn sports an impressive ring system, but Uranus also has some, although they’re usually too faint to see without a powerful telescope. Striking new images shows these rings in very clear detail thanks to thermal imaging, allowing astronomers to measure their temperature for the first time.

Asteroid 2012 TC4 hasn’t been seen since its last brush with our planet 5 years ago, but astronomers knew it would return in October 2017. Right on cue, the building-sized rock has now emerged from the darkness of space, and its trajectory has been calculated.

As part of its push to probe the secrets of the Alpha Centauri system, the Breakthrough initiatives will fund a hardware upgrade for the Very Large Telescope in Chile, equipping it with new imaging capabilities to better hunt for habitable planets in the region.
