Stars from outside the Milky Way seen zooming through the galaxy
3 May 2018
We’ve seen two runaway stars hurtling through the galaxy at more than 700 kilometres per second, and dozens more going so fast they could escape the Milky Way

We see neutrinos from the big bang in the way galaxies cluster
4 April 2018
Just after the big bang, waves of neutrinos and other matter raced across the cosmos. Those neutrinos reached forward in time to dictate where galaxies form now
Dark radiation may fix our broken understanding of the universe
20 March 2018
We have two ways to measure the accelerating expansion of the universe, but they don’t line up. If dark matter gives off radiation, it could make them agree
The sun’s mysteriously hot corona may be due to invisible plasma
13 March 2018
The surface of Saturn's largest moon Titan might be covered in salt-like crystals that could be among the ingredients for nitrogen-based microbes
Dark matter could be produced by twisted gravitational waves
9 February 2018
If gravitational waves – ripples in space time – have a handedness, primordial particles could interact with them to form a dark matter superfluid that spreads through the cosmos
Parallel universes could solve a big problem with black holes
20 December 2017
The black hole firewall paradox has been vexing physicists for years. But if quantum laws lead to the creation of other universes, the headache disappears
Space-time and gravity might be born from the quantum world
18 December 2017
To reconcile quantum mechanics and gravity, a new theory flips the usual script. Space-time and gravity may emerge from quantum effects, not the other way round
Dark energy survives neutron star crash test while rivals fail
20 October 2017
We saw gravitational waves and light at the same moment from a neutron star merger, which means Einstein was right and some alternative theories are dead
Far-off galaxies are firing rare high-energy cosmic rays at us
21 September 2017
The highest energy particles in the universe hit Earth very rarely, so it took 10 years of data to pinpoint their origin. They’re coming from galaxies far, far away
Chinese satellite beats distance record for quantum entanglement
15 June 2017
Entangled photons survived transmission to locations 1200 kilometres apart on Earth, a feat that could kick off the use of quantum satellites for secure communications
