A supernova that stayed bright for over three years seemed impossible, but it could be explained if the explosion is running into dense rings of dust and gas
We just found 72 new galaxies in one of the most studied areas of the sky. We can’t see their stars, but they were revealed by the glow of hydrogen gas
The first global “light census” shows that the area affected by artificial lighting is growing by 2.2 per cent every year, posing risks to wildlife and human health
Our first detailed glimpse at ‘Oumuamua, the interstellar asteroid that recently flew by Earth, shows it’s one of the weirdest asteroids we’ve ever seen
A newly discovered nearby world is probably close in size and temperature to Earth. This exoplanet might be able to host life because of its unusually calm star
The collision that produced recent gravitational waves may have left behind the biggest neutron star ever seen. But it might have collapsed into a black hole
An icy comet just hurtled past the sun on a strange path that suggests it came from outside our solar system, making it the first such interloper we've ever spotted
Detecting gravitational waves has given us a new way to observe the universe by listening to ripples in space-time. Here are five of the biggest finds from LIGO
Breakthrough Listen detected more radio pulses from the famous repeating source FRB 121102. They’re higher frequency than previous ones but we still don’t know what causes them
A planet nearly double the size of Jupiter and 900 light years away has a glowing stratosphere and an atmosphere hot enough that iron there exists as a vapour
