Egg-shaped galaxies may be aligned to the black holes at their hearts, astronomers find
New analysis of radio telescope data links the shape of galaxies to the supermassive black holes they host.
New research shows most space rocks crashing into Earth come from a single source
Two new studies show that the majority of meteorites originate from just one family of asteroids between Mars and Jupiter.
Daylight saving is about to start. But why do the days get longer?
Earth’s tilt means the Sun both rises earlier and sets later as we head towards summer.
Earth is getting a tiny new mini-moon. It won’t be the first (or the last)
A large space rock will be temporarily captured by Earth’s gravity throughout October and November.
New measurements reveal the enormous halos that shroud all galaxies in the universe
Today we’re able to finally reveal the first detailed picture of the gas shroud around a galaxy, extending 100,000 light years out into ‘empty’ space.
Supermoons are boring – here are 5 things in the sky worth your time
What’s so special about a supermoon? Hardly anything. There are better things to observe in the night sky, according to a professional astronomer.
What happens when matter is squashed to the brink of collapse? We weighed a neutron star to help NASA find out
Neutron stars contain some of the universe’s most exotic states of matter – but there’s no easy way to peek inside.
Look up! A once-in-a-lifetime explosion is about to create a ‘new’ star in the sky
Astronomers and stargazers around the world are excited to witness a rare event that only happens once every 80 years – a recurrent nova.
We mapped a massive explosion in space, showing how galaxies ‘pollute’ the cosmos
When astronomers focused on the galaxy NGC 4383, they didn’t expect the data to be so spectacular. This is the first detailed map of gas flowing from this galaxy as stars burst within.
We saw one of the most powerful magnets in the Universe come to life – and our theories can’t quite explain it
Astronomers caught the bizarre ‘awakening’ of an incredibly rare magnetic star.
Earth, the Sun and a bike wheel: why your high-school textbook was wrong about the shape of Earth’s orbit
Textbooks often show Earth’s orbit around the Sun as an almost egg-shaped ellipse. The real story is very different.
Planet cannibalism is common, says cosmic ‘twin study’
The largest study yet of ‘twin stars’ shows planetary orbits may be less stable than we thought.
New evidence for an unexpected player in Earth’s multimillion-year climate cycles: the planet Mars
Deep-sea sediments show how the changing orbits of Earth and Mars are linked to past global warming and the speeding up of deep-ocean eddies.
What ended the ‘dark ages’ in the early universe? New Webb data just brought us closer to solving the mystery
With the help of a magnifying glass 4 million lightyears wide, astronomers may have solved the riddle of what burned away the hydrogen fog that pervaded the early universe.
The brightest object in the universe is a black hole that eats a star a day
The black hole J0529-4351 is 500 trillion times brighter than the Sun.
