Black holes, dark matter, gravitational waves and exoplanets: find out how astronomy is unlocking the secrets of the Universe.
If we ever build a Project Hail Mary spaceship, these are the worlds we should visit to find alien life and save Earth
Scientists pinpoint nearly 50 planets where we're most likely to find life
We may have been wrong about why Mars is red this whole time, and the answer relates to life beyond Earth
New study reveals an alternate reason as to why the Red Planet is red
This is how high you would be able to jump on other planets

Alien spaceship warp-drives could be found by looking for ripples in spacetime, say scientists
Warp-drive technology may be science fiction, but understanding it can teach us a lot about the Universe.
Think black holes are black? They're some of the brightest objects in the Universe. Here's why
If black holes are black, how can they give off light?
Hubble has seen a 'strange' comet cracking open over Earth – completely by accident
The Hubble Space Telescope observed comet C/2025 K1 (ATLAS) breaking up, but caught its disintegration completely by accident.
Some say Earth's radiation belts mean human spaceflight is impossible. Here's why they're wrong
The science of the Van Allen Belts.
Ireland from space
A selection of images of the Emerald Isle from Earth orbit.
Alien life could emerge on the moons of rogue planets wandering the cosmos. Have we just widened the scope for life beyond Earth?
Life might not need a stable orbit and host star after all
White holes explained
We've all heard of black holes. But what about white holes? Could they really exist?
What would the James Webb Space Telescope look like if you saw it in space? This space mission found out
Clever calculations by two astronomers enabled Gaia to capture an image of Webb in space.
"It went completely bonkers..." Astronomers witness two planets colliding around a distant star
"If we can observe more moments like this elsewhere in the Galaxy, it will teach us lots about the formation of our world."
Earth, our home, is incredibly special. It's the only planet known to support life
Our average star the Sun has a unique selling point: it is the only star we know of to host a planet that has life on its surface.
There's an enormous void of nothingness in our Universe. And scientists found it by accident
The Boötes void spans an area 330 million lightyears across but contains very few galaxies, making it the largest void in the known Universe.
This is how many Earths could fit in the Sun
How big is Earth compared to the Sun, and how many times would our planet squish into the space occupied by our host star?
9 of the biggest mysteries in the Universe
Cosmic quandaries and mysterious secrets about space that remain as yet unsolved.
These spinning stars are the lighthouses of the Universe, and one spoonful of them would weigh five billion tonnes
Everything you need to know about pulsars and how these spinning neutron stars were discovered.
This is light from the birth of the Universe. It's called the Cosmic Microwave Background, and it's mind-boggling
A clearer picture of the early Universe is emerging thanks to studies of the Big Bang’s afterglow
Does a beam of light travel forever, or will it eventually run out? Here's what the science says
Our Sun and its twins fled the centre of the Galaxy 4 billion years ago. Otherwise, life may never have emerged on Earth
Our Sun was part of a mass migration that could have helped life emerge on Earth
These are the most common planets in the Galaxy. Scientists have finally worked out where they come from
Super-Earths and sub-Neptunes are everywhere – now we finally know how they’re made
We may be about to see an asteroid-mining gold rush. But here's why it could be a very bad idea
We examine the scramble to harvest metals from asteroids – and why we should think twice about it
A scientist looked at 'little red dots' in the early Universe and found a black hole that shouldn't exist
The mystery of ‘little red dots’ just got deeper, as a galaxy hiding an overmassive black hole hints at a whole population of cosmic Jekyll and Hydes
An enormous brain in a jar? NASA's best space telescope just saw something really weird...
