Astronomers explore the hypothetical world of exomoon expulsion
Moons ejected from orbits around gas giant exoplanets could explain several astronomical mysteries, an international team of astronomers suggests
Deep Space
Hubble spots a strange thin disc at the core of a nearby galaxy
The disc orbits a black hole 250 times the mass of our Sun and it speeds material up to unimaginable speeds
Deep Space
Astronomers watch on as two black hole behemoths get ready for a collision
The titanic duo can help astronomers predict when the historic first detection of the background ‘hum’ of gravitational waves from supermassive black holes will be made
Deep Space
Cold hydrogen could have stopped Milky Way’s star formation
For the first time ionised hydrogen has been detected at the lowest frequency ever towards the centre of our galaxy
Deep Space
Solved! How the universe’s biggest stars become massive
Astronomers have obtained the first detailed face-on view of a gaseous disc feeding the growth of a massive baby star
Deep Space
Astronomers uncover new way to measure space’s expansion
Using National Science Foundation (NSF) radio telescopes, we may now have resolved an outstanding question about the cosmos
Deep Space
What would happen if a planet crashed into a neutron star?
We take a look at the answer to this intriguing question
Deep Space
Hubble and Spitzer team up to reveal the exoplanet’s atmosphere 97 light years away
Atmospheric analysis of Gilese 3470 b shows it be unlike any planet seen in our Solar System
Deep Space
What gives a star its colour?
Find out why stars come in different colours
Deep Space
Streams of cool gas spiral into young galaxies to fuel the birth of stars
Astronomers have long sought-after finer details of this cosmic web to explain the incredible rate of star formation
Deep Space
Astronomers decipher the mystery of ancient supermassive black holes
When the Universe was young, there were a large amount of supermassive black holes for which astronomers could not understand where they came from
Deep Space
Astronomers hope to solve interstellar mystery with the recent detection of “tiny electrically-charged molecules”
This molecule, referred to as “Buckyballs”, consists of 60 carbon atoms arranged in the shape of a football (soccer ball)
Deep Space
Gas ‘flows like honey’ as it travels through galaxy clusters
Astronomers can’t recreate this environment on Earth, so they rely on studying these cosmic laboratories with NASA’s Chandra X-ray Observatory
Deep Space
What happens when a star’s fuel runs out?
We find out what happens when a star uses up all of its fuel
Deep Space
Large radio telescope finds the earliest example of galaxies merging
Two galaxies have been seen merging 13 billion years ago, less than a billion years after the Universe was born
Deep Space
Where do the Universe’s heaviest elements come from?
The answer is not a neutron star or black hole collision, as many astronomers have believed for a long time
Deep Space
A dwarf galaxy 3,000 light years away is forming stars at an unusually incredible rate
More unusually for its size, ESO 495-21 could have a supermassive black hole hiding at its core
Deep Space
What happens when a giant star meets a smaller star?
Does one devour the other, or do they both co-exist? Find out the answer when stellar giants collide
Deep Space
A ring of cool, interstellar gas was detected around the Milky Way’s central black hole
By imaging this cool disk of gas rotate around the supermassive black hole, astronomers can watch how the accretion process unfolds
