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
Deep Space
How many types of black hole are there?
These high-gravity objects come in more flavours than you might expect
Deep Space
Two young exoplanets have been seen clearing a path through its protoplanetary disk
The two exoplanets in the PDS 70 system are sweeping up material as they go to sizes up to 17 times that of Jupiter
Deep Space
A Neptune-sized exoplanet has been discovered in the most unlikely of places
The University of Warwick-led team discovered the exoplanet NGTS-4b, which has been nicknamed ‘The Forbidden Planet’
Deep Space
Astronomers spot a pair of stars rejected and ejected from their host galaxy
The stellar travellers have found themselves about 600,000 light years away from their once-homely galaxy
Deep Space
Can you get a double supernova explosion?
One supernova explosion is enough to pack a punch, but can two go off at the same time?
Deep Space
Why are neutron stars so heavy?
We investigate why this is the case
Deep Space
Astronomers prepare two space-borne tools that will investigate behemoth black holes
Two future ESA missions will provide a unique insight into enormous cosmic collisions with black holes
Deep Space
Astronomers detail the deformation of galaxies as they collide
The collision course between NGC 4485 and NGC 4490 produces a bright and creative form of irregularity
Deep Space
Are planetary nebulae made by supernovae?
We find out if these beautiful structures are made by the titanic explosion of massive stars
Deep Space
Scorching exoplanet has glimpses of exotic metals in its atmosphere
Astronomers have found a host of rare-Earth metals in a the hottest known exoplanet
Deep Space
How are comets made?
We take a look at how these ‘dirty snowballs’ are made
Deep Space
NASA space telescope observes the illumination of primordial galaxies
NASA’s Spitzer space telescope and its infrared capabilities have revealed the details of galaxies born less than a billion years after the Big Bang
Deep Space
More space telescopes could launch leading to even sharper black hole image
Astronomers have proposed constructing a series of space telescopes to image black holes known as the Event Horizon Imager (EHI)
