Often found around a star or black hole, we find out what an accretion disc is
We take a look at the life so far of one of the greatest physicists of the modern day.
Sophie Allan from the National Space Centre answers this question for us.
Meet the stars that could be responsible for space, time and our existence in the latest issue – out now!
As galaxies prepare to collide, their central black holes become concealed with gas and dust
Some 290 million years ago, a star much like the Sun wandered too close to the central black hole of its galaxy
Data from NASA’s Swift spacecraft, amongst other telescopes, suggest black holes swallow stellar debris in bursts
NASA’s space telescope has found that the black hole ate its last big meal about 6 million years ago
The new finding marks the beginning of the search for quiet black holes
NASA’s Fermi Gamma-ray Space Telescope has identified the farthest gamma-ray blazars, a type of galaxy whose intense emissions are powered by supersized black holes
A mission that will allow astronomers to explore the hidden details of some of the most extreme and exotic objects in the universe has been announced
The mystery extraordinarily brilliant point of light seen in a distant galaxy has been solved
Astronomers have found the shredded remains of a galaxy that passed through a larger galaxy
Physicists have demonstrated that what occurs on the space-time boundary of the two merging objects can be simply explained – at least when black holes collide
A recent study suggests that matter might in fact survive its foray into these space objects and come out the other side
“It is a bit like twisting a spoon in honey”
New research shows that the emission thought to be an afterglow actually originated from a distant galaxy’s core
Is the universe a hologram? The reality of the cosmos could be stranger than you think…
A bizarrely-shaped black hole could cause Einstein’s general theory of relativity, a foundation of modern physics, to break down
A jet from a very distant supermassive black hole being illuminated by the oldest light in the universe has been discovered
