Feel like visiting another star system or dimension? You can do this by traveling through a spacetime portal of a black hole. But you better choose carefully. All black holes are not created equal.

Long ago in the distant past, our entire Universe was microscopic – just like an atom – and obeyed completely different rules of cause and effect.
Perhaps precisely because they are so elusive, Fast Radio Bursts have received a lot of attention in the years since their discovery.
Are there stars other than the Sun that might explode soon close to us? Yes, there are! As long as by ‘soon’ we mean within a million years.
There are lots of places where it’s much, much hotter than the Sun. And the amazing thing is that this heat also makes new atoms - tiny particles that have made their way long ago from stars to us.
Galaxy images and patient records can be equally confusing. Now a team of astrophysicists have realised their methods could help medical professionals.

A podcast all about nothing. From the importance of doing nothing to the ill-effects of time spent in solitary confinement and what nothing means in space.
From a mysterious energy of empty space to parallel universes, cosmology’s view of ‘nothing’ is anything but boring.
New observations show we don’t really understand the universe’s expansion.
Science and art meet on the ‘big screen’ – turning data into visuals at the Lovell Telescope, Jodrell Bank.
The pull created by a black hole is so strong that if you get too close to one – even if you are travelling away from it at the fastest speed it is possible to go – you will never be able escape.
To answer this tricky question, we have to look back in time to when the Earth was born, 4.5 billion years ago.
Pretty much as soon as we understood what galaxies were, we realised they are all moving away from each other. And the ones that are further away are moving faster. In short, the universe is expanding.
People long assumed all the elements we see now were created during the Big Bang. But on May 2, 1952, an astronomer reported spotting new elements coming from an old star and changed our origin story.
The famous cosmologist was closely identified with black holes due to his revolutionary theoretical work explaining some of their mysterious properties.
Stephen Hawking inspired people with his work on black holes and other mysteries of the universe. Many were quick to pay tribute to the theoretical physicist who died today in the UK, aged 76.
The precious metal is literally extra-terrestrial, produced in the heart of the stars. How and under what conditions? Scientists know more thanks to a double astrophysical observation.
Deep underground, scientists research subatomic particles from space in a bid to understand the building blocks of our universe.
Cosmologists are heading back to their chalkboards as the experiments designed to figure out what this unknown 84 percent of our universe actually is come up empty.
A LIGO team member describes how the detection of a gravitational wave from a new source – merging neutron stars – vaults astronomy into a new era of ‘multi-messenger’ observations.
