Exoplanet discovery can help us work out how the Earth will end its days.
Feel like traveling to another dimension? Better choose your black hole wisely.
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.
The South Pole Telescope and BICEP telescopes (pictured above) may discover clues that could teach us if there was something else ‘before’ the Big Bang.

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.
The good thing about space is that – even though it has lots of dangerous stuff floating in it, and lots of exploding stars – it’s so big and empty that it almost doesn’t matter.
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.
The Sun is a star – but it’s not the only one.

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.
Galaxy history revealed by the Hubble Space Telescope.
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.
Nobody knows for sure where black holes lead to.
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.
In fact, some things are slowing the Earth down or could change its spinning in the future.
To answer this tricky question, we have to look back in time to when the Earth was born, 4.5 billion years ago.
About a century ago, we didn’t even know that galaxies existed.
Mai Lam/The Conversation NY-BD-CC
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.
New heavy nuclei are constantly generated in stars and other astronomical bodies.
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.
What goes in doesn’t go out?
The famous cosmologist was closely identified with black holes due to his revolutionary theoretical work explaining some of their mysterious properties.
British theoretical physicist and cosmologist, Professor Stephen Hawking in 2014.
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.
Looking up in the main chamber at SNOLAB’s facility in the Vale Creighton nickel mine in Sudbury, Ont., a giant spherical neutrino sensor array the size of a 10 storey building is used to detect subatomic particles that pass through the earth.
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.
