What a new map of the universe tells us about dark matter

We still can't see the dark matter thought to make up about a quarter of the universe, but at least now we have a map of its structure.

Curious Kids: what started the Big Bang?

What caused the Big Bang is still a mystery. And that's just one of the many unanswered questions, in spite of everything we do know about the birth of the Universe.

Curious Kids: Does space go on forever?

People used to think that when they looked up at the night sky, they were seeing all of space. Then American astronomer Edwin Hubble found out something so amazing, NASA named a telescope after him.

Don’t panic, but the universe is slowly dying

Our universe's most exciting days are well behind us, with new research showing the universe is now slowly but surely dying.

Explainer: what are fundamental particles?

Subatomic particles have shaped and continue to shape our universe but despite perfect predictions by physicists, the theory about unseen particles is still wrong.

Hidden in plain sight: the Milky Way’s new companions

Several dwarf galaxies have been discovered close to our own Milky Way and are adding to our understanding of how galaxies form. But why haven't astronomers seen them before?

Unlocking the mystery of the first billion years of the universe

More than 100 million years has been wiped off the age of the first stars but there is still the question of what happened in the first billion years of the universe. Earlier this month the European Space…

Gravitational wave discovery still clouded by galactic dust

One of this century’s greatest potential discoveries concerning the origins of the universe has now fallen to galactic dust. That’s according to a new joint-analysis of all the existing data – including…

Has dust clouded the discovery of gravitational waves?

It’s almost three months since a team of scientists announced it had detected polarised light from the afterglow of the Big Bang. But questions are still being asked about whether cosmic dust may have…

First hints of gravitational waves in the Big Bang’s afterglow

Scientists at the Harvard-Smithsonian Centre for Astrophysics in the US have announced overnight what they believe is the indirect detection of gravitational waves in the afterglow of the Big Bang. The…
