A podcast on darkness: from why it makes us scared, to what kind of nightlife can thrive in the modern city and an update on the hunt for dark matter.
There are two broad ways to measure the expansion of the universe. One is based on the cosmic microwave background, shown here, along with our own galaxy viewed in microwave wavelengths.

The universe is expanding faster than expected, but we don't know what's driving it. Here are a few of the possible explanations, from dark energy to a modification of general relativity.

Something mysterious is pulling our Milky Way through space at a much faster rate than expected. So what could it be?

Astronomers think they may have found evidence within our galaxy of some of the missing matter thought to make up our universe.
Our tendency to see what we want to see is the biggest threat to cosmology.
Confirmation bias, the psychological effect that makes people unconsciously interpret information to confirm their beliefs, is a big threat to cosmology.
The ALICE detector at the Large Hadron Collider may help unravel some of nature’s grestest mysteries.
Our panel of experts speculate on which of science's biggest questions could be answered in the coming months.
Humans have now been living on the International Space Station for 15 years. Here's what we've learned.
Astronomers believe that the dark blue ring in this image must be mysterious dark matter.
While we know that dark matter exists, we have no idea what it is. Luckily, there is no shortage of suggestions.
A cosmological event could have unleased the huge comet or asteroid that led to the demise of the dinosaurs.

The tiniest of particles could have huge potential to solve the greatest mysteries of the universe - including why there is more matter than antimatter.
Dark matter is notoriously hard to detect, but a new experiment might finally shed light on this mysterious substance.
A new detector built deep underground in a gold mine will hopefully unravel the mystery of dark matter.
Understanding how galaxies are arranged could be the key to figuring what causes the expansion of the universe.

A unique map of the galaxies in the sky could shed light on the mysteries of the universe – including dark energy and dark matter.
Running the world's largest particle accelerator requires a lot of energy, but it could reveal the secrets of the universe.
Dark Matter: as simulated, the scaffold that underpins the universe.
Dark matter's mysteries are being steadily unravelled by new studies of remote galaxies.

Scientists know so much about dark matter apart from what it is exactly. But are they getting any closer?
Are you afraid of the dark matter?

Every 30 mil years, Earth has to deal with more comet crashes from space and more intense geological activity from within. Dark matter may be the culprit in these episodes that can cause mass extinction.
Artist’s impression of the Square Kilometre Array at night.
Telescopes have come a long way since the days when they were all about lone astronomers watching the night sky through their upstairs windows. Today teams of astrophysicists build and use much more modern…
This artist’s impression of the Milky Way galaxy. The blue halo of material surrounding the galaxy indicates the expected distribution of the mysterious dark matter.
While invisible, dark matter completely dominates our Milky Way, recent measurements of just how much dark matter there is have revealed a bit of a mystery. In a paper published today in the Astrophysical…
