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. ESA, HFI & LFI consortia (2010)

From dark gravity to phantom energy: what’s driving the expansion of the universe?

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.

How we plan to bring dark matter to light

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. ESA/Hubble, NASA and S. Smartt (Queen's University Belfast)

Galaxy survey to probe why the universe is accelerating

A unique map of the galaxies in the sky could shed light on the mysteries of the universe – including dark energy and dark matter.

Shedding new light on the search for the ‘invisible’ dark matter

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

Dark matter and the Milky Way: more little than large

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…

From black holes to dark matter, an astrophysicist explains

Katherine Mack, astrophysicist at the University of Melbourne, answered questions posed by the public on Reddit. The Conversation has curated the highlights. Dark Matter How do you explain dark matter…

Filaments that bind galaxies together illuminated by a quasar

According to cosmologists, galaxies are joined together by filaments, quite literally. These filaments form the cosmic web and are made of mostly dark matter, many stars and some gas. Observing these filaments…

Dark matter experiment finds nothing, makes news

A US team with a highly sensitive dark matter detector has just finished its first run. It has found nothing, and that is still big news. Physicists can explain accurately the behaviour of what makes matter…
