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.
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?
