Unusual galaxies defy dark matter theory

After drawing both praise and skepticism, the team of astronomers who discovered NGC 1052-DF2 – the very first known galaxy to contain little to no dark matter – are back with stronger evidence about its bizarre nature.

Hubble and Gaia accurately weigh the Milky Way

In a striking example of multi-mission astronomy, measurements from the NASA/ESA Hubble Space Telescope and the ESA Gaia mission have been combined to improve the estimate of the mass of our home galaxy the Milky Way: 1.5 ...

ATLAS releases first result using full LHC Run 2 dataset

The Large Hadron Collider (LHC) is currently shut down for a major two-year upgrade programme. However, LHC researchers are busy analysing the large dataset they have collected during the machine's second run (Run 2), which ...

Finding dark matter in the dark

Dark matter is the mysterious material that holds the Universe together, yet no one has seen it; or heard, smelled, tasted or touched it either.

CERN lab on the hunt for dark matter

Europe's physics lab CERN on Tuesday said it was planning a new experiment to look for particles associated with dark matter which is believed to make up some 27 percent of the universe.

Dark matter may be hitting the right note in small galaxies

Dark matter particles may scatter against each other only when they hit the right energy, say researchers in Japan, Germany, and Austria in a new study. Their idea helps explain why galaxies from the smallest to the biggest ...

Where is the universe hiding its missing mass?

Astronomers have spent decades looking for something that sounds like it would be hard to miss: about a third of the "normal" matter in the Universe. New results from NASA's Chandra X-ray Observatory may have helped them ...

Mapping historical changes in dark matter

Combining Einstein's theory of relativity with one of the most powerful telescopes in the world has helped an international team of researchers measure where and how dark matter structures grow in the universe. Their analysis ...
