A small but distinctive signal in X-rays from the Milky Way could be key to proving the existence of dark matter.
Astronomers in the US are setting up an experiment which, if it fails – as others have – could mark the end of a 30-year-old theory
The universe is suspected to be loosing its mass ever since the big bang.
New research may cause scientists to rethink everything we think we know about dark matter.
One of the great mysteries of the cosmos is why it is expanding at an apparently accelerating rate.
THE end of the universe is about to get interesting. Most data favours a slow fade into a silent, frozen oblivion. But a new analysis suggests the cosmos could gradually tear itself apart, galaxy from galaxy and atom from atom. Or at least, we can’t rule it out.
The discovery of two massive holes punched through a stream of stars could help answer questions about the nature of dark matter, the mysterious substance holding galaxies together.
Scientists have discover a nearby galaxy that’s roughly the same mass as the Milky Way, but somehow contains fewer than 1 percent of its stars.
