Astronomers have discovered a flattened structure of matter around the Milky Way that explains the unusual motion of nearby ...

The oldest stars in the Milky Way are forcing a fresh look at one of cosmology’s biggest arguments. If some of them are about ...

Forces have mediator particles. Electromagnetism is mediated by the photons, for example. So most of the decay of this excited dark matter particle would be this unknown mediator. The excited state ...

For decades, astronomers wondered why most nearby galaxies are speeding away from the Milky Way instead of being pulled in by ...

For billions of years before reaching its current location, the Sun may have slowly travelled as part of a large group, or ...

Astronomers from the University of Groningen have discovered that the Milky Way does not move in the cosmic void, but is embedded in a flat "sheet" of dark matter. This was reported on March 11 in the ...

Using data from the Magellan Clay telescope and the Canada-France-Hawaii Telescope (CFHT), astronomers have investigated a ...

Scientists at King's College London propose that mysterious signals from the Milky Way's centre are linked to excited dark ...

Like tiny photobombers, cosmic anomalies resembling small, bright red points show up in almost every snapshot taken by the ...

Deep inside the Milky Way, an invisible force is quietly holding everything together — its magnetic field. Now, researchers have created one of the most detailed maps ever of this hidden structure, ...

The Andromeda Galaxy, the nearest major galaxy to the Milky Way, is slowly moving toward us at incredible speed. Astronomers ...

A team of astronomers led by researchers at the University of Groningen has identified a colossal sheet of dark matter and ...
