Dark matter detector observes rarest event ever recorded

How do you observe a process that takes more than one trillion times longer than the age of the universe? The XENON Collaboration research team did it with an instrument built to find the most elusive particle in the universe—dark ...

Hubble detects smallest known dark matter clumps

When searching for dark matter, astronomers must go on a sort of "ghost hunt." That's because dark matter is an invisible substance that cannot be seen directly. Yet it makes up the bulk of the universe's mass and forms the ...

In theory, the Milky Way could be a 'galactic transport system'

Based on the latest evidence and theories our galaxy could be a huge wormhole (or space-time tunnel, have you seen "Interstellar?") and, if that were true, it would be "stable and navigable". This is the hypothesis put forward ...

Astronomers witness galaxy megamerger

Peering deep into space—an astounding 90 percent of the way across the observable universe—astronomers have witnessed the beginnings of a gargantuan cosmic pileup, the impending collision of 14 young, starbursting galaxies.

Simple theory may explain dark matter

Most of the matter in the universe may be made out of particles that possess an unusual, donut-shaped electromagnetic field called an anapole.

New results from world's most sensitive dark matter detector

The Large Underground Xenon (LUX) dark matter experiment, which operates nearly a mile underground at the Sanford Underground Research Facility (SURF) in the Black Hills of South Dakota, has already proven itself to be the ...
