New research reveals just how invisible this stuff is, even to itself.
A dwarf galaxy orbiting the Milky Way is humming with gamma rays, leading astronomers to hypothesize that it could be filled with annihilating dark matter particles.
The hunt for the source of dark matter is one of the most hotly anticipated searches of our time and the Higgs boson might be able to light the way to a possible dark matter discovery.
It has long been assumed that the size of a supermassive black hole in a galaxy's core is intimately related to the number of stars that galaxy contains -- but it might not be that simple.
Tonight at 7 p.m., live via Discovery News, we're streaming special public lecture by cosmologist Kendrick Smith, of the Perimeter Institute for Theoretical Physics, in Ontario, Canada.
Giant bubbles of gas that erupted from the core of the Milky Way galaxy millions of years ago are expanding out into space at mind-blowing speeds, according to new observations that may help reveal how the strange balloon-like lobes formed.
We may have found evidence that elusive, mysterious dark matter -- something for which there is no direct proof -- is actually sterile neutrinos. And that's going to take some explaining, by way of a speed-tutorial on quantum mechanics from Julian.
Astronomers may finally have detected a signal of dark matter, the mysterious and elusive stuff thought to make up most of the material universe.
