Hard Science

NASA has detected supermassive black holes in galaxies that formed 12 billion years ago.

These Supermassive Black Holes Have Completely Stumped Scientists

We can get a glimpse back in time by looking out into space.

The quest to identify what dark matter is remains mostly fruitless. But through the Fermi Large Area Telescope (LAT), scientists were able to cross off one more contender from the list: Axion-like particles (ALPs).

Dark Matter is Not Axion-like Particles

The long list of what dark matter is NOT just got longer.

A faint signal was detected less than half a second after picking up the gravitational wave signal, and in the same region of space.

NASA May Have Detected Light From the Gravitational Wave Black Hole Merger

Black holes are messy eaters—there may be exceptions to what they can swallow, and what they can't might just give them away.

The Fermi Gamma-ray Space Telescope detected a weak flash of X-rays less than half a second after the gravitational wave event detected by LIGO; the source of the flash was in the same part of the sky as the ancient black hole merger, and allows researchers to further narrow down its source.

NASA Telescope May Have Spotted The Gravitational Wave Source

We are narrowing in on the source.

New analysis by U.S. and European teams indicates that the excess of gamma rays emanating from the center of the galaxy probably comes from pulsars, not dark matter.  Future radio surveys should find these objects, which must number in the hundreds if not thousands.
