Gamma-ray astronomy has become a rich field of research and matured significantly since the launch of NASA's Compton Gamma Ray Observatory in April 1991. Studies of the diffuse gamma-ray emission of the Galaxy can now be performed in far more detail and extended into the MeV regime, ...
Because Earth's atmosphere blocks most gamma-rays, they're seen only with high-altitude balloons and orbiting telescopes. Further reading: NASA resource on the electromagnetic spectrum. Watch: What Are Gamma Rays? by NASA. Gamma Rays & Cosmic Sources, from the Cherenkov Telescope Array. This ...

Gamma Ray Make-up:Gamma rays are highly energetic rays and are part of the electromagnetic (EM) spectrum at the far end of high frequencies and corresponding short wavelengths even higher than x-rays.Answer and Explanation: Gamma rays like all types of EM radiation are made up of photons (...
Readers including Patrick Falini of Baltimore, Md., pointed out a new research paper finding evidence that Earth was hit by a storm of gamma raysabout 1,200 years ago,perhaps set off by the collision of two black holes, or of two very old neutron stars. The gamma-ray storm of 1,200...
How does your work involve gamma-ray bursts? When a GRB happens, it produces a jet of gamma-rays and other material. When this material interacts with all the other dust and particles around it, it energizes that material, which then produces emission from the X-ray to radio bands, known...
in Tokyo; fledgling rays of sunlight peek over her pixelated shoulders. Qvist explains why Japan represents such a big opportunity for Spotify. “Japan has been a very physical market,” she says. “We have the ability and opportunity to show them things they haven’t seen before.” The ...
(or at least, it stops emitting enough radiation for telescopes to detect), Harding said. Observations thus far suggest that pulsars drop below the detection threshold with gamma rays before radio waves. When pulsars reach this stage of life, they enter what's known as the pulsar graveyard. ...
Matter—the visible kind, that is—interacts with the universe in many ways. It absorbs and, in many cases, emits electromagnetic radiation in the form of gamma rays, visible light, infrared, and more. It can generate magnetic fields of various sorts and strengths. Matter has mass, creating...
