What is Gamma telescope?
Gamma-ray telescope, instrument designed to detect and resolve gamma rays from sources outside Earth’s atmosphere. Gamma rays are the shortest waves (about 0.1 angstrom or less) and therefore have the highest energy in the electromagnetic spectrum.
What is an example of a gamma ray telescope?
The Fermi telescope has two main instruments. It has a large telescope that finds gamma rays with 10 million to more than 300 billion times the energy of visible light. The spacecraft also has detectors that observe gamma-ray bursts. Gamma-ray bursts are brief flashes of gamma rays.
Do we have gamma-ray telescopes?
The Fermi Gamma-Ray Telescope is a space observatory designed to study the universe in highly energetic frequencies known as gamma-rays. It includes participation from NASA, the U.S. Department of Energy, and several partners both in the United States and internationally.
Who owns the Fermi Gamma Ray Space Telescope?
NASA
Fermi was launched on 11 June 2008 at 16:05 UTC aboard a Delta II 7920-H rocket. The mission is a joint venture of NASA, the United States Department of Energy, and government agencies in France, Germany, Italy, Japan, and Sweden, becoming the most sensitive gamma-ray telescope on orbit, succeeding INTEGRAL.
How is a gamma-ray made?
They are produced by the hottest and most energetic objects in the universe, such as neutron stars and pulsars, supernova explosions, and regions around black holes. On Earth, gamma waves are generated by nuclear explosions, lightning, and the less dramatic activity of radioactive decay.
What uses gamma?
Uses of Gamma Rays:
- Sterilize medical equipment.
- Sterilize food (irradiated food)
- Used as tracers in medicine.
- Radio Therapy- In oncology, to kill cancerous cells.
- Gamma-Ray Astronomy.
Who studies gamma rays?
astronomers
These are produced by spectacular events in the Universe such as stars exploding, matter falling into black holes and celestial objects colliding. By collecting gamma rays, astronomers are able to see these violent events and can judge exactly how they shape the Universe.
Who discovered gamma rays?
Paul Villard
Gamma radiation is one of the three types of natural radioactivity discovered by Becquerel in 1896. Gamma rays were first observed in 1900 by the French chemist Paul Villard when he was investigating radiation from radium [1]. They are emitted by a nucleus in an excited state.
Who invented Fermi telescope?

When did Fermi telescope end?
2018
After five years of operations, on Aug. 11, 2013, Fermi entered an extended phase of its mission, a deeper study of the high-energy cosmos. This is a significant step toward the science team’s planned goal of a decade of observations, ending in 2018.
Who discovered gamma?
How does a gamma-ray telescope work?
Since gamma rays have so much energy, they pass right through the mirror of a standard optical telescope. Instead, gamma rays are detected by the optical flashes they produce when interacting with the material in a specially designed instrument such as a scintillation detector.
What are facts about gamma rays?
Facts about gamma radiation: 1. Production of Gamma Radiation. Gamma rays are produced from the excited nucleus of a radioactive element. An excited radioactive element decays to form its daughter element by a process called isometric transition.
What uses do gamma rays have?
Though gamma rays are bio-hazardous in nature, they can be controlled and used for various important purposes: It is used in the treatment of cancer without surgery. It is used to sterilize surgical instruments. It is also used in the food industry to kill harmful bacteria.
What does the Fermi Gamma-ray Space Telescope do?
The Fermi Gamma-ray Space Telescope (FGST), formerly called the Gamma-ray Large Area Space Telescope (GLAST), is a space observatory being used to perform gamma-ray astronomy observations from low Earth orbit.
