What is a famous 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.
Where is the Fermi telescope located?
Fermi, which was called the Gamma-ray Large Area Space Telescope (GLAST) until it reached its operational orbit, launched on June 11, 2008, from Cape Canaveral Air Force Station aboard a Delta II Heavy rocket. It was placed into a circular orbit around Earth with an altitude of about 350 miles (560 kilometers).
Where do Fermi bubbles come from?
The bubbles may be related to the release of vast amounts of energy emitted from the supermassive black hole at the center of our Milky Way galaxy. We know that in other galaxies, supermassive black holes that ingest large amounts of matter can power high-energy jets.
What has the Fermi Gamma-Ray Space Telescope discoveries?
NASA’s Fermi Gamma-ray Space Telescope has identified the farthest gamma-ray blazars, a type of galaxy whose intense emissions are powered by supersized black holes. Light from the most distant object began its journey to us when the universe was 1.4 billion years old, or nearly 10 percent of its present age.
What are the disadvantages of gamma ray telescopes?
Disadvantages of gamma rays compared with X-rays
- Poorer quality radiographs.
- Exposure times can be longer.
- Sources need replacing.
- Radiation cannot be switched off.
- Poorer geometric unsharpness.
- Remote handling necessary.
Where is the Compton telescope located?
Costing $617 million, the CGRO was part of NASA’s “Great Observatories” series, along with the Hubble Space Telescope, the Chandra X-ray Observatory, and the Spitzer Space Telescope….Compton Gamma Ray Observatory.

Is Fermi telescope still working?
Further extension into 2022 In 2019, a NASA Senior Review concluded that Fermi should continue to be operated into 2022, a decision that was subsequently approved by NASA. Further extensions remain possible.
What is the Fermi telescope looking for?
The Fermi Gamma-ray Space Telescope observes the cosmos using the highest-energy form of light, providing an important window into the most extreme phenomena of the universe, from gamma-ray bursts and black-hole jets to pulsars, supernova remnants, and the origin of cosmic rays.
Where did the oldest stars in the Milky Way form?
bulge
The Milky Way’s bulge — a bulbous, 10,000 light-year-wide region of stars and dust popping out of the galaxy’s spiral disc — is thought to contain some of the oldest stars in the galaxy.
How much did the Fermi telescope cost?

Why are gamma ray bursts so hard to study?
Because of their short duration, gamma ray bursts are difficult to “catch.” Astronomers are devising clever techniques in order to learn the cause, frequency and role these events play in the evolution of the universe.
