The Compton Gamma Ray Observatory (CGRO) was a space observatory detecting photons with energies from 20 keV to 30 GeV, in Earth orbit from to The observatory featured four main telescopes in one spacecraft, covering X-rays and gamma rays, including various specialized sub-instruments and ing 14 years of effort, the observatory was Rocket: Space Shuttle Atlantis, STS   Description.

The Compton Gamma-Ray Observatory (GRO) is one of NASA's four "Great Observatories". GRO's specific mission is to study the sources and astrophysical processes (e.g., nuclear reactions, electron bremsstrahlung, matter-antimatter annihilation, elementary particle producation and decay, Compton scattering, and synchrotron radiation).

GRO will make a full-sky survey in the gamma-ray spectral region and characterize many classes of sources. The Schwarzschild-Couder telescope, located at the Fred Lawrence Whipple Observatory in Amado, Arizona, detected gamma-ray showers from the Crab Nebula in earlyproving the viability of the technology design for gamma-ray astrophysics.

Chandra X-Ray Observatory The Chandra X-ray Observatory is the third in NASA’s family of Great Observatories that includes the Hubble Space Telescope and the Compton Gamma Ray Observatory.

Chandra detects X-ray light from very hot (millions of degrees) places in the universe, such as exploding stars, galaxy clusters and matter swirling. A delegation of senior officials from the University of Namibia recently visited the High Energy Stereoscopic System (H.E.S.S.), one of the world’s leading gamma-ray observatories, situated about km south-west Windhoek.

The system is used for detecting gamma rays that carry more than a billion. Gamma-Ray Observatories. SAS 2 and Cos B, launched in the s, made the first surveys of the gamma-ray sky, followed by the Compton Gamma-ray Observatory in and more recently by INTEGRAL in Blazars, pulsars, and many unidentified sources in our galaxy are the gamma-ray emitters.

Fermi (formerly GLAST), the latest gamma-ray. The Compton Gamma Ray Observatory helped open up a new window to the cosmos. And 20 years after its demise, we look back at what it revealed.

By Ben Evans | Published: Thursday, June 4, The Cherenkov Telescope Array, CTA, will be the major global observatory for very high energy gamma-ray astronomy over the next decade and beyond.

The scientific potential of CTA is extremely broad: from understanding the role of relativistic cosmic particles to the search for dark matter. CTA is an explorer of the extreme universe, probing environments from the immediate. The new sky map shows many new gamma ray sources within our own Milky Way galaxy.

Because HAWC observes 24 hours per day and year-round with a wide field-of-view and large area, the observatory boasts a higher energy reach for extended objects.

The Compton Observatory has a diverse scientific agenda, which includes studies of very energetic celestial phenomena: solar flares, gamma-ray bursts, pulsars, nova and supernova explosions, accreting black holes of stellar mass, quasar emission, and interactions of cosmic rays with the interstellar medium.

Question: How Did Observations With The Compton Gamma-ray Observatory Show That Gamma-ray Bursts Were Not Coming From The Milky Way Galaxy. A) The Bursts Were All So “faint” (so Little Energy Reached Us) That They Must Be Very Far Away B) The Gamma-rays Were All Doppler Shifted, Showing The Sources Were Moving Very Fast C) The Gamma-rays.

The Fred Lawrence Whipple Observatory (FLWO) is the largest field installation of the Smithsonian Astrophysical Observatory (SAO) outside Cambridge, MA. The site is on Mt. Hopkins, Arizona.

The major instrument at the site is the MMT Observatory's m diameter optical telescope. Twenty-five years ago this week, NASA launched the Compton Gamma Ray Observatory, an astronomical satellite that transformed our knowledge of the high-energy sky.

Over its nine-year lifetime, Compton produced the first-ever all-sky survey in gamma rays and unveiled a universe that was unexpectedly dynamic and diverse.

The Gamma Ray Observatory (GRO) is a space-based instrument designed to study the universe in an invisible, high-energy form of light known as gamma rays. Although a variety of smaller satellites and high-altitude balloons have carried instruments to study the universe in gamma-ray light during the past 30 years, GRO represents a dramatic.

A short gamma ray burst known to astronomers as SGRBB is the second most-distant well-established SGRB ever seen, and the most distant. However, UHE photon emission may undergo possible ”boosting” due to gamma-ray burst, increasing the expected number of preshower events up to and yielding a minimum required flux of ~ km − 2 yr − 1 to obtain one preshower event, which is about a factor 10 higher than upper limits put by the Pierre Auger Observatory and.

Judy studies Gamma-ray Bursts (GRBs) with both the Fermi Gamma-ray Burst Monitor (GBM) and the Large Area Telescope (LAT), as well as the Neil Gehrels Swift Observatory. She is especially interested in the extremely energetic GRBs detected in the high-energy gamma-ray band with the LAT, and also what can be learned by probing short GRBs with.

Gamma-ray detections can also be made from Earth’s surface by using the atmosphere as the primary detector. When a gamma ray hits our atmosphere, it accelerates charged particles (mostly electrons) in the atmosphere.

Those energetic particles hit other particles in the atmosphere and give off their own radiation. Altitude of the observatory. By increasing the altitude of the observatory location one can approach the point at which the number of particles in the gamma-ray induced shower is maximum, and this gives the possibility to decrease the energy threshold of the gamma-ray.

Overview. The HAWC Gamma-ray Observatory is a wide field of view, continuously operating, TeV gamma-ray telescope that explores the origin of cosmic rays, study the acceleration of particles in extreme physical environments, and search for new TeV was built at an elevation of m above sea level in Mexico by a collaboration of 15 US and 12 Mexican.

Gamma-rays coming from space are mostly absorbed by the Earth's gamma-ray astronomy could not develop until it was possible to get our detectors above all or most of the atmosphere, using balloons or spacecraft.

The first gamma-ray telescope carried into orbit, on the Explorer XI satellite inpicked up fewer than cosmic gamma-ray. compton gamma ray observatory When it was launched inthe Compton Gamma Ray Observatory was the biggest space observatory ever. It mapped hundreds of gamma ray sources and recorded more than 2, gamma ray bursts, signs of the most violent happenings in the Universe.

On August 1,the High-Altitude Water Cherenkov (HAWC) Gamma Ray Observatory formally began operations. HAWC is designed to study the origin very high-energy cosmic rays and observe the most energetic objects in the known universe.

Hence, the optical afterglow of these strong bursts of gamma-ray radiation should be rapidly monitored. Within a few hours after the Neil Gehrels Swift Observatory of NASA identified the object and announced a global alert, Paterson’s research team immediately pointed the Keck I and Gemini North telescopes toward the site of the SGRB.

Ten billion years ago, two massive bodies, presumably neutron stars, spiralled into each other, merging in a cataclysmic blast that produced a short gamma ray burst, or SGRB. Such events generate enormous amounts of energy, in the blink of.

This view from NASA's Fermi Gamma-ray Space Telescope is the deepest and best-resolved portrait of the gamma-ray sky to date. The image shows how the sky appears at energies more than million.

Gamma-ray astronomy is already at the heart of the new multi-messenger astrophysics, and the SCT technology will make it an even more important player,” Vandenbroucke said. The use of secondary mirrors in gamma-ray telescopes is a leap forward in innovation for the relatively young field of very-high-energy gamma-ray astronomy, which has.

The $ million observatory they sent into orbit June 11 has awoken to begin its observation of the gamma-ray light from celestial mystery object such as. Gamma Ray Craft Exiting in Blaze of Glory By JOHN NOBLE WILFORD (Ma ) The Compton Gamma Ray Observatory's days are numbered, but even to the last, the spacecraft is challenging scientists with valedictory surprises that make them regret the imminent loss all the more.

Last week they were scratching their heads over the discovery of. Gamma-ray astronomy, study of astronomical objects and phenomena that emit gamma rays. Gamma-ray telescopes are designed to observe high-energy astrophysical systems, including stellar coronas, white dwarf stars, neutron stars, black holes, supernova remnants, clusters of galaxies, and diffuse gamma-ray background radiation found along the plane of the Milky Way.

SGRBB is the most distant short gamma ray burst with its afterglow measured Incredibly fast and faint, these events are notoriously difficult to catch Event offers a rare opportunity to. Today, scientists operating the High Altitude Water Cherenkov (HAWC) Gamma-ray Observatory released a new survey of the sky made from the highest energy gamma rays ever observed.

The new sky map. Compton Gamma Ray Observatory, and the Chandra X-ray Observatory to find the answers to numerous questions about the universe.

With the capabilities the Space Shuttle provides, scientist now have the means for deploying these observatories from the .The Compton Gamma-Ray Observatory (CGRO) was launched on April 5, The second of NASA’s great observatories, CGRO has four instruments that cover an unprecedented six orders of magnitude in energy, from 30 keV to 30 GeV.The premier gamma-ray observatory far exceeded expectations for a two- to five-year mission, but a recent gyroscope failure has prompted NASA to decide to steer the satellite safely back into the atmosphere.

Compton's lasting legacy of discovery will include the detection of more than celestial gamma-ray sources.
