What is an example of an X-ray telescope?
The most important X-ray astronomy mission of the present decade is NASA’s Chandra X-ray Observatory, which was launched on July 23, 1999. This telescope contains four sets of nested mirrors and is the premier X-ray observatory to date. The mirror surface was coated with iridium, a material more reflective than gold.
What is a famous X-ray telescope?
The Chandra X-ray Observatory is the world’s most powerful X-ray telescope. It has eight-times greater resolution and is able to detect sources more than 20-times fainter than any previous X-ray telescope. Credits: NASA/CXC & J.Vaughan.
Where are X-ray telescopes found?
The Smithsonian’s Astrophysical Observatory in Cambridge, MA, hosts the Chandra X-ray Center which operates the satellite, processes the data, and distributes it to scientists around the world for analysis. The Center maintains an extensive public web site about the science results and an education program.
What do X-ray telescopes view?
Similar to the way an optical telescope increases our eye’s ability to see faint stars, an X-ray telescope can concentrate the light from an X-ray star onto an electronic eye. An imaging detector can view several X-ray emitting objects simultaneously, or can create pictures of regions of diffuse X-ray emission.
What are ultraviolet telescopes used for?
ultraviolet telescope, telescope used to examine the ultraviolet portion of the electromagnetic spectrum, between the portion seen as visible light and the portion occupied by X-rays.
What are gamma ray telescopes used for?
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 type of telescope is Spitzer?
infrared space telescope
At its launch in 2003, NASA’s Spitzer Space Telescope was the most sensitive infrared space telescope in history. Its 16-year lifetime revolutionized our view of the cosmos. Spitzer made discoveries from inside our solar system to nearly the edge of the Universe.
What are some examples of ultraviolet telescopes and where are they located?
Other important ultraviolet space observatories include the Galaxy Evolution Explorer (GALEX), which was launched in 2003 and observes between 140 and 280 nm. GALEX is designed to observe hot young stars in other galaxies. The Hubble Space Telescope (HST) can also serve as an ultraviolet telescope.
What type of telescope is Compton?
gamma-ray detector
A Compton telescope (also known as Compton camera or Compton imager) is a gamma-ray detector which utilizes Compton scattering to determine the origin of the observed gamma rays.
What do Spitzer telescopes see?
The Spitzer Space Telescope, launched in 2003, was NASA’s Infrared Great Observatory. Among many other accomplishments in its 16 years of operation, Spitzer discovered a giant ring of Saturn, revealed a system of seven Earth-size planets around a star 40 light-years away, and studied the most distant known galaxies.
How does the X ray telescope work?
An optical telescope uses a large, curved-glass primary mirror to gather light, but X-rays would penetrate such a mirror’s reflective coating; an X-ray telescope’s mirrors must be facing almost perpendicular to the path of incoming light so that the photons graze the surface like stones skipping across a pond.
What is an X – ray telescope?
An X-ray telescope (XRT) is a telescope that is designed to observe remote objects in the X-ray spectrum. In order to get above the Earth’s atmosphere, which is opaque to X-rays, X-ray telescopes must be mounted on high altitude rockets, balloons or artificial satellites.
What is X – ray in astronomy?
X-ray astronomy is an observational branch of astronomy which deals with the study of X-ray observation and detection from astronomical objects.
