The Chandra X-ray Observatory (CXO), previously known as the Advanced X-ray Astrophysics Facility (AXAF), is a Flagship-class space telescope launched aboard the Space Shuttle Columbia during STS-93 by NASA on July 23, 1999.
Chandra's large size, high orbit, and sensitive CCDs allowed observations of very faint X-ray sources. Spitzer also observes at wavelength largely inaccessible to ground telescopes. It was preceded in space by NASA's smaller IRAS mission and European Space Agency (ESA)'s large ISO telescope. Spitzer's instruments took advantage of the rapid ...
A combination of many unresolved X-ray sources is thought to produce the observed X-ray background. Photo ... Chandra X-ray Observatory: NASA: 23 Jul 1999 ...
The primary objective of the STS-93 mission was to deploy the Chandra X-ray Observatory (formerly the Advanced X-ray Astrophysics Facility) with its Inertial Upper Stage booster. At its launch, Chandra was the most sophisticated X-ray observatory ever built. It is designed to observe X-rays from high energy regions of the universe, such as hot ...
The elliptical galaxy LEDA 1900245, is the brightest cluster galaxy (BCG) of RX J1532.9+3021. It has a dimension of around 120.56 kpc (~393,000 light-years) and is a LINER galaxy, meaning a galaxy whose nucleus contains an emission spectrum characterized by broad lines of weak ion atoms. [8]
That group would later go on to launch the Einstein Observatory (the first imaging X-ray telescope) in 1976, and ultimately lead the proposals and development of what would become the Chandra X-ray Observatory. Chandra, the second of NASA's Great Observatories and still the most powerful X-ray telescope in history, continues operations today as ...
Chandra X-ray Observatory, launched by NASA in 1999, is still operational as of 2024 An X-ray telescope ( XRT ) is a telescope that is designed to observe remote objects in the X-ray spectrum. X-rays are absorbed by the Earth's atmosphere , so instruments to detect X-rays must be taken to high altitude by balloons , sounding rockets , and ...
