The Chandra X-ray Observatory marked its 25th anniversary with a release of never-before-seen images. But budget cuts may cause the observatory’s days to be numbered.
Chandra is sensitive to X-ray sources 100 times fainter than any previous X-ray telescope, enabled by the high angular resolution of its mirrors. Since the Earth's atmosphere absorbs the vast majority of X-rays , they are not detectable from Earth-based telescopes ; therefore space-based telescopes are required to make these observations.
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]
The Chandra x-ray mirrors resulted from over two decades of collaboration between Van Speybroeck and colleagues at the Smithsonian Astrophysical Observatory and scientists and engineers affiliated with NASA's Marshall Space Flight Center, TRW Inc., Hughes-Danbury (now BF Goodrich Aerospace), Optical Coating Laboratories, Inc. and Eastman-Kodak.

PKS 0637-752 contains an active galactic nucleus.It is classified a blazar, a type of an active galaxy with a relativistic jet pointing towards Earth's direction. [6] [7] Like other quasars, PKS 0637-752 is considered luminous, powering up 10 trillion times the sun, with a supermassive black hole in its center.
The Chandra X-ray source detected in UHZ1 is Compton-thick. [a] It has a bolometric luminosity of L bol ~ 5 × 10 45 erg s × 10 −1, corresponding to an estimated BH mass of ~ 4 × 10 7 M⊙.
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 ...
