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]
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⊙.
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 ...
The Advanced CCD Imaging Spectrometer (ACIS), formerly the AXAF CCD Imaging Spectrometer, is an instrument built by a team from the Massachusetts Institute of Technology's Center for Space Research and the Pennsylvania State University for the Chandra X-ray Observatory. ACIS is a focal plane instrument that uses an array of charge-coupled devices.
