Previously known as the Advanced X-ray Astrophysics Facility […] 
Eileen Collins was the first woman to make the cut as a Space Shuttle pilot and eventually the first female to command a crew of astronauts into orbit. Photo Credit: NASA Twenty years ago, this week, First Lady Hillary Clinton—flanked by President Bill Clinton to her left and NASA Administrator Dan Goldin to […] From HubbleSite: “This collage shows images of six different galaxy clusters taken with NASA’s Hubble Space Telescope and Chandra X-ray Observatory. The clusters were observed in a study of how dark matter in clusters of galaxies behaves when the clusters collide. Seventy-two large cluster collisions were studied in total. Using visible-light images from […] From NASA: “A newly discovered object in the galaxy NGC 2276 may prove to be an important black hole that helps fill in the evolutionary story of these exotic objects. This source , known as NGC2276-3c, is likely an intermediate-mass black hole with about 50,000 times the mass of the Sun. The main […] From NASA: “Chandra observations of the Perseus and Virgo galaxy clusters suggest turbulence may be preventing hot gas there from cooling, addressing a long-standing question of galaxy clusters do not form large numbers of stars.” Image Credit: NASA/CXC/Stanford/I. Zhuravleva et al This week, NASA announced that the Chandra X-ray Observatory, now in its […] Columbia roars into the darkened Florida sky at 12:31 a.m. EDT on 23 July 1999. It would be one of the most hazardous launch phases in shuttle history. Photo Credit: NASA Fifteen years ago, this week, the first woman ever to lead a space mission was launched aboard Shuttle Columbia to deliver NASA’s […] Eileen Collins, the first female spacecraft commander in history, floats in Columbia’s middeck, 15 years ago this week. Photo Credit: NASA “It’s great to be back in zero-g again,” said STS-93 commander Eileen Collins, early on 23 July 1999, as she and her four crewmates set about preparing the Shuttle Columbia for five […] The STS-93 crew poses with a model of the Chandra X-Ray Observatory. This shuttle mission also entered into the history books for having the first female commander (Eileen Collins, here joined by Steven Hawley, Jerry Ashby, Michel Tognini, and Cady Coleman).

This is the largest number of black hole candidates found in a galaxy outside our own. Image Credit: X-ray: NASA/CXC/SAO/R. Barnard, Z. Lee et al.; Optical: NOAO/AURA/NSF/REU Program/B. Schoening, V.
