Hubble and Chandra Unveil Mysteries Concerning Dark Matter

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 […]

Chandra X-Ray Observatory Continues to Unfold Secrets of Universe

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 […]

Rough Cosmic Waters: Chandra X-ray Observatory Reveals 'Turbulent' Effect of Black Holes

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 […]

Chandra X-Ray Observatory Reveals 'Black Hole Bonanza' in Andromeda Galaxy

Data from Chandra’s X-ray Observatory has led astronomers to unveil 26 black holes in the Milky Way’s neighbor, the Andromeda Galaxy. 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.
