Increased X-Ray Activity From Milky Way's Supermassive Black Hole Puzzles Astronomers

An X-ray view (at the bottom) of the region around Sgr A*, the supermassive black hole at the center of the Milky Way galaxy, taken with NASA’s Chandra X-ray Observatory. The analysis of archival observations from Chandra and other orbiting X-ray telescopes has revealed that Sgr A* has increased its X-ray flaring by […]

Astronomers Measure Galactic Winds at Milky Way's Center, Detect Record-Breaking X-Ray Flares From Its Supermassive Black Hole

A composite image of the area around the supermassive black hole at the center of the Milky Way, known as Sagittarius A* (Sgr A*), taken with NASA’s Chandra X-ray space telescope. The colors in the main image represent medium, and high-energy X-rays as red, green, and blue respectively. The inset box shows a […]

Chandra X-Ray Observatory Helps Astronomers Weigh Most Massive Galaxy Cluster Discovered to Date

A composite, multi-wavelength image of the young galaxy cluster XDCP J0044.0-2033, also known as the Gioiello Cluster, which is located 9.6 billion light-years away. In the image, X-ray wavelengths appear purple, infrared appear as large red halos around some galaxies, and visible light appears as are red, green, and blue. Image Credit: X-ray: […]

New Research Suggests Potential Link Between Neutrinos and the Supermassive Black Hole at Milky Way's Center

An unprecedented view of the black hole at the center of the Milky Way Galaxy, known as Sagittarius A*, that was obtained with NASA’s Chandra X-ray Observatory. A new study has provided evidence that Sagittarius A* is a source of high-energy neutrinos. Image Credit: NASA/CXC/Univ. of Wisconsin/Y.Bai. et al.

NASA's NuSTAR Telescope Discovers 'Impossible' Ultra-Luminous Pulsar

NASA’s NuSTAR telescope recently discovered an ultra-luminous X-ray source (shown in the pink area in the circle) inside the nearby galaxy M82. This newly-discovered X-ray source was found to be powered by an extremely luminous pulsar, which produces the energy equivalent of 10 million Suns. Image Credit: NASA/JPL-Caltech

Our ever-more-detailed study of the […]

NuSTAR Sheds New Light on Supernova Explosions

This is the first map of radioactivity in a supernova remnant, the blown-out bits and pieces of a massive star that exploded. The blue color shows radioactive material mapped in high-energy X-rays using NuSTAR. Heated, non-radioactive elements previously imaged by Chandra using low-energy X-rays are shown in red, yellow, and green. Image Credit/Caption: […]

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. Harvey and […]
