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 […]

NASA Space Telescope Sees Possible X-Ray 'Screams' From Zombie Stars

It sounds like something from a bad sci-fi movie, but a NASA space telescope has detected what might be the X-ray “screams” from dead (zombie) stars. The […]

Stellar (and Planetary) Formation Near Milky Way's Supermassive Black Hole Possible, New Study Suggests

An artist’s illustration of the vicinity of the supermassive black hole in the center of the Milky Way galaxy, known as Sagittarius A* . Astronomers have discovered a population of more than 150 massive young stars (shown as blue dots) in recent years that orbit within 2 light-years from the black hole. Newer […]

Astronomers Detect Complex Organics Around Nearby Young Star; Produce Them in Simulated Conditions in the Lab

Artist’s impression of the protoplanetary disk surrounding the young star MWC 480. Astronomers using the Atacama Large Millimeter/submillimeter Array, or ALMA, have detected the complex organic molecule methyl cyanide in the outer reaches of the star’s protoplanetary disk, where comets are believed to form. This discovery suggests that complex organic chemistry and potentially […]

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 […]

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.
