Latest Stellar black hole Stories
NASA’s Chandra X-ray Observatory caught signs of what appeared to be a black hole eating gas at the middle of the nearby Sculptor galaxy nearly a decade ago. A new observation by NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) has found the black hole asleep.
In today's Your Universe Today Podcast, we talked with theoretical physicist Dr. Kelly Holley-Bockelmann about mysterious supermassive black holes, which are millions or billions times larger than our Sun.
A new stellar-mass black hole has been discovered in our galaxy by NASA's Swift satellite. High-energy X-rays emanating from a source towards the center of our Milky Way galaxy were observed, indicating the presence of a previously unknown black hole.
A surprising black hole discovery made while using the National Science Foundation's Karl G. Jansky Very Large Array (VLA) is causing scientists to change what they know of globular star clusters.
Astronomers have identified an X-ray signal that followed an observation made last year of a quiescent black hole in a distant galaxy. The black hole discovered by the team last year was seen erupting after shredding and consuming a passing star.
Researchers from several American institutes and agencies have developed a new model showing how an elusive type of black hole can be formed in the gas surrounding their supermassive counterparts.
Observations with CSIRO's Australia Telescope Compact Array have confirmed that astronomers have found the first known "middleweight" black hole.
Astronomers have spotted the first known "middleweight" black hole, according to a publication in Science Express.
Astronomers have for the very first time captured a supermassive black hole devouring a wandering star that strayed too close to a phenomena that nothing can escape, not even light.
Astronomers using NASA's Chandra X-ray Observatory have found evidence for a population of old stellar black holes. The discovery provides new insight into the nature of stellar black holes, which is a class that can produce as much energy in X-rays as what a million suns could radiate at all wavelengths.
Cygnus X-1 -- Cygnus X-1 (often abbreviated to Cyg X-1) is an X-ray source in the Cygnus constellation considered to be one of the most likely black hole candidates. The optical counterpart (HDE 226868) is a variable 8.9 magnitude star (visible with good binoculars in good observing conditions.) at right ascension 19 h 56.5 min and declination of 35 deg 4 min (for 1950 epoch). Cyg X-1 is a binary star that contains a O9-B0 supergiant (with a surface temperature of 31000 Kelvin) and a...
