Astronomers have discovered a black-hole treasure trove that is changing our view of the cosmos.
Globular clusters are extremely dense stellar systems, in which stars are packed closely together. They are also typically very old—the globular cluster that is the focus of this study, NGC 6397, is almost as old as the Universe itself. It resides 7800 light-years away, making it one of the closest globular clusters to Earth. Because of its very dense nucleus, it is known as a core-collapsed cluster.
The Dallas Mavericks announced a lousy decision this week. At the direction of team owner Mark Cuban, the team will no longer play the National Anthem before its games.
Using NASA's Chandra X-ray observatory, astronomers from the University of Alabama in Huntsville have investigated the central region of the galaxy NGC 1600, focusing on its ultramassive black hole (UMBH). Results of the study, presented in a paper published February 11 on the arXiv pre-print server, shed more light on the properties of this UMBH.
Astronomers might need to adjust their expectations for black holes. According to the New York Times, an international research team has determined that Cygnus X-1, one of the first discovered black holes, is considerably more massive than once thoug
Einstein first predicted the existence of black holes when he published his theory of general relativity in 1916, describing how gravity shapes the fabric of spacetime. But astronomers didn’t spot one until 1964, some 6,070 light-years away in the Cygnus constellation. Geiger counters launched into space detected cosmic x-rays coming from a region called Cygnus
New observations of the first black hole ever detected have led astronomers to question what they know about the Universe's most mysterious objects.
Larger black holes may be the usual attention-getters, but the smaller ones may be at least as important. A team using the Hubble Space Telescope has discovered a concentration of small black holes in the NGC 6397 globular star cluster (pictured abov
It's another home run for coffee consumption — as long as it's black and caffeinated, that is.
