The gigantic black hole at the heart of our Milky Way galaxy may be devouring asteroids on a daily basis, a new study suggests. For several years, NASA's Chandra spacecraft has detected X-ray flares about once a day coming from our galaxy's central black hole, which is known as Sagittarius A* (Sgr A* for short). These flares may be caused by asteroids falling into the super massive black hole's maw, according to the study.
"People have had doubts about whether asteroids could form at all in the harsh environment near a super massive black hole," study lead author Kastytis Zubovas, of the University of Leicester in the United Kingdom, said in a statement. "It's exciting because our study suggests that a huge number of them are needed to produce these flares. "Though scientists have suspected for a while that a giant black hole lurks at the center of our galaxy, they still can't say for sure it's the explanation for the strange behavior observed there. Now researchers are closer than ever to being able to image this region and probe the physics at work – potentially shedding light on the great conflict between the theories of general relativity and quantum mechanics. From Art View as new satellites powered by neutron signal's these satellites will bring grater understanding to our future colonisation of other planets no need for large engines it just simple MHz rotation power out through the bellies many thousands of satellites at a fraction of the cost maybe become our human salvation. At the heart of the Milky Way, astronomers see some wacky things. For example, about a dozen stars seem to be orbiting some invisible object. One star has been found to make a 16-year orbit around the unseen thing, moving at the hard-to-imagine speed of about 3,000 miles (5,000 kilometers) a second. By comparison, the sun moves through space at a comparatively glacial 137 miles (220 kilometers) a second.
