WASHINGTON, Jan 14 (Reuters) - Scientists have detected emanating from the nucleus of a galaxy relatively close to our Milky Way flashes of X-rays gradually increasing in frequency that seem to be coming from a white dwarf - a highly compact stellar ember - with a death wish.

The observations made using the European Space Agency's XMM-Newton orbiting X-ray telescope appear to show a white dwarf nearing the point of no return - called the event horizon - as it orbits the galaxy's supermassive black hole, according to the researchers.

"It is probably the closest object we've ever observed orbiting around a supermassive black hole. This is extremely close to the black hole's event horizon," said Megan Masterson, a Massachusetts Institute of Technology doctoral student in physics and lead author of the study that was presented at a meeting of the American Astronomical Society in Maryland this week and will be published in the journal Nature.
