Unseeable and inescapable, black holes already rank among the more sinister phenomena out in the cosmos. So it may come as disconcerting news that the supermassive black hole at the centre of the Milky Way appears to be growing hungrier.

Astronomers monitoring the colossal object, called Sagittarius A*, found that in the past year it appears to have consumed nearby matter at an unprecedented rate.

“We have never seen anything like this in the 24 years we have studied the supermassive black hole,” said Andrea Ghez, a professor of physics and astronomy at the University of California, Los Angeles, and a senior author of the research. “It’s usually a pretty quiet, wimpy black hole on a diet. We don’t know what is driving this big feast.”
