X-Ray Heartbeat May Reveal Smallest Black Hole Ever Found - Yahoo! News:
'via Blog this'
Scientists may have found the smallest black hole yet by listening to its X-ray "heartbeat."
The black hole, if it truly exists, would weigh less than three times the mass of the sun, putting it near the theoretical minimum mass required for a black hole to be stable.
The researchers can't directly observe the black hole, but they measured a rise and fall in X-ray light coming from a binary star system in our Milky Way galaxy that they think signals the presence of a black hole.
Until now, this X-ray pattern, which is similar to a heartbeat registered on an electrocardiogram, has been seen in only one other black hole system. [Images: Black Holes of the Universe]
