Estimate the mass of a black hole on your coffee break -- and thank UMD

Freshly published by the Royal Astronomical Society, UMD's Dr Marc Seigal is putting his discovery into layman's terms.

While you might never need to know the mass of a black hole, it's still good to know that, thanks to Seigal and his research team in Australia, you no longer need spectroscopy and  a lot of expensive telescope time.

In fact, the little schematic shown here and an image of a galaxy is all you need.
