ESOcast 39: A Black Hole's Dinner is Fast Approaching
The astronomy podcast exploring the cosmic frontier with Dr J
14 декабря 2011 г.
This episode of the ESOcast looks at exciting new observations of a mysterious object that is a favoured theme in science fiction: the black hole. But the science fiction is fast becoming science fact, and the ending won’t be a happy one for the black hole’s victim.
Astronomers using ESO’s Very Large Telescope have discovered a gas cloud with several times the mass of the Earth accelerating fast towards the black hole at the centre of the Milky Way. This is the first time ever that the approach of such a doomed cloud to a supermassive black hole has been observed.
Watch the episode to learn more about how astronomers discovered this cloud, and what is going to happen to it over the next few years.
