Big discovery last week. Very big, in the black hole business. Astronomers have detected an extremely massive black hole. Wildly huge. With a mass equivalent to 12 billion of our suns. All the big galaxies, our own, the Milky Way included, have black holes at their core. Ours is only 4 million times the mass of the sun, versus 12 billion in this new discovery. And this giant black hole dates back to the very early era of the universe. And this: this black hole is super-luminous. 40,000 times as bright as our galaxy. This hour On Point: Black hole mania. And we will remember Leonard Nimoy, Mr. Spock.
No mystery is bigger than dark energy - the elusive force that makes up three-quarters of the Universe and is causing it to expand at an accelerating rate. Join a panel of Lawrence Berkeley National Laboratory scientists who use phenomena such as exploding stars and gravitational lenses to explore the dark cosmos.
