Astronomers discover star racing around black hole at Milky Way center
UCLA astronomers report the discovery of a remarkable star that orbits the enormous black hole at the center of our Milky Way galaxy in a blistering 11-and-a-half years—the shortest known orbit of any star ...
For the first time, astronomers have measured the radius of a black hole
(Phys.org)—The point of no return: In astronomy, it's known as a black hole—a region in space where the pull of gravity is so strong that nothing, not even light, can escape. Black holes that can be billions ...

India: Enough about Higgs, let's discuss the boson
(AP) While much of the world was celebrating the international cooperation that led to last week's breakthrough in identifying the existence of the Higgs boson particle, many in India were smarting over what they saw as a slight ...
A roll of the dice: Quantum mechanics researchers show that nature is unpredictable
Many of the predictions we make in everyday life are vague, and we often get them wrong because we have incomplete information, such as when we predict the weather.
