Cosmic sink-holes or Black Holes is a region of spacetime from which nothing, not even light, can escape. The theory of general relativity predicts that a sufficiently compact mass will deform spacetime to form a black hole. Around a black hole there is a mathematically defined surface called an event horizon that marks the point of no return. It is called “black” because it absorbs all the light that hits the horizon, reflecting nothing, just like a perfect black body in thermodynamics. Quantum mechanics predicts that black holes emit radiation like a black body with a finite temperature. This temperature is inversely proportional to the mass of the black hole, making it difficult to observe this radiation for black holes of stellar mass or greater.

Newly-discovered exoplanet orbits around two stars
For the first time, astronomers have captured a planet that orbits around two stars instead of one.
“If you could visit there, you would see a sky with two suns, just like Luke Skywalker,” said Nick Gautier, an astronomer at NASA’s Jet Propulsion Laboratory in Pasadena, California. He was speaking at a NASA press conference to announce the discovery. The finding will appear in the Sept. 16 issue of Science. […]
Using the Kepler space telescope, astronomers spotted the Saturn-sized planet traveling around a pair of stars approximately 200 light-years away. The exoplanet takes about 229 days to orbit its dual parent stars.](http://24.media.tumblr.com/tumblr_lrodeioDml1qgfmcuo1_1280.jpg)

Inner workings of black holes finally revealed
The innermost parts of a black hole’s active jets have been revealed for the first time. The observation suggests that the energetic spouts are more dynamic than previously suspected, with enormous blasts firing off randomly over timescales as short as 11 seconds.
It is somewhat odd that black holes, which are ultra-dense balls of matter from which no light can escape, can produce energetic flares. But these jets are a byproduct of gas and dust from a companion star that the black hole is consuming. The matter falls in circles toward the black hole, like water down a drain, and forms a gigantic flat disk that accelerates particles within, causing them to discharge energy. As yet scientists have only a vague notion of how the entire process works.
