Astronomers Test Einstein in a New Regime Using Pair of Burnt-Out Stars
The white dwarf stars are so close together that they make a complete orbit in less than 13 minutes.

Astronomers have discovered the most massive black holes to date — two monsters weighing as much as 10 billion suns and threatening to consume anything, even light, within a region five times the size of our solar system.
A team of researchers has used NASA's Kepler space telescope to discover an unusual multiple-planet system containing a super-Earth and two Neptune-sized planets orbiting in resonance with each other.
Conventional solar cell efficiency could be increased from the current limit of 30 percent to more than 60 percent, suggests new research on quantum dots led by chemist Xiaoyang Zhu.
A century after Albert Einstein said we would never be able to observe the instantaneous velocity of tiny particles as they randomly shake and shimmy, so called Brownian motion, physicist Mark Raizen and his group have done so.
