The Universe to 1-Percent Accuracy
Topic: Cosmic Evolution
01/14/14
The Baryon Oscillation Spectroscopic Survey (BOSS) has measured the scale of the universe to an accuracy of one percent. This and future measures at this precision are the key to determining the nature of dark energy.

NASA's Fermi Makes First Gamma-ray Study of a Gravitational Lens
Topic: Cosmic Evolution
01/13/14
An international team of astronomers, using NASA's Fermi observatory, has made the first-ever gamma-ray measurements of a gravitational lens, a kind of natural telescope formed when a rare cosmic alignment allows the gravity of a massive object to bend and amplify light from a more distant source.

Challenging General Relativity
Topic: Cosmic Evolution
01/11/14
Astronomers have found a system with three stars that are packed tightly into a space smaller than Earth's orbit. This unique system is helping scientists study the nature of gravity.
