MOA 2002-BLG-33
(Preview)
Fifty years after his death, Albert Einstein's work still provides new tools for understanding our universe. An international team of astronomers has now used a phenomenon first predicted by Einstein in 1936, called gravitational lensing, to determine the shape of stars. This phenomenon, due t...

GRB050525
(Preview)
The Spitzer Space Telescope executed its first-ever High Impact Target of Opportunity (ToO) observation in order to catch a look at the aftermath of one of the most violent explosions in the universe.
The ToO program was designed as a means to interrupt Spitzer's normal observation sche...
