Astronomers gain clues about fundamental physics
An international team of astronomers has looked at something very big -- a distant galaxy -- to study the behavior of things very small -- atoms and molecules -- to gain vital clues about the fundamental nature of our entire Universe. The team used the National Science Foundation's Robert C. Byrd Green Bank Telescope (GBT) to test whether the laws of nature have changed over vast spans of cosmic time.

Saturday will be one second longer than usual -- A "leap second" will be added to the world's clocks at 23 hours, 59 minutes and 59 seconds Coordinated Universal Time (UTC) Saturday. This corresponds to 6:59:59 p.m. EST, when the extra second will be inserted at the U.S. Naval Observatory. This marks the 23rd leap second to be added to UTC, a uniform time-scale kept by atomic clocks around the world.

Also puzzling is the equatorial ridge that bisects this terrain, and how it fits into the story of the moon's strange brightness dichotomy. The ridge is seen here, curving along the lower left edge of Iapetus.

Old stars and mysterious cosmic explosions linked
Cosmic gamma-ray bursts, the most powerful explosions in the universe, have the extreme brilliance of a billion billion Suns and occur several times a day. But they are not all created equal.
