MIT team achieves coldest temperature ever
Source: MIT Posted: 9/27/03
MIT scientists have cooled a sodium gas to the lowest temperature ever recorded -- only half-a-billionth of a degree above absolute zero. The work, to be reported in the Sept. 12 issue of Science, bests the previous record by a factor of six, and is the first time that a gas was cooled below 1 nanokelvin (one-billionth of a degree).

Hurricane Isabel From Space

If you happened to be in North Carolina, the sight of advancing Hurricane Isabel was surely unwelcome. From space, though, it was a thing of beauty. NASA's Terra satellite took this picture at 11:50 a.m. EDT on Sept. 18th.

If you've been listening to the news for the past two months you've undoubtedly heard a lot about Mars. Mars. Mars. Mars. And just maybe, you're getting sick of Mars. Good news: There are eight other planets in the solar system. And this week you can see the two biggest ones.

Chandra 'hears' a black hole
Source: NASA Posted: 9/10/03
NASA's Chandra X-ray Observatory detected sound waves, for the first time, from a super-massive black hole. The "note" is the deepest ever detected from an object in the universe. The tremendous amounts of energy carried by these sound waves may solve a longstanding problem in astrophysics.

Matchbox-sized Atomic Clock

In October 2003 the Office of Naval Research will unveil the performance of the next-generation, super-accurate clock no bigger than a matchbox. The Ultra-miniature Rubidium (Rb) Atomic Clock, 40 cubic centimeters in volume and using a minuscule one watt of power, doesn’t weigh much more than a matchbox either.
