John P. Millis, Ph.D. for redOrbit.com - Your Universe Online There is perhaps no field of astronomical research that more captivates our attention than the search for planets outside our solar system. In the last two decades the planet hunting community has exploded, with hundreds of new planets and planet candidates emerging each year. The holy grail, of course, would be the detection of an Earth-like world. Specifically, astronomers are looking for a planet of similar size to our...

Using supercomputers to understand the super stars of the cosmos Is it a high-speed graphic animation of a yellow-golden cauliflower erupting in fast motion? No. Maybe it's some kind of time-lapse, computer-generated X-ray of a brain as it grows over years. No. It's one of many images Princeton University astrophysicist Adam Burrows has conjured up, using supercomputers to simulate an explosion deep within a star called a supernova. It's not a run-of-the-mill thermonuclear explosion that...

by Kitta MacPherson, Princeton University For scientists, supernovae are true superstars -- massive explosions of huge, dying stars that shine light on the shape and fate of the universe. For a brief burst of time, supernovae can radiate more energy than the sun will emit in its lifetime. With the potential energy of 25 hundred trillion trillion nuclear weapons, they can outshine entire galaxies, producing some of the biggest explosions ever seen, and helping track distances across the...

Scientists have made the astonishing discovery that sound might drive supernovae explosions. Their computer simulations say that dying stars pulse at audible frequencies -- for instance, at about the F-note above middle C -- for a split second before they blow up. Researchers in the 1960s began using computer models to test ideas about what, exactly, causes stars to explode. But mathematical simulations have so far failed to satisfactorily explain the inner workings of nature's most...

  • A unit of saved energy.
Coined by Amory Lovins, chairman of the Rocky Mountain Institute as a contraction of negative watt on the model of similar compounds like megawatt.
