Gamma-ray Burst Found To Be Most Energetic Event in Universe

A team of astronomers from the California Institute of Technology announced today that a recently detected cosmic gamma-ray burst was as bright as the rest of the universe, releasing a hundred times more energy than previously theorized.

Physicists create first nanometer-scale mechanical charge detector

PASADENA—Wristwatch cellular phones and space probes the size of baseballs would certainly have some eager customers, but both are still the stuff of science fiction.

Nonetheless, physicists are making strides these days in the sort of miniaturization that could someday make tiny electromechanical devices a reality. One such milestone, the first nanometer-scale mechanical charge detector, is reported in the current issue of Nature.

ACE Satellite Now In Place Between Earth and Sun; Will Seek To Determine What Sun Is Made Of

ACE satellite will be a benefit to weather forecasters in predicting solar flares as well as to astrophysicists in understanding the nature of the universe.

Black Hole That Periodically Ejects Its Inner Disk As Jets Discovered

Astronomers observing a disk of matter spiralling into a black hole in our galaxy have discovered that the black hole periodically hurls the inner portion of the disk into space as jets travelling at near the speed of light.

Caltech Astrophysicist Charles Steidel Receives $500,000 Packard Foundation Fellowship

A Caltech astrophysicist who searches for the oldest and most distant structures in the universe has been named a recipient of a $500,000 grant from the David and Lucile Packard Foundation. Caltech Astrophysicist Charles Steidel Receives $500,000 Packard Foundation Fellowship October 1997 97

Astronomers Detect Relativistically Expanding Clouds Around the May 8 Gamma-Ray Burst

Astrophysicists still don't know what caused the gamma-ray burst of May 8, but they now have a size and rate of expansion for its remnant "fireball" to add to the location and distance.

Possible Planet-Forming Disk imaged by Caltech Radio Astronomers

A giant disk of gas and dust over 10 times the size of our own solar system has been detected rotating around a young star in the constellation of Auriga. Possible Planet-Forming Disk imaged by Caltech Radio Astronomers August 1997 97

Caltech Astronomers Crack the Puzzle of Cosmic Gamma-Ray Bursts

A team of Caltech astronomers has pinpointed a gamma-ray burst several billion light-years away from the Milky Way. The team was following up on a discovery made by the Italian/Dutch satellite BeppoSAX.

Caltech Astronomer Obtains Data That Could Resolve the "Age Problem"

Dr. Neill Reid, using information collected by the European Space Agency's Hipparcos satellite, has determined that a key distance measure used to compute the age of certain Milky Way stars is off by 10 to 15 percent. The new data leads to the conclusion that the oldest stars are actually 11 to 13 billion years old, rather than 16 to 18 billion years old, as had been thought.
