Black Hole That Periodically Ejects Its Inner Disk As Jets Discovered

Robert Tindol

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.

Geophysicists Develop Model to Describe Huge Gravity Anomaly of Hudson Bay Region

Robert Tindol

Using a new approach to analyzing planetary gravity fields, two geophysicists, Mark Simons at the California Institute of Technology and Bradford Hager at M.I.T., have shown that incomplete glacial rebound can account for a substantial portion of the Hudson Bay gravity anomaly.

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

Robert Tindol

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.

Caltech Astronomers Crack the Puzzle of Cosmic Gamma-Ray Bursts

Robert Tindol

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"

Robert Tindol

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.
