Mirror, Mirror... [14 Dec 1997] - A new type of X-ray mirror that allows images to be made from higher energy
radiation than ever before has recently completed testing at NASA's Goddard
Space Flight Center, Greenbelt, MD.

The Yell of a Black Hole [04 Dec 1997] - How fast are
black holes at the centers of distant galaxies swallowing the matter around them? Using
observations from the Japanese/NASA Advanced Satellite for Cosmology and
Astrophysics (ASCA), Paul Nandra, Richard Mushotzky, and their
research team have begun to shed some light on this question.

Einstein Passes Another Test [07 Nov 1997] - Astronomers using NASA's Rossi X-ray Timing Explorer (RXTE)
spacecraft reported on November 6 that they have observed a black hole
that is literally dragging space and time around itself as it
rotates. This bizarre effect, called "frame dragging," is the
first evidence to support a prediction made in 1918 using
Einstein's Theory of Theory of Relativity.

The Milky Way Blows Bubbles ?! [07 May 1997] - Astronomers using the NASA's Compton Gamma-Ray Observatory (CGRO) satellite to
map the distribution of antimatter in the Milky Way Galaxy were
surprised to find what appears to be a large antimatter
bubble being blown upward from the center of our Galaxy.

Look, There in the Sky! It's a Gamma-Ray Burster? [27 Mar 1997] - What exactly is the source of a gamma-ray burst? Since their
discovery in the early 1970s, nobody has been able to explain the cause of the
mysterious flash of gamma-rays called a gamma-ray burst that seems to come
from a random direction on the sky. Worse yet, it is even unclear whether
these high-energy explosions originate in our own Galaxy or in distant
galaxies across the Universe. Now, all of that may have changed!

Reboosting the Compton Gamma-Ray Observatory [18 Feb 1997] - The Compton Gamma-Ray Observatory (CGRO) has been in Earth orbit for nearly
six years now. In that time, observations from its 4-instrument complement
have greatly expanded our understanding of the most energetic objects in the
Universe.
