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.
Future Mission Gets Stellar Name |
[22 Oct 1997] - The Next Generation X-ray Observatory called the High Throughput X-ray
Spectroscopy (HTXS) mission has been renamed the Constellation Mission.
A New Dark Matter Discovery |
[23 July 1997] - X-ray observations by of the celestial object MG2026+112 have given
scientists a new puzzle to solve....and great clues to help them do it!
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
