1997

Link to article 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.


Link to article 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.


Link to article 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.


Link to article 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.


Link to article 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!


Link to article 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.


Link to article 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!


Link to article 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.
