Astrophysicists find cause for galactic superbubble
A gigantic empty void in our own galaxy was caused by a cluster of massive young stars at its centre, says a University of Toronto astrophysics professor. (1999-07-27)

Press Advisory: Inner Space/Outer Space II Symposium
The Inner Space/Outer Space II Symposium will be held at Fermilab, May 26-29, 1999. (1999-05-13)

Ten Young Researchers Each Awarded $1 Million By McDonnell Foundation
(St. Louis, MO) - Ten early career researchers, whose work could shape our knowledge of the world around us, are now each the recipient of a $1 million research fellowship awarded to their sponsoring institution, by the McDonnell Foundation. (1999-01-28)

Gamma-Ray Bursts: Spindown Of Cosmic Flywheels
A conclusive explanation for the origin of Gamma-Ray Bursts (GRB) as electromagnetic braking of a rapidly rotating neutron star has been developed at the Max Planck Institute for Astrophysics in Garching/Germany (Astronomy & Astrophysics, Vol. 341, Issue 1, L1 - L4). (1998-12-03)

"Mirage" Used To Measure Age Of Universe
An international team led by a young Australian scientist has used CSIRO's Australia Telescope to measure how fast the Universe is expanding-and found it to be both older and larger than previously thought. (1998-12-01)

Astrophysicists Use Virtual Reality To Chase Earth's Tail
Astrophysicists at the University of Warwick are using a 3D virtual reality system to research the Earth's electromagnetic tail. (1998-11-12)

Scientists Begin To Tease Out A Hidden Star's Secrets
Peering deep inside obscuring cocoons of stardust, astronomers are beginning to witness the birthing secrets of an unusual star. (1998-07-24)

NASA X-Ray Observatory Completes Tests Under Harsh Simulated Space Conditions
NASA's most powerful X-ray observatory has successfully completed a month-long series of tests in the extreme heat, cold, and airless conditions it will encounter in space during its five-year mission to shed new light on some of the darkest mysteries of the universe. (1998-07-08)

"Nearby" Galaxy Clusters May Still Be Birthing New Stars
Astronomers have found newer, bluer galaxies than expected in nearby galaxy clusters, suggesting broods of young stars in these galaxies. The finding shows that star formation from galactic gas and dust in these clusters has occurred much more recently than astronomers had thought -- and may be an ongoing process. (1998-06-09)

Why Neutron Stars And White Dwarfs Rotate: Kicks At Birth, Not Inheritance
Scientists at the Max Planck Institute for Astrophysics and at Caltech explain in (1998-05-26)

Gamma-Ray Burst Identification Earns Top Prize
Dr. Jan van Paradijs of the University of Alabama in Huntsville and The University of Amsterdam last week shared in the Bruno Rossi prize awarded annually by the American Astronomical Society (1998-01-12)

With Space Telescope And Model, Star's Birth Pains Revealed
Using a potent combination of observation and theory, astronomers are peeling away layers of cosmic dust to see the birth pains of sun-like stars. (1998-01-07)

NASA Experiment Detects 2000th Cosmic Burst Of Gamma Rays
2000 arrived a little early for astrophysicists at NASA's Marshall Space Flight Center. Not the year, but the 2000th gamma-ray burst recorded by the Burst and Transient Source Experiment aboard the Compton Gamma Ray Observatory. Each of these enigmatic explosions is thought to release more energy in 10 seconds than our Sun will emit in its entire 10-billion year lifetime. (1997-12-15)

Astrophysicists Solve Mystery Of Gas Flow From Sunspots
One of the classic problems of solar physics has been solved, and the solution turns out to be a model of solar gas flow first proposed by a University of Rochester astrophysicist in 1988. In a paper to appear in the December 4 issue of Nature, John H. Thomas presents a more realistic version of the siphon-flow model, which predicts how gas flows from sunspots into the solar atmosphere. (1997-12-03)

USMP-4 Closes With A Bit Of Astrophysics - Mission Prepares To Return Home
Most experiments on board the Shuttle are shutting down in preparation for landing early Friday morning. The dendritic growth experiment remains active, and scientists are measuring cosmic ray and background radiation effects within the Shuttle which will be used to interpret results of the confined helium experiment. Data gathered has exceeded expectations. One furnace unexpectedly shut down early. (1997-12-03)

Two New Moons Of Uranus Discovered
A team of scientists led by a University of Toronto astronomer has discovered two distant moons orbiting around the planet Uranus. (1997-10-31)

NEAR Gets Unexpected View Of Mysterious Gamma-Ray Bursts
The NEAR spacecraft, designed to study asteroids, has been reconfigured in mid-flight to help track down mysterious bursts of gamma-ray radiation. (1997-10-01)

New Gamma-rays Count Challenges Astronomical Theories
Scientists have discovered recently that there are fewer low-energy photons in the universe than previously thought, an observation that may alter the way astronomers think about how galaxies were formed. The results were presented April 18 at the meeting of the American Physical Society in Washington, D.C (1997-04-19)

New Signature Of Black Holes Detected?
X-ray observations of a new black hole candidate contain what appears to be a unique signature predicted three years ago by physics Professor Robert V. Wagoner's astrophysics group at Stanford University. The signature may allow scientists to determine the mass and rotation rate of black holes with an unprecedented level of accuracy. (1997-01-14)

NASA Turns Over Satellite Operations To UC Berkeley
NASA's Goddard Space Flight Center and UC Berkeley's Center for Extreme Ultraviolet Astrophysics have forged an innovative partnership that for the first time would transfer day-to-day operations of one of NASA's satellites to a university (1996-09-26)

ORNL Facility May Help Solve Stellar Mysteries
Researchers at the Oak Ridge National Laboratory on August 30 generated the first radioactive ion beam at the Holifield Radioactive Ion Beam Facility. Researchers from around the world soon will begin using this facility to study nuclei that cannot be produced from elements that exist on Earth (1996-08-30)
