Nov 30, 2011 - NASA's Swift Finds a Gamma-Ray Burst With a Dual Personality
A peculiar cosmic explosion first detected by NASA's Swift observatory on Christmas Day 2010 was caused either by a novel type of supernova located billions of light-years away or an unusual collision much closer to home, within our own galaxy. Papers describing both interpretations appear in the Dec. 1 issue of the journal Nature.

Nov 10, 2011 - NASA's Swift Observatory Catches Asteroid Flyby
As asteroid 2005 YU55 swept past Earth in the early morning hours of Wednesday, Nov. 9, telescopes aboard NASA's Swift satellite joined professional and amateur astronomers around the globe in monitoring the fast-moving space rock. The unique ultraviolet data will aid scientists in understanding the asteroid's surface composition.

Oct 25, 2011 - Now There's an App for the Swift Observatory
Interested in the latest discoveries of NASA's Swift satellite? The Swift team has released a free iPhone application that gives you the details of all the latest gamma-ray-burst discoveries that the Swift observatory is making throughout the universe. The app also allows users to track, in real time, the location of Swift as it orbits the Earth, to see where Swift is pointed right now, and to view an informative gallery of beautiful images obtained by the Swift satellite.

Aug 24, 2011 - Researchers Detail How A Distant Black Hole Devoured A Star
Two studies appearing in the Aug. 25 issue of the journal Nature provide new insights into a cosmic accident that has been streaming X-rays toward Earth since late March. NASA's Swift satellite first alerted astronomers to intense and unusual high-energy flares from the new source in the constellation Draco.

Jun 10, 2011 - Nearby Galaxy Boasts Two Monster Black Holes, Both Active
A study using NASA's Swift satellite and the Chandra X-ray Observatory has found a second supersized black hole at the heart of an unusual nearby galaxy already known to be sporting one.

Apr 28, 2011 - NASA's Swift and Hubble Probe Asteroid Collision Debris
Late last year, astronomers noticed an asteroid named Scheila had unexpectedly brightened, and it was sporting short-lived plumes. Data from NASA's Swift satellite and Hubble Space Telescope showed these changes likely occurred after Scheila was struck by a much smaller asteroid.

Apr 07, 2011 - Breakthrough Study Confirms Cause Of Short Gamma-Ray Bursts
A new supercomputer simulation shows the collision of two neutron stars can naturally produce the magnetic structures thought to power the high-speed particle jets associated with short gamma-ray bursts (GRBs). The study provides the most detailed glimpse of the forces driving some of the universe's most energetic explosions.

Apr 07, 2011 - NASA Telescopes Join Forces to Observe Unprecedented Explosion
NASA's Swift, Hubble Space Telescope and Chandra X-ray Observatory have teamed up to study one of the most puzzling cosmic blasts yet observed. More than a week later, high-energy radiation continues to brighten and fade from its location.

Jan 20, 2011 - Swift Survey Finds 'Missing' Active Galaxies
Seen in X-rays, the entire sky is aglow. Even far away from bright sources, X-rays originating from beyond our galaxy provide a steady glow in every direction. Astronomers have long suspected that the chief contributors to this cosmic X-ray background were dust-swaddled black holes at the centers of active galaxies. The trouble was, too few of them were detected to do the job
