Gamma-Ray Bursts Active Longer than Previously Thought
The X-ray Telescope on NASA's Swift satellite captured the intensity of a bright X-flare from GRB 060714. The elongated blue and gray regions are an artifact of the image processing (left). After the flare, (right) the GRB's X-ray emission faded considerably, revealing a faint afterglow. Click image to enlarge. Credit: NASA / Swift / XRT Science Team.
Gamma-Ray Birth Cries Suggest Massive Magnetic Engines
The core of a massive star in a distant galaxy collapses, ending its life — though there is little effect visible at the surface. Deep inside, twin beams of matter and energy begin to blast their way outward. (Image Credit: NASA/Swift/Sonoma State University/A. Simonnet)
Discovery Reveals that Distant Quasars Live in Massive Dark-Matter Halos
