GRB 080916C

Gamma ray bursts are the brightest explosions we see in the Universe. The farthest known GRB occurred 12.2 billion light-years away in the constellation Carina. The explosion that created GRB 080916C contained the power of 9,000 supernovae. This very short movie shows Fermi Large Area Telescope observations of GRB 080916C. About 8 minutes of data are compressed into 6 seconds. The colored dots represent gamma rays of different energies. The blue dots represent lower-energy gamma rays; green, moderate energies; and red, the highest energies.

Gamma Ray Burst

When a massive star collapses to form a black hole, a burst of gamma rays results as particles are blasted outward at nearly the speed of light. This animation shows the most common type of gamma-ray burst. An end-on view of a jet greatly boosts its apparent brightness. One especially bright burst (GRB 130427A) was detected in 2013 by the Fermi and Swift satellites. A Fermi image of that burst ends the animation sequence.

Swift’s Gamma Ray Burst Number 1,000

grb151027b_uvot_xrt_labeled_2160GRB 151027B, Swift‘s 1,000th burst, is in the center of this composite X-ray, ultraviolet, and optical image. X-rays were captured by Swift‘s X-Ray Telescope within minutes after the Burst Alert Telescope detected the blast. Swift‘s Ultraviolet/Optical Telescope (UVOT) began observations a few seconds later and faintly detected the burst in visible light. The image includes X-rays with energies from 300 to 6,000 eV, mostly from the burst, and lower-energy light seen through the UVOT’s visible, blue and ultraviolet filters (color shifted, respectively, to red, green and blue).
