The image is a composite of data from UVOT and XRT. The image is fuzzy because XRT does not have high enough resolution to produce sharp images. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/GRB090423/GRB090423.dc.xml Thu, 23 Apr 2009 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/NASA-Fermi-Map/NASA-Fermi-Map.dc.xml This all-sky image made in 2011 was constructed using two years of observations by NASA's Fermi Gamma-ray Space Telescope. It shows how the sky appears at energies greater than 1 billion electron volts (1 GeV). Brighter colors indicate brighter gamma-ray sources. A diffuse glow fills the sky and is brightest along the plane of our galaxy (middle). Discrete gamma-ray sources include pulsars and supernova remnants within our galaxy, as well as distant galaxies powered by supermassive black holes. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/NASA-Fermi-Map/NASA-Fermi-Map.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/firstgrb_vela4/firstgrb_vela4.dc.xml Gamma-ray bursts (GRBs) are sudden outbursts of gamma rays from a particular place in the sky that last a few seconds or so. These outbursts are similar to what is seen in a nuclear bomb explosion, and the first GRBs were detected by the Vela satellites that monitored nuclear testing. This graph shows the sudden increase in gamma rays recorded for the first GRB detected by the monitoring satellites in 1967. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/firstgrb_vela4/firstgrb_vela4.dc.xml Sun, 02 Jul 1967 12:00:00 GMT
