Blue indicates where NuSTAR has made the first resolved image ever of this source at the highest energy X-ray light, between 10 and 20 kiloelectron volts. Red and green show the lower end of NuSTAR's energy range, which overlaps with NASA's high-resolution Chandra X-ray Observatory. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/CassA_NuStar/CassA_NuStar.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/FNAL-Linsley-Volcano-Ranch/FNAL-Linsley-Volcano-Ranch.dc.xml (Left) John Linsley at Volcano Ranch. On February 22, 1962, Linsley observed an air shower created by a primary particle with an energy greater than 1020 eV, the highest energy cosmic ray observed up to that point. If a particle of this energy was created within the galaxy, it could not be contained in the galaxy. Linsley’s observations at Volcano Ranch suggested that not all cosmic rays are confined within the galaxy, as had been previously supposed. (Right) The plan of Volcano Ranch array in 1962, as it looked when Linsley made his observation. The circles represent 3.3 m2 scintillation detectors. Numbers near circles are shower densities (particles/m2) registered in the event. Point 'A' is the estimated location of the shower core. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/FNAL-Linsley-Volcano-Ranch/FNAL-Linsley-Volcano-Ranch.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/GPN-2000-000451/GPN-2000-000451.dc.xml Jupiter and its four planet-sized moons, called the Galilean satellites, were photographed in early March 1979 by Voyager 1 and assembled into this collage. Io is the moon in the upper left corner of the image, and is the moon that is closest to Jupiter. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/GPN-2000-000451/GPN-2000-000451.dc.xml Thu, 01 Mar 1979 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/GRB090423/GRB090423.dc.xml One for the record books, gamma-ray burst 090423 was detected April 23, 2009, by the Swift Gamma-Ray Burst Explorer mission. 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-OSO-3-GC/NASA-OSO-3-GC.dc.xml Scale drawing of the OSO 3 detector. Inset is a picture of the satellite. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/NASA-OSO-3-GC/NASA-OSO-3-GC.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/atom-bomb-test/atom-bomb-test.dc.xml 1/40th of a second after detonation at the Trinity site in New Mexico. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/atom-bomb-test/atom-bomb-test.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/cgro-with-batse-diagram/cgro-with-batse-diagram.dc.xml The BATSE detector module identified gamma ray bursts based on an increase in the detection of gamma rays as compared to the background noise. The illustration on the left is an artists rendering of the Compton Gamma Ray Observatory indicating the location of the BATSE detectors on the observatory. The diagram on the right illustrates how one of the eight detectors look. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/cgro-with-batse-diagram/cgro-with-batse-diagram.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/grb050709/grb050709.dc.xml Gamma-ray bursts longer than two seconds are the most common type and are widely thought to be triggered by the collapse of a massive star into a black hole. As matter falls toward the black hole, some of it forms jets in the opposite direction that move near the speed of light. These jets bore through the collapsing star along its rotational axis and produce a blast of gamma rays after they emerge. This artist's rendering depicts a GRB that was discovered on July 9, 2005, by NASA's High-Energy Transient Explorer (HETE). http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/grb050709/grb050709.dc.xml Sat, 09 Jul 2005 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/grb970228_hubble/grb970228_hubble.dc.xml It is difficult to determine the origin of a GRB, but sometimes it can be done. The visible light of this GRB was detected by ground-based telescopes, and once the light had faded a deep picture by the Hubble showed this GRB was located in a faint distant galaxy http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/grb970228_hubble/grb970228_hubble.dc.xml Fri, 05 Sep 1997 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/grb980425/grb980425.dc.xml The ESO 184-G82 galaxy has loose spiral arms with many bright regions where stars are forming. The inset shows an expanded view of one of the star-forming regions. The arrow shows the location the 1998 supernova explosion. This supernova was also a gamma ray source, showing supernova are the origin of some GRB's. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/grb980425/grb980425.dc.xml Mon, 12 Jun 2000 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/mwmw_8x10/mwmw_8x10.dc.xml Imagine that you are looking up at the night sky and can see the arms of the Milky Way Galaxy bisecting the sky. The image of the sky labelled optical in this graphic is what you would see with your eyes. Now, observe the images of the same view of the Milky Way, but in through the lens of a telescope that sees in a different wavelength than our eyes. The amount and type of information, or data, available in each waveband varies as illustrated in this graphic. You can see why it is so important that we look at the universe through eyes that see wavebands other than optical light. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/mwmw_8x10/mwmw_8x10.dc.xml Thu, 01 Jan 1970 12:00:00 GMT
