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/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/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
