To be clear, all the colors mentioned may not be easily discernible because of how scientists overlay certain bits of information. The latter two show debris of the destroyed star. In this image, Chandra data is seen in blue and shows a "powerful blast wave that ripped through space after the detonation," NASA explains, while infrared data from Spitzer is seen in red, and optical light from the Hubble Space Telescope is seen in cyan and yellow. Someday, our sun will become a white dwarf as well. White dwarfs are the dying cores of stars that once thrived and shined the way our sun currently does. NASA then moves on to Kepler's Supernova Remnant, which the agency says represents the remains of a white dwarf that exploded after undergoing a thermonuclear explosion.

That was humanity's second black hole image). (The EHT team did eventually manage to get an image of Sgr A*. It was easier to inspect the center of a galaxy that we can see panoramically. This internal perspective is actually one reason scientists with the Event Horizon Telescope Collaboration selected M87*, the black hole in one of our neighboring galaxies, as the subject of humanity's first black hole image instead of Sgr A*, the one in the center of the Milky Way. The reason it looks kind of blobby instead of swirly like you might imagine a galactic center to look is due to the fact that we are looking at it from within the galaxy. It contains a supermassive black hole, superheated clouds of gas, neutron stars (which are stellar beings so dense a tablespoon of one would equal something like the weight of Mount Everest) and other trippy things. The first image NASA highlights in a statement about the five pieces is titled the "Galactic Center." Sitting about 26,000 light-years from Earth, this is literally the center of the Milky Way galaxy that we live in. 2) an imaging photometer, with three detector arrays imaging at 24, 70, and 160 microns (one array will also take low-resolution spectra at 50 - 100 microns) 3) a spectrograph providing high- and low-resolution spectroscopy at mid-infrared wavelengths (5 - 40 microns).Now that we know what we're looking at, let's go through the lot. The instruments selected include: 1) a four-channel infrared array camera imaging at 3.6, 4.5, 5.8, and 8 microns. The telescope has an 85 cm diameter aperture. The Spitzer telescope is a lightweight reflector of Ritchey-Chrétien design. Spitzer has an Earth-trailing Heliocentric orbit. The pointing control subsystem employs a celestial-inertial, three-axis stabilized control system. The spacecraft consists of an octagonal bus structure, and a solar array to power the science instruments. Spitzer will study a wide variety of astronomical phenomena, extending from our Solar System to the distant reaches of the early Universe. The science capabilities include imaging/photometry at 3 - 180 microns, spectroscopy at 5 - 40 microns, and spectrophotometry at 50 - 100 microns. The observatory is the final element in NASA's Great Observatories Program. The Spitzer Space Telescope (formerly SIRTF, the Space Infrared Telescope Facility) is a 0.85-meter telescope with three cryogenically cooled instruments, operating in the 3 - 180 micron range. ![]()
