The Spitzer Infrared Nearby Galaxies Survey (SINGS) was a survey of 75 galaxies using the Spitzer Space Telescope, carried out between 2003 and 2006.
One of the telescope's six Legacy Science Projects, SINGS collected a comprehensive set of spectroscopic data in the infrared region, which, in conjunction with measurements at other wavelengths, was intended to provide insights into star formation and other processes occurring within these galaxies.

The M81 Group is a galaxy group in the constellations Ursa Major and Camelopardalis that includes the galaxies Messier 81 and Messier 82, as well as several other galaxies with high apparent brightnesses. The approximate center of the group is located at a distance of 3.6 Mpc, making it one of the nearest groups to the Local Group. The group is estimated to have a total mass of ×1012M☉. The M81 Group, the Local Group, and other nearby groups all lie within the Virgo Supercluster.
A space telescope or space observatory is a telescope in outer space used to observe astronomical objects. Suggested by Lyman Spitzer in 1946, the first operational telescopes were the American Orbiting Astronomical Observatory, OAO-2 launched in 1968, and the Soviet Orion 1 ultraviolet telescope aboard space station Salyut 1 in 1971. Space telescopes avoid the filtering and distortion (scintillation) of electromagnetic radiation which they observe, and avoid light pollution which ground-based observatories encounter. They are divided into two types: Satellites which map the entire sky, and satellites which focus on selected astronomical objects or parts of the sky and beyond. Space telescopes are distinct from Earth imaging satellites, which point toward Earth for satellite imaging, applied for weather analysis, espionage, and other types of information gathering.
Infrared astronomy is a sub-discipline of astronomy which specializes in the observation and analysis of astronomical objects using infrared (IR) radiation. The wavelength of infrared light ranges from 0.75 to 300 micrometers, and falls in between visible radiation, which ranges from 380 to 750 nanometers, and submillimeter waves.

The Infrared Astronomical Satellite or in Dutch: Infrarood Astronomische Satelliet (IRAS) was the first space telescope to perform a survey of the entire night sky at infrared wavelengths.
The Spitzer Space Telescope, formerly the Space Infrared Telescope Facility (SIRTF), is an infrared space telescope launched in 2003 and retired on 30 January 2020.
NASA's series of Great Observatories satellites are four large, powerful space-based astronomical telescopes launched between 1990 and 2003. They were built with different technology to examine specific wavelength/energy regions of the electromagnetic spectrum: gamma rays, X-rays, visible and ultraviolet light, and infrared light.
The Westerbork Synthesis Radio Telescope (WSRT) is an aperture synthesis interferometer built on the site of the former World War II Nazi detention and transit camp Westerbork, north of the village of Westerbork, Midden-Drenthe, in the northeastern Netherlands.
An astronomical survey is a general map or image of a region of the sky that lacks a specific observational target. Alternatively, an astronomical survey may comprise a set of images, spectra, or other observations of objects that share a common type or feature. Surveys are often restricted to one band of the electromagnetic spectrum due to instrumental limitations, although multiwavelength surveys can be made by using multiple detectors, each sensitive to a different bandwidth.
Robert Charles Kennicutt, Jr. FRS is an American astronomer. He is a former Plumian Professor of Astronomy at the Institute of Astronomy in the University of Cambridge. He was formerly Editor-in-Chief of the Astrophysical Journal (1999–2006) and became a co-editor of the Annual Review of Astronomy and Astrophysics as of 2021. His research interests include the structure and evolution of galaxies and star formation in galaxies.
Wide-field Infrared Explorer was a NASA satellite launched on 5 March 1999, on the Pegasus XL launch vehicle into polar orbit between 409 and 426 km above the surface of Earth. WIRE was intended to be a four-month infrared survey of the entire sky at 21-27 µm and 9-15 µm, specifically focusing on starburst galaxies and luminous protogalaxies.
Luminous infrared galaxies or LIRGs are galaxies with luminosities, the measurement of brightness, above 1011 L☉. They are also referred to as submillimeter galaxies (SMGs) through their normal method of detection. LIRGs are more abundant than starburst galaxies, Seyfert galaxies and quasi-stellar objects at comparable luminosity. Infrared galaxies emit more energy in the infrared than at all other wavelengths combined. A LIRG's luminosity is 100 billion times that of our sun.
A low-ionization nuclear emission-line region (LINER) is a type of galactic nucleus that is defined by its spectral line emission. The spectra typically include line emission from weakly ionized or neutral atoms, such as O, O+, N+, and S+. Conversely, the spectral line emission from strongly ionized atoms, such as O++, Ne++, and He+, is relatively weak. The class of galactic nuclei was first identified by Timothy Heckman in the third of a series of papers on the spectra of galactic nuclei that were published in 1980.
Frank James Low was a solid state physicist who became a leader in the new field of infrared astronomy, after inventing the gallium doped germanium bolometer in 1961. This detector extended the range of the observable spectrum to much longer wavelengths.
An infrared telescope is a telescope that uses infrared light to detect celestial bodies. Infrared light is one of several types of radiation present in the electromagnetic spectrum.

The Great Observatories Origins Deep Survey, or GOODS, is an astronomical survey combining deep observations from three of NASA's Great Observatories: the Hubble Space Telescope, the Spitzer Space Telescope, and the Chandra X-ray Observatory, along with data from other space-based telescopes, such as XMM Newton, and some of the world's most powerful ground-based telescopes.
George Henry Rieke, a noted American infrared astronomer, is former Deputy Director of the Steward Observatory and Regents Professor of Astronomy and Planetary Sciences at the University of Arizona in Tucson. He led the experiment design and development team for the Multiband Imaging Photometer for Spitzer (MIPS) instrument on NASA's infrared Spitzer Space Telescope, and currently chairs the science team of the Mid-Infrared Instrument for the James Webb Space Telescope.
Marcia Jean Rieke is an American astronomer. She is a Regents' Professor of Astronomy and associate department head at the University of Arizona. Rieke is the Principal Investigator on the near-infrared camera (NIRCam) for the James Webb Space Telescope (JWST). She has also served as the deputy-Principal Investigator on the Near Infrared Camera and Multi-Object Spectrometer (NICMOS) for the Hubble Space Telescope (HST), and as the co-investigator for the multiband imaging photometer on the Spitzer Space Telescope, where she also acted as an outreach coordinator and a member of the Science Working Group. Rieke was also involved with several infrared ground-based observatories, including the MMT Observatory in Arizona. She was vice chair for Program Prioritization of the Astro2010 Decadal Survey Committee, "New Worlds, New Horizons". Marcia Rieke is considered by many to be one of the "founding mothers" of infrared astronomy, along with Judith Pipher.
