Random information on the term “AURA”:
The Association of Universities for Research in Astronomy (AURA) is a consortium of universities and other institutions that operates astronomical observatories and telescopes. AURA recognizes its mission statement as “To promote excellence in astronomical research by providing access to state-of-the-art facilities.”
Founded October 10, 1957 with the encouragement of the National Science Foundation (NSF), AURA was incorporated by a group of seven U.S. universities: California, Chicago, Harvard, Indiana, Michigan, Ohio State, and Wisconsin. The first meeting of the Board of Directors took place in Ann Arbor, Michigan. Today, AURA has 39 member institutions in the United States and seven international affiliate members.
AURA began as a small organization dedicated to ground-based optical astronomy, managing a range of 1- to 4-meter telescopes and providing community advocacy for optical/infrared astronomy. Over the years, AURA expanded its focus to include Solar Astronomy and the Gemini 8-meter telescopes, going on to partner with other consortia such as WIYN (Wisconsin Indiana Yale & NOAO) and SOAR (Southern Astrophysical Research). In the 1980s, AURA took on the management of the Space Telescope Science Institute, opening up the ultraviolet, optical, and infrared wavelength bands in space with the Hubble Space Telescope. AURA is furthering its aims in infrared space astronomy through the James Webb Space Telescope (JWST).
Random information on the term “HALO”:
A halo (from Greek ἅλως, halōs; also known as a nimbus, aureole, glory, or gloriole) is a crown of light rays, circle or disk of light that surrounds a person in art. They have been used in the iconography of many religions to indicate holy or sacred figures, and have at various periods also been used in images of rulers or heroes. In the sacred art of Ancient Greece, Ancient Rome, Hinduism, Buddhism, Islam and Christianity, among other religions, sacred persons may be depicted with a halo in the form of a circular glow, or flames in Asian art, around the head or around the whole body—this last one is often called a mandorla. Halos may be shown as almost any colour or combination of colours, but are most often depicted as golden, yellow or white when representing light or red when representing flames.
Homer describes a more-than-natural light around the heads of heroes in battle. Depictions of Perseus in the act of slaying Medusa, with lines radiating from his head, appear on a white-ground toiletry box in the Louvre and on a slightly later red-figured vase in the style of Polygnotos, ca. 450-30 BC, in the Metropolitan Museum of Art. On painted wares from south Italy radiant lines or simple haloes appear on a range of mythic figures: Lyssa, a personification of madness; a sphinx; a sea demon; and Thetis, the sea-nymph who was mother to Achilles. The Colossus of Rhodes was a statue of the sun-god Helios and had his usual radiate crown (copied for the Statue of Liberty). Hellenistic rulers are often shown wearing radiate crowns that seem clearly to imitate this effect.[citation needed]
Random information on the term “CORONA”:
KH-5 ARGON was a series of reconnaissance satellites produced by the United States from February 1961 to August 1964. The KH-5 operated similarly to the Corona series of satellites, as it ejected a canister of photographic film. At least 12 missions were attempted, but at least 7 resulted in failure. The satellite was manufactured by Lockheed. Launches used Thor-Agena rockets flying from Vandenberg Air Force Base, with the payload being integrated into the Agena.
Different versions of the satellite varied in mass from 1150 kilograms to 1500 kg. At least two missions deployed ELINT subsatellites. Ground resolution for the satellite was 140 meters, with a swath of 556 km. The onboard camera had a focal length of 76 mm. The purpose of the system, which produced relatively low-resolution images compared to other spy satellites, was to provide imagery for mapmaking purposes. This was one of the tasks that had originally been planned for the Samos series of satellites equipped with the (quickly cancelled) “E-4” cameras. Each satellite took photographs for less than a week before returning its film.
