493 Griseldis
Griseldis (minor planet designation: 493 Griseldis) is a fairly dark main-belt asteroid 46 km in diameter. Overview Griseldis is suspected of having been impacted by another asteroid in March 2015. Other asteroids suspected of an asteroid-on-asteroid impact include 354P/LINEAR and 596 Scheila which also showed extended features (tails). The asteroid was observed with the Subaru Telescope (8m), the Magellan Telescopes (6.5), and also the University of Hawaii 2.2 m telescope in early 2015. The activity was detected on the Subaru in late March, and confirmed on the Magellan telescope a few days later (which is in Chile), but no activity was seen by April. Also, no activity was seen in archived images from 2010 or 2012 according to a University of Hawaii press release.

Max Wolf
Maximilian Franz Joseph Cornelius Wolf (21 June 1863 – 3 October 1932) was a German astronomer and a pioneer in the field of astrophotography. He was the chairman of astronomy at the University of Heidelberg and director of the Heidelberg-Königstuhl State Observatory from 1902 until his death in 1932. Early life Max Wolf was born in Heidelberg, Germany on 21 June 1863, the son of medical doctor Franz Wolf. His father encouraged an interest in science and built an observatory for his son in the garden of the family home. It is from here that Wolf was credited with his first astronomical discovery, comet 14P/Wolf, in 1884. Life at the university Wolf attended his local university and, in 1888, at the age of 25, was awarded a Ph.D. by the University of Heidelberg. He spent one year of post-graduate study in Stockholm, the only significant time he would spend outside of Heidelberg in his life. He returned to the University of Heidelberg and accepted the position of ''pri ...

UH88
The University of Hawai'i 88-inch (2.24-meter) telescope—called UH88, UH2.2, or simply 88 by members of the local astronomical community—is situated at the Mauna Kea Observatories and operated by the University's Institute for Astronomy. It was constructed in 1968, and entered service in 1970, at which point it was known as "The Mauna Kea Observatory". It became one of the first professional telescopes to be controlled by a computer. The telescope was built with funding from NASA, to support Solar System missions, and is controlled by the University of Hawai'i. The success of the telescope helped demonstrate the value of Mauna Kea for astronomical observations. On December 4, 1984 it became the first telescope to make optical closure phase measurements on an astronomical source using an aperture mask. UH88 is a Cassegrain reflector tube telescope with an f/10 focal ratio, supported by a large open fork equatorial mount. It was the last telescope on Mauna Kea to use a tube ...

Astronomical Objects Discovered In 1902
Astronomy () is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Babylonians, Greeks, Indians, Egyptians, Chinese, Maya, and many ancient indigenous peoples of the Americas. In the past, astronomy included disciplines as diverse as astrometry, celestial navigation, observational astronomy, and the making of calendars. Nowadays, professional a ...

American Astronomical Society
The American Astronomical Society (AAS, sometimes spoken as "double-A-S") is an American society of professional astronomers and other interested individuals, headquartered in Washington, DC. The primary objective of the AAS is to promote the advancement of astronomy and closely related branches of science, while the secondary purpose includes enhancing astronomy education and providing a political voice for its members through lobbying and grassroots activities. Its current mission is to enhance and share humanity's scientific understanding of the universe as a diverse and inclusive astronomical community. History The society was founded in 1899 through the efforts of George Ellery Hale. The constitution of the group was written by Hale, George Comstock, Edward Morley, Simon Newcomb and Edward Charles Pickering. These men, plus four others, were the first Executive Council of the society; Newcomb was the first president. The initial membership was 114. The AAS name of the so ...

P/2016 G1 (PanSTARRS)
P/2016 G1 (PanSTARRS) was a main-belt asteroid that was destroyed by an impact event on 6 March 2016. It was discovered by Robert Weryk and Richard Wainscoat of the Pan-STARRS 1 survey at Haleakala Observatory. The object was initially thought to be an Encke-type comet because of its diffuse appearance, so it received the periodic comet designation P/2016 G1. After further analysis, what had initially appeared to be a comet's halo turned out to be rubble from a collision. By November 2019, analysis suggested the collision had occurred on 6 March 2016, and the asteroid was struck by a smaller object that may have massed only , and was traveling at . P/2016 G1's diameter was between and . The asteroid had completely disintegrated by 2017. Astronomers were able to use the asteroid's rubble to determine the date of the collision, since the dispersion of dust was inversely proportional to its size.

Active Asteroid
Active asteroids are small Solar System bodies that have asteroid-like orbits but show comet-like visual characteristics. That is, they show comae, tails, or other visual evidence of mass-loss (like a comet), but their orbit remains within Jupiter's orbit (like an asteroid). These bodies were originally designated main-belt comets (MBCs) in 2006 by astronomers David Jewitt and Henry Hsieh, but this name implies they are necessarily icy in composition like a comet and that they only exist within the main-belt, whereas the growing population of active asteroids shows that this is not always the case. The first active asteroid discovered is 7968 Elst–Pizarro. It was discovered (as an asteroid) in 1979 but then was found to have a tail by Eric Elst and Guido Pizarro in 1996 and given the cometary designation 133P/Elst-Pizarro. Orbits Unlike comets, which spend most of their orbit at Jupiter-like or greater distances from the Sun, active asteroids follow orbits within the orb ...

Magellan Telescopes
The Magellan Telescopes are a pair of optical telescopes located at Las Campanas Observatory in Chile. The two telescopes are named after the astronomer Walter Baade and the philanthropist Landon T. Clay. First light for the telescopes was on September 15, 2000 for the Baade, and September 7, 2002 for the Clay. A consortium consisting of the Carnegie Institution for Science, University of Arizona, Harvard University, the University of Michigan and the Massachusetts Institute of Technology built and operate the twin telescopes. The telescopes were named after the sixteenth-century Portuguese explorer Ferdinand Magellan. The Giant Magellan Telescope (GMT) is an extremely large telescope under construction, as part of the US Extremely Large Telescope Program. Current instruments on the Magellan Telescopes Baade telescope: * Inamori Magellan Areal Camera and Spectrograph (IMACS) * FourStar * Folded port InfraRed Echellette (FIRE) * Magellan Echellete (MagE) Clay telescope: * Mag ...
