She was professor emerita of astronomy at Swarthmore College and director emerita of the college's Sproul Observatory. She was a pioneer in the use of astrometry to determine the character of binary stars and search for extrasolar planets. Education Lippincott received a Bachelor of Arts degree from the University of Pennsylvania in 1941 and an Master of Arts from Swarthmore College in 1942. Life Lippincott was born in 1920 and attended college at the University of Pennsylvania College for Women in the 1940s, where she played on the women's basketball team. After graduation from the University of Pennsylvania, Lippincott attended Swarthmore College, where she worked closely with Peter van de Kamp on many astrometry projects between 1945 and his retirement in 1972, when she became observatory director. She wrote his obituary when he died in 1 ...

Philadelphia, Pennsylvania
Philadelphia, often called Philly, is the largest city in the Commonwealth of Pennsylvania, the sixth-largest city in the U.S., the second-largest city in both the Northeast megalopolis and Mid-Atlantic regions after New York City. Since 1854, the city has been coextensive with Philadelphia County, the most populous county in Pennsylvania and the urban core of the Delaware Valley, the nation's seventh-largest and one of world's largest metropolitan regions, with 6.245 million residents . The city's population at the 2020 census was 1,603,797, and over 56 million people live within of Philadelphia. Philadelphia was founded in 1682 by William Penn, an English Quaker. The city served as capital of the Pennsylvania Colony during the British colonial era and went on to play a historic and vital role as the central meeting place for the nation's founding fathers whose plans and actions in Philadelphia ultimately inspired the American Revolution and the nation's inde ...

Today (NBC Program)
''Today'' (also called ''The Today Show'' or informally, ''NBC News Today'') is an American news and talk morning television show that airs weekdays from 7:00 a.m. to 11:00 a.m. on NBC. The program debuted on January 14, 1952. It was the first of its genre on American television and in the world, and after 70 years of broadcasting it is fifth on the list of longest-running United States television series. Originally a weekday two-hour program from 7:00 a.m. to 9:00 a.m., it expanded to Sundays in 1987 and Saturdays in 1992. The weekday broadcast expanded to three hours in 2000, and to four hours in 2007 (though over time, the third and fourth hours became distinct entities). ''Today''s dominance was virtually unchallenged by the other networks until the late 1980s, when it was overtaken by ABC's ''Good Morning America''. ''Today'' retook the Nielsen ratings lead the week of December 11, 1995, and held onto that position for 852 consecutive weeks until the ...

Honorary Degree
An honorary degree is an academic degree for which a university (or other degree-awarding institution) has waived all of the usual requirements. It is also known by the Latin phrases ''honoris causa'' ("for the sake of the honour") or ''ad honorem '' ("to the honour"). The degree is typically a doctorate or, less commonly, a master's degree, and may be awarded to someone who has no prior connection with the academic institution or no previous postsecondary education. An example of identifying a recipient of this award is as follows: Doctorate in Business Administration (''Hon. Causa''). The degree is often conferred as a way of honouring a distinguished visitor's contributions to a specific field or to society in general. It is sometimes recommended that such degrees be listed in one's curriculum vitae (CV) as an award, and not in the education section. With regard to the use of this honorific, the policies of institutions of higher education generally ask that recipients ...

Kappa Kappa Gamma
Kappa Kappa Gamma (), also known simply as Kappa or KKG, is a collegiate sorority founded at Monmouth College in Monmouth, Illinois, United States. It has a membership of more than 260,000 women, with 140 collegiate chapters in the United States and Canada and 307 alumnae associations worldwide. The main archive URL iThe Baird's Manual Online Archive homepage It is sometimes referred to by its original designation, a "women's fraternity", as it was founded before the term "sorority" was coined. It is a founding member of the National Panhellenic Conference (NPC), an umbrella organization that includes 26 American sororities. History In 1869, two Monmouth College students, Mary Louise Bennett and Hannah Jeannette Boyd, were dissatisfied with the fact that, while men enjoyed membership in fraternities, women had few equivalent organizations for companionship, support, and advancement, and were instead limited to literary societies. Bennett and Boyd decided to create a women's frate ...

Hale Telescope
The Hale Telescope is a , 3.3 reflecting telescope at the Palomar Observatory in San Diego County, California, US, named after astronomer George Ellery Hale. With funding from the Rockefeller Foundation in 1928, he orchestrated the planning, design, and construction of the observatory, but with the project ending up taking 20 years he did not live to see its commissioning. The Hale was groundbreaking for its time, with double the diameter of the second-largest telescope, and pioneered many new technologies in telescope mount design and in the design and fabrication of its large aluminum coated "honeycomb" low thermal expansion Pyrex mirror. It was completed in 1949 and is still in active use. The Hale Telescope represented the technological limit in building large optical telescopes for over 30 years. It was the largest telescope in the world from its construction in 1949 until the Soviet BTA-6 was built in 1976, and the second largest until the construction of the Keck Observ ...

Walter Baade
Wilhelm Heinrich Walter Baade (March 24, 1893 – June 25, 1960) was a German astronomer who worked in the United States from 1931 to 1959. Biography The son of a teacher, Baade finished school in 1912. He then studied maths, physics and astronomy at the universities of Münster and Göttingen. After receiving his PhD in 1919, Baade worked at Hamburg Observatory at Bergedorf from 1919 to 1931. There in 1920 he discovered 944 Hidalgo, the first of a class of minor planets now called Centaurs which cross the orbits of giant planets. He worked at Mount Wilson Observatory from 1931 to 1958. There, during World War II, he took advantage of wartime blackout conditions (which reduced light pollution), to resolve stars in the center of the Andromeda Galaxy for the first time. These observations led him to define distinct "populations" for stars (Population I and Population II). The same observations led him to discover that there are two types of Cepheid variable stars. Using this disc ...

Ross 614
Ross 614 (V577 Monocerotis) is a red dwarf UV Ceti flare star and it is the primary member of a nearby binary star system in the constellation of Monoceros. This star has a magnitude of about 11, making it invisible to the unaided eye even though it is one of the stars nearest to the Sun. This system is among the closest to the Sun at an estimated distance of about 13.3 light years. Because this star is so close to the Earth it is often the subject of study, hence the large number of designations by which it is known. Binary star system This binary star system consists of two closely spaced low-mass red dwarfs. The secondary star is a dim magnitude 14 lost in the glare of the nearby primary star. A study by George Gatewood in 2003 using older sources along with data from the Hipparcos satellite yielded an orbital period of about 16.6 years and a semi-major axis separation of about 1.1 arc seconds (2.4–5.3 AU). The most recent determination of the system orbital ...

Binary Star
A binary star is a system of two stars that are gravitationally bound to and in orbit around each other. Binary stars in the night sky that are seen as a single object to the naked eye are often resolved using a telescope as separate stars, in which case they are called ''visual binaries''. Many visual binaries have long orbital periods of several centuries or millennia and therefore have orbits which are uncertain or poorly known. They may also be detected by indirect techniques, such as spectroscopy (''spectroscopic binaries'') or astrometry (''astrometric binaries''). If a binary star happens to orbit in a plane along our line of sight, its components will eclipse and transit each other; these pairs are called ''eclipsing binaries'', or, together with other binaries that change brightness as they orbit, ''photometric binaries''. If components in binary star systems are close enough they can gravitationally distort their mutual outer stellar atmospheres. In some cases, thes ...

The Astronomical Journal
''The Astronomical Journal'' (often abbreviated ''AJ'' in scientific papers and references) is a peer-reviewed monthly scientific journal owned by the American Astronomical Society (AAS) and currently published by IOP Publishing. It is one of the premier journals for astronomy in the world. Until 2008, the journal was published by the University of Chicago Press on behalf of the AAS. The reasons for the change to the IOP were given by the society as the desire of the University of Chicago Press to revise its financial arrangement and their plans to change from the particular software that had been developed in-house. The other two publications of the society, the ''Astrophysical Journal'' and its supplement series, followed in January 2009. The journal was established in 1849 by Benjamin A. Gould. It ceased publication in 1861 due to the American Civil War, but resumed in 1885. Between 1909 and 1941 the journal was edited in Albany, New York. In 1941, editor Benjamin Boss arrange ...
