Vera Rubin

Vera Florence Cooper Rubin (/ˈruːbɪn/; July 23, 1928 – December 25, 2016) was an American astronomer who pioneered work on galaxy rotation rates.[1] She uncovered the discrepancy between the predicted angular motion of galaxies and the observed motion, by studying galactic rotation curves. This phenomenon became known as the galaxy rotation problem, and was evidence of the existence of dark matter.[2] Although initially met with skepticism, Rubin's results were confirmed over subsequent decades. Her legacy was described by The New York Times as "ushering in a Copernican-scale change" in cosmological theory.[1][3]

NED - NASA/IPAC Extragalactic Database

Image
The NASA/IPAC Extragalactic Database ( NED ) is an on-line astronomical database for astronomers that collates and cross-correlates astronomical information on extragalactic objects (galaxies, quasars, radio, x-ray and infrared sources, etc.). NED was created in the late 1980s by two Pasadena astronomers, George Helou and Barry F. Madore. NED is funded by NASA and is operated by the Infrared Processing and Analysis Center (IPAC) on the campus of the California Institute of Technology , under contract with NASA . NED is built around a master list of extragalactic objects for which cross-identifications of names have been established, accurate positions and redshifts entered to the extent possible, and some basic data collected. Bibliographic references relevant to individual objects have been compiled, and abstracts of extragalactic interest are kept on line. Detailed and referenced photometry, position, and redshift data, have been taken from large compilations and from

Schiaparelli (SkiAppUhRelEE)

Image
Schiaparelli EDM lander [skjapaˈɾɛlːi] was the Entry, Descent and Landing Demonstrator Module (EDM) of the ExoMars programme—a joint mission of the European Space Agency (ESA) and the Russian space agency Roscosmos . [4] It was built in Italy and was intended to test technology for future soft landings on the surface of Mars . [5] It also had a limited but focused science payload that would have measured atmospheric electricity on Mars and local meteorological conditions.
