Two Trillion Galaxies and counting

The universe seems a little less lonely today. Astronomers from the University of Nottingham conducted a new survey of the universe’s galaxy population and concluded that previous estimates lowballed the census by a factor of about 20. Using data from Hubble and telescopes around the world, as well as a new mathematical model, they estimate that there are ten times more galaxies in the observable universe than we thought; previous estimates put the number of galaxies in the universe at around 200 billion.

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.
