WorldWide Telescope (WWT) is an open-source set of applications, data and cloud services, [4][5] originally created by Microsoft Research but now an open source project hosted on GitHub. [6] The .NET Foundation holds the copyright and the project is managed by the American Astronomical Society and has been supported by grants from the Moore ...
The Centre de Données astronomiques de Strasbourg ( CDS; English translation: Strasbourg Astronomical Data Centre) is a data centre which collects and distributes astronomical information [1] . It was established in 1972 under the name Centre de Données Stellaires by the National Institute of Astronomy and Geophysics (INAG).
The Messier objects are a set of 110 astronomical objects catalogued by the French astronomer Charles Messier in his Catalogue des Nébuleuses et des Amas d'Étoiles (Catalogue of Nebulae and Star Clusters). Because Messier was interested only in finding comets, he created a list of those non-comet objects that frustrated his hunt for them.
Lists of astronomical objects. Selection of astronomical bodies and objects: Moon Mimas and Ida, an asteroid with its own moon, Dactyl. Comet Lovejoy and Jupiter, a giant gas planet. The Sun; Sirius A with Sirius B, a white dwarf; the Crab Nebula, a remnant supernova. A black hole (artist concept); Vela Pulsar, a rotating neutron star.
The interstellar dust in M110 has a mass of (1.1–1.8) × 10 4 M ☉ with a temperature of 18–22 K, and the interstellar gas has (4–7) × 10 6 M ☉. The inner region has sweeping deficiencies in its interstellar medium IM, most likely expelled by supernova explosions.
Celestia is a real-time 3D astronomy software program that was created in 2001 by Chris Laurel. The program allows users to virtually travel through the universe and explore celestial objects that have been catalogued. Celestia also doubles as a planetarium, but the user is not restricted to the Earth's surface, like in other planetarium ...
Astronomical object. An astronomical object, celestial object, stellar object or heavenly body is a naturally occurring physical entity, association, or structure that exists within the observable universe. [1] In astronomy, the terms object and body are often used interchangeably. However, an astronomical body or celestial body is a single ...
The NASA/IPAC Extragalactic Database (NED) is an online 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.
