Amazing Space Glossary of Astronomy Terms - Part 2 of 4 (NASA)|
Disk: A pancake-shaped structure composed primarily of young and middle-aged stars, and having abundant gas and dust. Some old stars are also present. The disk surrounds the bulge in a spiral galaxy. The disk in the
Milky Way is 100,000 light-years across and 12,000 light-years thick.
Edge-on Spiral Galaxy: A spiral galaxy viewed from the side so that the disk containing the spiral arms appears to be a thin line of stars and dust crossing and extending beyond the bulge. Stars in the halo also may be visible. The spiral arm structure is not visible when a spiral galaxy is viewed 'edge-on.'
Elliptical Galaxy: A galaxy having an elliptical shape. Some elliptical galaxies are nearly spherical, while others are more oblate, resembling footballs. An elliptical galaxy is essentially a big bulge composed mostly of old stars and containing little interstellar matter (the gas and dust often found in the space between stars).
ESO: These letters, when followed by numbers, refer to the specific entries in an archive of observations made by the European Southern Observatory telescopes. Since the Hubble Space Telescope (HST) is a joint venture between NASA and the European Space Agency, ESO numbers are used to designate HST discoveries. Galaxies with ESO numbers are generally not included in earlier catalogs, such as those with numbers starting with “NGC” (designating John Dreyer’s New General Catalogue of Nebulae and Clusters of Stars) or “M” (designating Charles Messier’s Catalog of Nebulae and Star Clusters).
Face-on Spiral Galaxy: A spiral galaxy viewed from above so that the spiral arm structure is visible.
