170 4. THE EXTRAGALACTIC ATLAS 4.3.2 Constellations Group Name constel Reference — Prepared by Brian Abbott, Carter Emmart (AMNH/<strong>Hayden</strong>) Labels Yes Files constellations.speck, constellations.label Dependencies none Census 88 constellations and labels In the Extragalactic Atlas, we provide the constellation lines along with the stars for night-sky context. They, too, are fixed on the 1 Mpc sphere and have a single color (unlike the Milky Way Atlas). For a full description of these lines and their meaning, please refer to “Constellation Connectivity Lines” in the Milky Way Atlas.
4.3. EXTRAGALACTIC DATA GROUPS 171 4.3.3 Visible All-Sky Survey Group Name mwVis Reference Axel Mellinger (Universitaet Potsdam) Prepared by Ryan Wyatt (AMNH/<strong>Hayden</strong>) Labels No Files mw-visible.speck Dependencies mellinger-optmw.sgi Wavelength 400 nm − 700 nm Frequency 750,000 GHz − 430,000 GHz The visible Milky Way shows the Milky Way Galaxy from Earth’s perspective, our night-sky view. This all-sky image shows the gas and dust visible to us from our own Galaxy. Because we cover this image in greater detail in the Milky Way Atlas, we will forgo discussing it here. Instead, we will refer you to “Visible All-Sky Survey” for a thorough description of the image. Like the objects in the Milky Way Atlas, the all-sky images in the Extragalactic Atlas are placed at a fixed distance. Of course, the Extragalactic Atlas’s megaparsec scale is much larger than that of the Milky Way Atlas’s parsec scale. You may recall in the Milky Way Atlas that the visible all-sky image is placed at an arbitrary distance of 1,000 parsecs (or 3,260 light-years). In the Extragalactic Atlas, we place the all-sky image on a sphere with a radius of 1 Mpc, or 3.26 million light-years. This distance corresponds with that of the stars group, constel group, and the coordinate spheres.
