![]() ![]() The Western Veil (also known as Caldwell 34), consisting of NGC 6960 (the "Witch's Broom", Lacework Nebula, "Filamentary Nebula" ) near the foreground star 52 Cygni.The structure is so large that several NGC numbers were assigned to various arcs of the nebula. In modern usage, the names Veil Nebula, Cirrus Nebula, and Filamentary Nebula generally refer to all the visible structure of the remnant, or even to the entire loop itself. (25 November 2012) George Willis Ritchey image of what he called the Great Nebula in Cygnus (In modern times the Veil Nebula) taken with the two-foot reflecting telescope with 3 hours exposure at the Yerkes Observatory in 1901. Components NASA photograph of the Cygnus Loop in ultraviolet light, with labels to well known features. On 24 September 2015 new images and videos of the Veil Nebula were released by the Space Telescope Science Institute, with an explanation of the images. The Cygnus Loop is also a strong emitter of radio waves and x-rays. The analysis of the emissions from the nebula indicates the presence of oxygen, sulfur, and hydrogen. The Hubble Space Telescope captured several images of the nebula. (The distance estimates affect also the estimates of size and age.) While previous distance estimates have ranged from 1200 to 5800 light-years, a recent determination of 2400 light-years is based on direct astrometric measurements. The remnants have since expanded to cover an area of the sky roughly 3 degrees in diameter (about 6 times the diameter, and 36 times the area, of the full Moon). At the time of the explosion, the supernova would have appeared brighter than Venus in the sky, and visible in the daytime. ![]() The source supernova was a star 20 times more massive than the Sun which exploded between 10,000 and 20,000 years ago. It constitutes the visible portions of the Cygnus Loop, a supernova remnant, many portions of which have acquired their own individual names and catalogue identifiers. The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus. Besides tasty food, Halloween tableware elevates a gathering to the next level.NGC 6960, 6992, 6995, 6974, and 6979, IC 1340, Cygnus Loop, Cirrus Nebula, Filamentary Nebula, Witch's Broom Nebula (NGC 6960), Caldwell 33/34Ī false-colour narrowband image made using amateur equipment If you’re looking to dress up your spooky snacks even more, we’ve even included a few serveware items such as glass beakers and pumpkin-shaped bowls for an extra pop of seasonal spirit.
