The analysis of its emissions indicate that it contains oxygen, hydrogen, and sulphur. The entire structure spans about 3 degrees, corresponding to about 6 full moons.
However, an observer can see the nebula clearly in a telescope using an OIII filter a filter isolating the wavelength of light from doubly ionized oxygenas almost all light from this nebula is emitted at this wavelength. Over time, the energy and material that was ejected into the interstellar medium has slowly expanded, and now the nebula covers an area of sky over seven times the diameter of the full Moon.
At an estimated distance of 1, light-years from us, at the time of the explosion the supernova would have been bright enough to cast strong shadows on Earth.
The Veil Nebula has three main parts: This image from the Digital Sky Survey shows a 3o x 3o region about the nebula. Some argue that it can be seen without any optical aid except an OIII filter held up to the eye.
John Herschel assigned the nebula two different numbers inwhile Truman Safford discovered and catalogued IC in Gienah is one of the stars of the Northern Cross and marks the right wing of the celestial Swan.
Even though the nebula has a relatively bright integrated magnitude of 7, it is spread over so large an area that the surface brightness is quite low, so the nebula is notorious among astronomers as being difficult to see. It formed from the violent death of a star twenty times the mass of the Sun that exploded about years ago.
When a star significantly heavier than our Sun runs out of fuel, it collapses and blows itself apart in a catastrophic supernova explosion. The red colour arises after gas is swept into the shock wave — which is moving at almost 1.

It spans a region of about 35 light years. The Western Veil Nebula, NGCis the easiest component to find as it lies behind the star 52 Cygni, which is bright enough to be seen without binoculars.
The Cygnus Loop has a radio source designation W78 and is also known as Sharpless Fascinating smoke-like wisps of gas are all that remain visible of what was once a Milky Way star.
For amateur astronomers, the nebula makes one of the most spectacular objects in the northern sky. The X-ray source Cygnus X-5 coincides with the supernova remnant. These shocks, driven by debris moving atkilometres per hour, heat the gas to millions of degrees.
The Veil Nebula is a frequent object of study for astronomers because it is large, located relatively close to Earth, and makes a good example of a middle-aged supernova remnant.Information about the Veil Nebula, an interesting supernova remnant in Cygnus.
Finder map and picture. The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus. It constitutes the visible portions of the Cygnus Loop, a supernova remnant, many portions of which have acquired their own. The Veil Nebula is a diffuse nebula located in the northern constellation Cygnus, the Swan.
Also known as Witch's Broom Nebula, Bridal Veil Nebula, Cirrus. The Bridal Veil nebula is a large and complex, spanning over 3 killarney10mile.com expelled remnants of a long ago supernova, it can be seen strewn all about the region on long exposure photos, but it is the two brightest parts that are typically seen visually.
Nov 21, · Page 1 of 2 - Seeing the Veil Nebula - posted in Deep Sky Observing: Hi, since I first got into astronomy, one of the objects I really wanted to see was the Veil Nebula in Cygnus.
At the time I first started, I had only my 70mm refractor, the starter eyepieces, and some charts printed off Starry Night program. I remember looking for. The gorgeous, multicolored remnants of a destroyed star shimmer in stunning new images by the Hubble Space Telecope. The new set of Hubble photos of the Veil Nebula, which researchers combined.Download
