The veil nebula essay

At the time of the explosion, the supernova was likely as bright as a crescent Moon. The Hubble image was created from HST data from proposals and The chemical elements that constitute the Earth, the planets and animals we see around us - and as a matter of fact our very selves - were built deep inside ancient stars and in the supernova explosions that result in the nebula we are seeing here.

It is located at an approximate distance of 1, light years from Earth. The Cygnus Loop is a known source of soft X-rays.

How to observe the Veil Nebula?

This close-up look unveils wisps of gas, which are all that remain of what was once a star 20 times more massive than our sun.

The expanding shells of supernova remnants were mixed with other material in the Milky Way and became the raw material for new generations of stars and planets. The latter excited longer ago and have subsequently diffused into more chaotic structures.

The X-ray source Cygnus X-5 coincides with the supernova remnant.

Revisiting the Veil Nebula

It is the subsequent cooling of this material that produces the brilliantly coloured glows. Supernovae are extremely important for understanding our own Milky Way. 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.

Seeing the Veil Nebula

Though it was traditionally thought a difficult object to observe visually, the Veil Nebula is within the grasp of small telescopes. Some argue that it can be seen without any optical aid except an OIII filter held up to the eye. While not the brightest of the two large arcs, NGC runs directly through the wide 4th-magnitude double star 52 Cygni, making it the best place to start when studying the Veil.

The debris moves at aboutkilometres per hour and heats the surrounding gas to millions of degrees. Fascinating smoke-like wisps of gas are all that remain visible of what was once a Milky Way star. The nebula lies along the edge of a large bubble of low-density gas that was blown into space by the dying star prior to its self-detonation.

The Veil Nebula is a prototypical middle-aged supernova remnant, and is an ideal laboratory for studying the physics of supernova remnants: 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 blue coloured features — outlining the cavity wall — appear smooth and curved in comparison to the fluffy green and red coloured ones.

It is about 1, light-years away from Earth. This wind blew a large cavity into the surrounding interstellar gas. Undulations in the surface of the shell lead to multiple filamentary images, which appear to be intertwined. Like the larger scale ground-based observations, the high-resolution Hubble images display two characteristic features: A supernova releases so much light that it can outshine a whole galaxy of stars put together.

Now, overlaying WFPC2 images with new Wide Field Camera 3 WFC3 data provides even greater detail and allows scientists to study how far the nebula has expanded since it was photographed over 18 years ago.

The structure is so large that several NGC numbers were assigned to various arcs of the nebula. Some of the filamentary structure inside the arc can be clearly distinguished, but most of it is only seen well on long-exposure photographs. Owners of larger scopes may wish to try to see the illusive central portion of the nebula, which is found about part way between the two main halves.

These would have seen a star increase in brightness to roughly the brightness of the crescent Moon. It has the designation NGC in the New General Catalogue, which is sometimes used as an identifier for the entire nebula.

Located roughly light-years from Earth in the constellation of Cygnus The Swanthis brightly coloured cloud of glowing debris spans approximately light-years.Information about the Veil Nebula, an interesting supernova remnant in Cygnus.

Finder map and picture. Revisiting the Veil Nebula. 24 September The NASA/ESA Hubble Space Telescope imaged three magnificent sections of the Veil Nebula in Now, a stunning new set of images from Hubble’s Wide Field Camera 3 capture these scattered stellar remains in spectacular new detail and reveal its expansion over the last years.

The Western Veil Nebula is a supernova remnant in the constellation Cygnus. This astrophotography object is also known as the "witch's broom nebula". 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.

Veil Nebula

NASA's Hubble Space Telescope has unveiled in stunning detail a small section of the Veil Nebula - expanding remains of a massive star that exploded about 8, years ago. The Veil Nebula rides high in the northern summer sky on the wings of the beautiful constellation Cygnus the Swan.

Cygnus' brightest star, Deneb, along with Altair in Aquila and Vega in Lyra, form the well-known asterism of the Summer Triangle, which encloses a fabulous portion of the Milky Way.5/5(5).
