The NASA/ESA Hubble Space Telescope has reposted its image of the Veil Nebula that originally appeared in 2015. This time, due to the new processing technology, more details can be seen.
As Digital trend According to reports, this photo depicts the Veil Nebula, a fragment of what NASA describes as one of the most famous supernova remnants. It is estimated that the start time of the supernova explosion is 20 times that of the earth and the sun. Its name derives from the “exquisite, draped filamentous structure”. The entire nebula spans 110 light years, and when viewed from the earth, it will cover six full moons in the sky. It is located in the constellation Cygnus about 2100 light years away.
“The ancestor star of the Veil Nebula is 20 times the mass of the sun. It lived very fast, died young, and ended its life with a catastrophic release of energy.” Despite such a violent incident, supernovae were produced. The shock waves and debris carved out the delicate traces of ionized gas in the Veil Nebula, creating surprising astronomical beauty. “The European Space Agency (ESA) said.
This photo is a mosaic of six photos taken by Hubble in a small area (about two light years) of the nebula, so it covers only a small part of the entire structure of the nebula. The original pictures uploaded in 2015 are as follows:
Although it works well, its resolution is much lower than that of the new technology, and the colors and details of the nebula structure are still rarely defined. You can see below:
“Astronomer William Herschel discovered the Veil Nebula in 1784. William Fleming discovered the darker part of the nebula in 1904, called the Pickering Triangle (in Fleming worked after the director of the Harvard Observatory), which is what his work follows,” ESA wrote. “It’s best to watch the Veil Nebula in the early autumn of the northern hemisphere (early spring in the southern hemisphere). It is about level 8. The nebula cannot be seen with the naked eye, but you can see it under a dark sky through a telescope or even binoculars. To brighten the appearance of the veil and eliminate its sparse features.”

ESA wrote: “In order to produce color images, Hubble’s wide-angle camera 3 instrument used five different filters for observation.” “The new post-processing method further enhances dual ionized oxygen, ionized hydrogen and Ionized nitrogen emissions details.”
In the figure above, ionized oxygen is shown in blue, while ionized hydrogen and nitrogen are shown in red.
The Veil Nebula has also recently been included as part of Hubble’s Caldwell Catalog, which is a collection of astronomical objects photographed by Hubble that can be seen by amateur astronomers in the night sky.
