The Veil Nebula is about 2,100 light-years from Earth in the constellation of Cygnus (the Swan), making it a relatively close neighbor in astronomical terms. It’s the visible portion of a supernova remnant formed around 10,000 years ago known as the Cygnus Loop.
This image which only shows a portion of the nebula. It was assembled from data taken using five different filters with the Wide Field Camera 3 on the Hubble Space Telescope. Post-processing of the data brings out enhanced details of emissions from doubly ionized oxygen (blues) and ionized hydrogen and ionized nitrogen (reds).
The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus. It’s the visible portions of the Cygnus Loop, a large but relatively faint supernova remnant. The source supernova exploded between 5,000 to 8,000 years ago, and the remnants have since expanded to cover a swath of the sky roughly 3 degrees across, about 6 times the diameter of the Full Moon.
This 3-D visualization flies across a small part of the Veil Nebula. It was created using data from the Hubble Space Telescope. It covers part of a the expanding remnant from a star that exploded thousands of years ago, highlighting the emissions from different chemical elements in different layers of gas within the nebula. Emissions from hydrogen, sulfur, and oxygen are shown in red, green, and blue, respectively.
