The Veil Nebula is 2100 light-years away from Earth in the constellation Cygnus. It was the subject of the Hubble image release in 2015, but the new look highlights what the European Space Agency (ESA) described in a statement this week as “nebula fine lines and filaments of ionized gas.”
At first glance, the changes between the two versions of the images seem to be small, but the difference lies in the details. “The new post-treatment method further enhances the emission details of dual ionized oxygen (shown here in blue), ionized hydrogen and ionized nitrogen (shown here in red),” ESA said.
ESA and NASA jointly operate the Hubble Space Telescope. NASA also shared the new look of the Veil Nebula on Friday.
The Hubble image shows only part of an interesting space region. The Veil Nebula is a supernova remnant formed by the “death” of a huge star about 10,000 years ago. The shock waves and debris generated by the supernova shape the fine traces of ionized gas in the Veil Nebula, creating an astonishing astronomical beauty.
