A spectacular return to the Veil Nebula

This week’s photo revisits the Veil Nebula, a popular subject of Hubble images!This object was introduced in Previous Hubble Photo ReleaseBut now, new processing techniques are being applied to bring out the details of the delicate threads of the nebula and the filaments of the ionizing gas.

Observations taken through Hubble’s three wide-field cameras through five different filters were used to create this colorful image. The new post-treatment method further enhances the details of emissions from double-ionized oxygen (shown here in blue), ionized hydrogen, and ionized nitrogen (shown here in red).

The Veil Nebula is located in Cygnus (Swan), about 2100 light-years away from Earth, and is astronomically close to it. In this image, only a small part of the nebula is taken.

The Veil Nebula is the visible part of the nearby Cygnus loop. This is a supernova remnant formed by the death of a giant star about 10,000 years ago. The ancestral stars of the Veil Nebula, which weighed 20 times the mass of the Sun, lived fast, died young, and ended their lives with catastrophic energy releases. Despite this stellar violence, shock waves and debris from supernovae formed a delicate mesh pattern of ionized gas in the Veil Nebula — creating a scene of amazing astronomical beauty.
