The Cygnus Loop - August 3rd, 1997.

"15,000 years ago, a star in the constellation of Cygnus exploded - the shockwave from this supernova explosion is still expanding into interstellar space! The collision of this fast moving wall of gas with a stationary cloud has heated it, causing it to glow in visible as well as high energy radiation, producing the nebula known as the Cygnus Loop (NGC 6960/95). The nebula is located about 2500 light-years away. The colours used here indicate emission from different kinds of atoms excited by the shock; oxygen-blue, sulfur-red, and hydrogen-green. This picture was taken with the Wide Field and Planetary Camera 2 onboard the Hubble Space Telescope."

The Cygnus Loop

[dum-enby-bi-boi]

Anyways this is the Cygnus loop :3

What you’re seeing are the beautiful remnants of a long dead star, estimated to have gone supernova some 20,000 years ago!

Thanks to NASA’s Chandra X-ray observatory you can access a viewable and (I think) 3D printable model of this nebula from the link \/

The Cygnus Loop (also known as the Veil Nebula) is a supernova remnant, the remains of the explosive death of a massive star.

The Western Veil Nebula

The Veil Nebula is interstellar debris from a very large star that violently exploded as a supernova about 15,000 years ago. This photo captures the leading shockwave as it continues to expand.

Astronomers call this Supernova Remnant the “Cygnus Loop”, because it is generally circular and viewed in the constellation of Cygnus the Swan. It is nearby at only 2,400 light years, and situated right in our own galactic spiral arm, making our image very crowded with nearby stars.

In this photo, we are looking at the outer edge of the Cygnus Loop debris field that appears facing towards the west. Note the colours: red is hydrogen, blue suggests oxygen, and sulfur is green.

A “Supernova” explosion occurs when an older star depletes fuel and begins to falter at generating a strong stellar wind. As the outward-push falters, gravity causes the aging star to catastrophically implode as a supernova. Indeed, the colours of blue and green suggest the presence of heavier elements, oxygen and sulphur, as formed in the core of older stars.

I photographed the Western Veil Nebula from my garden in Strasbourg France on a single night in August 2024. This is an ensemble of 80 photos, where each was a 3 minute exposure (4 hours of Astrophotography).

The Bat Nebula NGC 6995

The human brain just can't help itself, it's a bat right ? one that's 1,400 light years away, and 12 light years across and made from mostly hydrogen gas and dust, both reacting to UV light in emissions red, and in this filter, the blue is oxygen emissions.

The whole structure is part of a much larger area known as the Veil Nebula.

You can spot the bat on the left hand side, while the broom stick is across to the other side, of what looks like a spherical nebula.

In fact, the whole structure is a supernova remnant, and the edges bow shock waves still moving outwards.
