description Sharpless 2-103 Overview

Sharpless 2-103 is a section of the Cygnus Loop, a massive supernova remnant nearly 3 degrees across. The broader Cygnus Loop complex contains visible arcs of glowing gas, including the well-known Veil Nebula. This filamentary structure resulted from a massive star explosion roughly 8,000 years ago. The expanding shockwaves from this supernova continue to collide with interstellar gas, causing the debris to glow across visible and X-ray spectra.

help Sharpless 2-103 FAQ

What is the Sharpless 2-103 nebula?

Sharpless 2-103 is the formal catalog name for the famous Cygnus Loop. It is a massive supernova remnant located in the constellation Cygnus.

What caused the Sharpless 2-103 structure?

The structure was created by a colossal supernova explosion of a dying massive star. The remnant is an expanding cloud of debris still moving outward from the original blast site.

How large is Sharpless 2-103 in the night sky?

This supernova remnant spans nearly 3 degrees across the sky. This makes it roughly six times the width of the full moon as seen from Earth.

Is the Veil Nebula related to Sharpless 2-103?

Yes, the well-known Veil Nebula complex is actually made up of the visible arcs of Sharpless 2-103. The Filamentary, Witches Broom, and Pickering's Triangle are all glowing portions of this single massive structure.
