The Cygnus Loop
This is my SHO rendering of the Cygnus Loop.
Located within the constellation of Cygnus lies the remains of a once massive star. At the end of that star’s life, it exploded in what, today we call a supernova. An explosion so large that it ripped the star apart and expelled it’s remains far into space. As the shock wave from the supernova expands into the tenuous clouds of interstellar gas, it is heated and compressed. This causes the gas to glow.
Images of the Cygnus Loop Cleary show the interaction between the shock wave and the interstellar gas, allowing astronomers study and compare the theoretical model of such interactions, and actual event for the first time.
The Veil, and Cirrus nebulae are two of the better known components of the loop. However, there are several other structure with in the loop as well.
These include: NGC 6992, NGC 6995, and IC 1340:
These objects make up the Eastern Veil Nebula -- a large shell of interstellar hydrogen (H I), located along the north-eastern edge of the loop, with NGC 6992 being located RA 20h 56m 19.0s Dec +31° 44′ 34″. South of NGCC 6995 is another Shell of H I, NGC 6992, and even farther south is IC 1340 is located at RA 20h 56m 12.0s
Pickering's Triangle:
In 1904, Williamina Fleming, at Harvard Observatory, was examining photographic plates of the region when she discovered an area of nebulosity in the shape of a triangle. The brightest part of the triangle runs along the northern side, with nebulosity extending into the main area. The area was named Pickering’s Triangular, after where Edward Charles Pickering was director of the observatory at the time.
NGC 6974 and NGC 6979:
Located the northern edge of the loop, these objects are comprised of two brighter knots of nebulosity in a cloud to the east of the northern edge of Pickering's Triangle.
The data for this render was acquired via a robotic telescope within the “Telescope Live” network.
