Today Chandra is studying E0102, a supernova remnant produced by the explosion of a massive star in a nearby galaxy. Most of the oxygen in the Universe is synthesized in massive stars. The amount of oxygen in this ring alone is enough for thousands of solar systems.

this supernova remnant was created when a massive star exploded 10,000 years ago

it still glows because of the heat generated by collision with the surrounding interstellar gas - but why the nebula also glows in X-ray light is a mystery. one possibility is the energetic pulsar co-created with the remnant, powering the nebula with a wind expelled at 1000 kilometers per second

Photo of Pickering's triangle (also known as Fleming's triangle) and NGC 6979 / NGC 6974 (the more diffused clouds at the top center/left). This is the third part of the Cygnus loop / veil nebula, this part of the supernova remnant is fainter than the previous two parts of the loop I photographed. This explains in part why it was only discovered by in 1904 by Williamina Fleming (whereas the two writer part were discovered in 1784 by William Herschel). Williamina Fleming was a pioneer in stellar classification, she worked with other women at the Harvard college observatory. Their work in star classification resulted in the Henry Draper Catalogue, an extensive (225 300 stars in the first edition) classification of stars with their position and their spectra. Williamina is also credited with the discovery of 59 nebula (including the famous hors head nebula) more than 300 variable stars as well as (with Henry Norris Russell and Edward Charles Pickering) the discovery of white dwarfs (the remnants of dead sun-like stars).

Rampaging Fronts of the Veil Nebula - March 7th, 1996.

"A supernova explosion of a high-mass star results in fast moving blast waves. At the front of the waves shown above, ionised gas in the Veil Supernova Remnant rushes out from the explosion, sweeps up material, and breaks up many atoms into constituent ions and electrons. Observations with the Hubble Space Telescope in 1993 indicate that the blue shock wave was catapulted away from the stellar explosion after the red shock wave, and had yet to catch up to it in some regions. The Veil supernova remnant's has a very large angular size - six times the diameter of the full Moon - and different parts of it are known as the "Cygnus Loop" and catalog numbers NGC 6960, NGC 6979, NGC 6992, and NGC 6995."

The Eastern Veil Nebula (OHS, starless)

The Veil Nebula is a 15,000 year old supernova remnant in the Cygnus constellation, which is loaded with heavily ionized gas due to the high energies emitted during its parent supernova and spread out in swirling tendrils from the force of the blast. The full Veil Complex is vast, but zooming in on the target reveals incredible levels of detail like this.

This shot is a tight zoom on the end of the Eastern Veil Nebula, shot at 1600mm with a 200mm Ritchey-Chretien telescope and an ASI533MM camera. 8h 30m of total integration time across Ha, Sii, and Oiii narrowband filters (7nm bandpass). Data gathered over two nights.

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).
