A supernova remnant (SNR) is the structure remaining after a star explodes as a supernova. It consists of ejected stellar material and an expanding shock wave that sweeps up and heats surrounding interstellar gas.

📸 Veil Nebula: Wisps of an Ancient Supernova
About 7,000 years ago, a star exploded in the Milky Way, creating the Veil Nebula. Once as bright as a crescent Moon, it now appears as delicate filaments of gas in the constellation Cygnus. This image from Kuwait in 2024 shows hydrogen in red and oxygen in blue.

An article published in "The Astronomical Journal" reports evidence that the supernova remnant cataloged as 30 Doradus B, or simply 30 Dor B, is the result of at least two separate supernovae and not just one.

In this new #JWST NIRCam image of the supernova remnant Cassiopeia A (Cas A), we see the remains of a star that first imploded and then exploded about 340 years ago (from our point of view), leaving behind a tangle of gas, dust, and magnetic fields.

A #thread with some details of what we are seeing in the image.

How did we deserve this?!? A Sunday nite (EST) / Monday wee hours (CET) spectacular #Webb image drop at 1:00 UTC, a NIRCam image of the #SuperNovaRemnant #CasA from 1.6 to 4.4 µm wavelength: https://esawebb.org/news/weic2330/ or https://webbtelescope.org/contents/news-releases/2023/news-2023-149 or https://www.nasa.gov/missions/webb/nasas-webb-stuns-with-new-high-definition-look-at-exploded-star/

From an amateur PN candidate to the Rosetta Stone of SN Iax research: https://arxiv.org/abs/2311.03700 -> Pa 30 and its central star IRAS 00500+6713 are now "the only SN Iax remnant in our Galaxy, the only known bound remnant of any SN, and based on the central star's spectrum the only Wolf-Rayet star known that neither has a massive progenitor nor is the central star of a Planetary Nebula." #SuperNovaRemnant

As seen by #Webb from 1.6 to 21 µm (NIRCam and MIRI) the #CrabNebula #SuperNovaRemnant doesn't look too different from the view in visible light: https://webbtelescope.org/contents/news-releases/2023/news-2023-137 and https://esawebb.org/images/weic2326a/ and https://www.nasa.gov/missions/webb/the-crab-nebula-seen-in-new-light-by-nasas-webb/ and https://www.esa.int/Science_Exploration/Space_Science/Webb/Webb_sees_Crab_Nebula_in_new_light

Check out this new #JWST image of the Crab Nebula 🤩

The milky smoke-like glow in the nebula's center comes from synchrotron radiation, light produced by charged particles, like electrons, moving around magnetic fields at relativistic speeds.

Curvy wisps outline the structure of the pulsar’s magnetic field, which sculpts and shapes the nebula. A faint ring of white material encircles the pulsar, a tiny white dot, at the very center.

I was finally able to get enough data to consider this completed. The Crescent Nebula and surrounding nebulosity. I ended up with about 15 hours of narrowband data with a ALP-T dual narrowband filter, then I added about 1 hour of broadband data for the stars.

Cygnus Loop

Around 725pc (2400ly) distant, the Cygnus Loop (Sharpless Sh2-103) is an emission nebula in Cygnus nearly 3° across, a large supernova remnant caused by a star 12-15 solar masses (unidentified).
