The subject of this NASA/ESA Hubble Space Telescope Picture of the Week is the spiral galaxy NGC 337, located about 60 million light-years away in the constellation Cetus (The Whale).
This image combines observations made at two wavelengths, highlighting the galaxy’s golden centre and blue outskirts. The golden central glow comes from older stars, while the sparkling blue edges get their colour from young stars. If Hubble had observed NGC 337 about a decade ago, the telescope would have spotted something remarkable among the hot blue stars along the galaxy’s edge: a brilliant supernova.
The supernova, named SN 2014cx, is remarkable for having been discovered nearly simultaneously in two vastly different ways: by a prolific supernova hunter, Koichi Itagaki, and by the All Sky Automated Survey for SuperNovae (ASAS-SN). ASAS-SN is a worldwide network of robotic telescopes that scans the sky for sudden events like supernovae.
Researchers have determined that SN 2014cx was a Type IIP supernova. The “Type II” classification means that the exploding star was a supergiant at least eight times as massive as the Sun. The “P” stands for plateau, meaning that after the light from the supernova began to fade, the level reached a plateau, remaining at the same brightness for several weeks or months before fading further. This type of supernova occurs when a massive star can no longer produce enough energy in its core to stave off the crushing pressure of gravity. SN 2014cx’s progenitor star is estimated to have been ten times more massive than the Sun and hundreds of times as wide. Though it has long since dimmed from its initial brilliance, researchers are still keeping tabs on this exploded star, not least through the Hubble observing programme which produced this image.
[Image Description: A barred spiral galaxy on a dark background. The galaxy’s central region is a pale colour due to older stars, contains some pale reddish threads of dust, and is brighter along a broad horizontal bar through the very centre. Off the bar come several stubby spiral arms, merging into the outer region of the disc. It is a cool blue colour and contains some bright sparkling blue spots, both indicating young hot stars.]

A little later than most, but at last it's finished.
I've used Denys Schmidt Hope Valley, stippled it, and added a scrappy border from left-overs

M101 (181 exp). There is a supernova here - I'm just not sure where. I took a better picture of this galaxy - the pinwheel in Ursa Major - last year on a darker night

Seventeen years ago, astronomers witnessed supernova 2001ig go off 40 million light-years away in the galaxy NGC 7424, in the southern constellation Grus, the Crane. Shortly after, scientists photographed the supernova with the European Southern Observatory’s Very Large Telescope (VLT) in 2002. Two years later, they followed up with the Gemini South Observatory, which hinted at the presence of a surviving binary companion. As the supernova’s glow faded, scientists focused Hubble on that location in 2016. They pinpointed and photographed the surviving companion, which was possible only due to Hubble’s exquisite resolution and ultraviolet sensitivity. Hubble observations of SN 2001ig provide the best evidence yet that some supernovas originate in double-star systems.

Everybody loves it. Everybody drinks it. So good idea to get the dusty equipment out of the basement and give the old EOS M a good time and lets see what it can do.
For those whiskymaniacs out there: the Ardbeg Supernova was hard to get. When the shop opens the system got a breakdown and I tried for over an hour to get it. But thats most of the time when awesome bottles get released.

sollte eigentlich ein ganz normaler focusstack sein,
aber irgendwas ist da schiefgelaufen.
Aber egal, der Effekt ist genial !

This image of the supernova RCW 86 shows X-ray data from NASA's Chandra X-ray Observatory. Astronomers used these data to determine that a Type Ia supernova explosion, which was witnessed nearly 2,000 years ago by Chinese astronomers, was the source of the RCW 86 remnant seen today. Type Ia supernovas are created when an otherwise stable white dwarf is pushed beyond the brink of stability when a companion star dumps material onto it.

The light arriving from a supernova that occurred in M101, the Pinwheel Galaxy, was documented on May 19th 2023. This galaxy is around 21 million light years away.
I imaged this object on the 17th/18th before knowing any of this. When I learned this happen and say the images I planned on imaging it again. I had about 2 hours of clear skies on the morning of the 22nd and recaptured it.
I reprocessed the original frames, then used same steps on the new frames and created this movie.
A Type II supernova which exploded about 11,500 years ago and was about 800 light-years from earth

It seems like yesterday that the plants in this patch of sunflowers were mere seedlings. And now they're having seeds of their own!

Another doll to debox today. This back to back deboxing is fun, but quite stressful also. But, I'm almost there, only 4 more to go before I'm all caught up.
I was super excited when I saw Supernova's first photos. I love, love, love the old Colette sculpt and when I saw this one, I was thrilled. Not only was old Colette back, but she was gorgeous and different and awesome.
That skintone, the crimped hair, the pouty face--what's not to love? She has the presence of a goddess.
Deboxing her was a thrill. She is not only beautiful but comes with an accessory pack that does not seem to end--the choker, the hair ornament, numerous bangles, rings, earrings, shoes that are works of art, an awesome purse. I had worried that she would be too bright. Well, she is super bright and funky from head to toe, yet a joy to behold. She is what NuFace should be, pushing the limits.
February 24, 1987, will be remembered as one of the most spectacular events observed by astronomers in modern times. The destruction of a massive star in the Large Magellanic Cloud, a nearby galaxy, resulted in Supernova 1987A. This spawned detailed observations by many different telescopes, including NASA's Chandra X-ray Observatory and Hubble Space Telescope. The outburst was visible to the naked eye, and has been the brightest known supernova in almost 400 years.
This composite image from February 22, 2007, - 20 years after the supernova - shows the effects of a powerful shock wave moving away from the explosion. Bright spots of X-ray and optical emission arise where the shock collides with structures in the surrounding gas. These structures were carved out by the wind from the destroyed star. Hot-spots in the Hubble image (pink-white) now encircle Supernova 1987A like a necklace of incandescent diamonds. The Chandra data (blue-purple) reveals multimillion-degree gas at the location of the optical hot-spots. These data give valuable insight into the behavior of the doomed star in the years before it exploded.
