M101 - The Dusty Pinwheel Galaxy and a Supernova! You can imagine my surprise back in May, when just a few days after getting started photographing this galaxy in my front garden, the news broke that a Supernova had just been discovered I was over the moon seeing the exploded star appear in the photos Needless to say, I thought this would be a great time to do a full project highlighting the Ha areas within the galaxy I must say, I had to resist stretching the data into overt artistic considerations given there appeared to be an ample amount of dust/tidal streams surrounding M101 I was tempted to see if there was any IFN nearby but held off given the potential to ruin the image with London's finest light pollution gradients no doubt lurking in the shadows (no pun intended!)
NASA details as follows:
About 170,000 light-years across, this galaxy is enormous, almost twice the size of our own Milky Way galaxy Its core is dominated by light from cool yellowish stars Along its grand design spiral arms are the blue colors of hotter, young stars mixed with obscuring dust lanes and pinkish star forming regions
A nearby star has exploded and humanity's telescopes are turning to monitor it The supernova, dubbed SN 2023ixf, was discovered by Japanese astronomer Koichi Itagaki three days ago and subsequently located on automated images from the Zwicky Transient Facility two days earlier SN 2023ixf occurred in the photogenic Pinwheel Galaxy M101, which, being only about 21 million light years away, makes it the closest supernova seen in the past five years, the second closest in the past 10 years, and the second supernova found in M101 in the past 15 years Rapid follow up observations already indicate that SN 2023ixf is a Type II supernova, an explosion that occurs after a massive star runs out of nuclear fuel and collapses
