Explanation: A nearby star has exploded and telescopes all over the world are turning to monitor it. The supernova, dubbed PTF 11kly, was discovered by computer only two days ago as part of the Palomar Transient Factory (PTF) sky survey utilizing the wide angle 1.2-meter Samuel Oschin Telescope in California. Its rapid recovery makes it one of the supernovas caught most soon after ignition. PTF 11kly occurred in the photogenic Pinwheel galaxy (M101), which, being only about 21 million light years away, makes it one of the closest supernovas seen in decades. Rapid follow up observations have already given a clear indication that PTF 11kly is a Type Ia supernova, a type of white dwarf detonation that usually progresses in such a standard manner than it has helped to calibrate the expansion history of the entire universe. Studying such a close and young Type Ia event, however, may yield new and unique clues. If early indications are correct, PTF 11kly should brighten to about visual magnitude 10 in the coming weeks, making it possible to monitor with even moderately sized telescopes.

That galaxy, Messier 101, is approximately 21 million light-years from earth, so you're very right. It may have happened a long time ago.
You are correct. I would also add that it helps to find darker skies, away from bright city lights. Also, try to look before the full moon next appears. Allow your eyes to adjust to the dark before looking. The galaxy may be visible in binoculars, though you may need at least a six-inch telescope to detect the supernova.
That’s “vertically challenged person of non-color”...
I would say more like an 8 or a 10 inch. While you should be able to pick up the galaxy core easy enough, the star is still at -12(?) or so. Very wide field of view to find it,then a high power orth to see the star itself.
I’m going to name that one after my ex since it’s so far away, and I like far away.
And 21 million years ago, to boot.
Thanks for posting this.
The moon is new.
Nice, CC. Thanks most soonest.
