Mmmmm, Donuts

SN 1987AThis is one of the early images of the remnant of a recent supernova. At 168,000 light-years distant, SN 1987A was the closest supernova observed in almost 400 years when astronomers caught sight of it in 1987.

  1. See, this is the root cause of one of my pet peeves.

    Yes, supernovas leave donut-shaped images. This is because (as I’m sure our gentle host is well aware) the supernova blasts out a thin spherical shell of debris, the image appears as a ring because we’re looking at the edge of the sphere, the debris is comparatively thick from our viewpoint.

    This has morphed into the Death Star giving off a donut shaped ring when it explodes. Yes, it bugs me.
