Thor’s Helmet

This portion of the Veil Nebula, commonly called the “Witch’s Broom,” is part of a larger shell of gas known as the Cygnus Loop. It’s gases blown off from a supernova that exploded 10,000 to 20,000 years ago! The rich red and blue colors are real; this is not a false color image. Shot over…

This pair of galaxies gets its name from their shapes. Both are viewed edge-on, and from this perspective we can see how a past interaction between the two warped them both. About 6 hours of exposure time from the backyard observatory.

Our new home has clear views of the sky down to about 15 degrees from the horizon; which means some objects that are normally considered only visible from the Southern hemisphere just peek above our trees for a few hours. One such object is the galaxy Centaurus A; it’s an odd galaxy that looks like…

This was intended to just be an image of the galaxy M77 in Cetus, but quite a few other galactic photobombers showed up! The annotated image below guides you to the brighter galaxies in this image, but click on it to expand it, and you’ll find many other ones as well that are incomprehensibly distant.

Like the Bubble Nebula, and Thor’s Helmet, this is formed by the fast stellar wind of the extremely hot star at its heart – which interacts in complex ways from the wind left over from when this star was a red giant. This is roughly 5,000 light-years away. These images were taken over the span…

The galaxy M106 is an interesting one; it’s large and relatively bright – about the same size as Andromeda. And it’s in a busy part of the sky, within Canes Venatici, with lots of galactic neighbors. This image has been enhanced with Hydrogen emission data; that’s what the red dots and tendrils are. There’s one…
