The Bubble Nebula
11 light years away, the “bubble” itself is formed from the solar wind of the large, hot star inside of it. Imaged with narrowband filters.

On December 21, 2020, something really special happened in the sky: Jupiter and Saturn had an approach so close that it only happens every 800 years or so. They were so close in the sky that to the unaided eye, they looked like a single, bright star. This led many to proclaim it to be…
As with any form of photography, getting a good shot is largely about being in the right place at the right time. When it comes to photographing the planets, sometimes that means getting up at a painful hour. Both Mars and Uranus are nearing “opposition” – the point where they are directly across from Earth…
It’s not the title of a children’s story – it’s a pair of galaxies 30 million light-years away that look like, well, a whale and a hockey stick. Officially their names are NGC 4631 and NGC 4656.
These past couple of nights, I revisited the Wizard Nebula – home of a star cluster about 7,000 light-years away within the constellation Cepheus. This is a false-color image in the “Hubble Palette” where red, green, and blue represent ionized Sulphur, Hydrogen, and Oxygen emissions respectively. Can you see the “wizard”? Hint: he’s lying on…
If you point your telescope outside of the Milky Way, you’re almost guaranteed to pick up very distant galaxies, because there are just so many of them out there. This patch of sky inside Cancer is a cluster of galaxies called Abell 671. If you click the image and look at it full size, you’ll…
NGC253 is most commonly known as the “Sculptor Galaxy,” because it’s found within the constellation Sculptor. You probably haven’t heard of Sculptor – that’s because it is considered a Southern-hemisphere constellation, and it’s only visible in the US from Southern states such as Florida. It’s also known as the “Silver Coin Galaxy.” It’s part of…
