Technically this nebula is called IC63, but its common name “The Ghost of Cassiopeia” seems much more timely, given Halloween is just around the corner!
Imaged all night last night, mostly in true colors with some Hydrogen emissions added in to enhance it.
The Dumbbell Nebula (M27) is what’s called a planetary nebula – but it has nothing to do with a planet. This shell of gas was blown out by a dying star; once it started to run out of Hydrogen to burn, it expanded and blew out the gases you see here. The star then collapsed…
It doesn’t take much imagination to see a ghost leaving a trail of ectoplasm in this cloud of Hydrogen gas, lit up by the bright star Navi. To keep with a spooky and ethereal theme, I photographed this object in monochrome using only a Hydrogen-alpha filter.
Hoag’s Object is the weirdest galaxy I know of; it is a “ring galaxy” – a very rare galaxy type that’s just a galactic core of stars, surrounded by a ring of stars that’s seemingly disconnected from its core. This galaxy has always captured my imagination. Just look at this image from the Hubble Space…
This is the Tulip Nebula in Cygnus, but see that shell-like structure just above it, to the right a little? That’s the bow shock wave of Cygnus X-1, a stellar-mass black hole! It’s one of the most powerful X-ray sources in the sky – but don’t worry, our atmosphere protects you from it. 20 hours…
This is a weird little cluster of galaxies – there are four in all, and each one is completely different. There’s a weird, S-shaped one that must have been messed up by its neighbors in the past, a somewhat normal-looking spiral galaxy, and elliptical, and another one that’s viewed edge-on. Galaxies that have interacted with…
Yeah, it’s been a couple of months since we’ve done a live star party online, or posted any new pictures. That’s just summertime in Central Florida for you – it’s been too cloudy to do any imaging or observing. The skies should start clearing up more in a couple of months, and we have every…
