The Crescent Nebula
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…

Thor’s Helmet
This week’s target was Thor’s Helmet (NGC 2359), an emission nebula in Canis Major a rather distant 12,000 light-years away. It’s formed by a Wolf-Rayet star in its center, which is a crazy-hot star whose immense stellar wind is bunching up and ionizing the gases around it in these complex patterns. It’ll probably go supernova…

The Cone & Fox (revisited)
This is the Christmas Tree Cluster (turn the picture upside down and you might see it!) But the real focus here is the Cone Nebula at the bottom of the image, and the Fox Fur Nebula in the upper-right. Lots of red Hydrogen gas here being ionized by the young stars it formed. Also visible…

Space Jellyfish!
This is IC443, commonly known as the “Jellyfish Nebula” for obvious reasons! IC443 is a supernova remnant about 5,000 light-years away. This is a false-color, narrowband image consisting of a total of 20 hours of exposure time.

Globular cluster M92
Globular clusters are mysterious objects – they are dense clusters of stars, some containing hundreds of thousands of them. And they’re not within the plane of the Milky Way galaxy; they are scattered around it. How they formed is a bit of a mystery. Did they form with our galaxy, or are they the cores…

The Ghost of Cassiopeia
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.
