Triangulum Galaxy

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…

Formally Abell 33 or the even more catchy name PK238+34.1, the “diamond ring nebula” is a planetary nebula – that means it’s the gas blown off by a dying star, not too different from our own sun. This one’s interesting due to its almost perfectly spherical shape, its cyan color from ionized Oxygen gas, and…

Every year I try and do a better job of capturing and processing the Bubble Nebula in Cassiopeia. Here’s this year’s attempt. The Bubble Nebula is one of my favorite objects. Not only is it interesting scientifically (the bubble is the stellar wind of a hot O-type star blowing away the surrounding gases,) it’s also…

If you’re a fellow amateur astronomer, you might be curious as to how our “live star parties” on our Boldly Going YouTube Channel are produced. The more people doing this, the better! Here’s how it all works behind the scenes, which might give you some ideas on how to produce your own show. The Heart…

Like most globular clusters, M15 lies outside the plane of our galaxy, but is part of it – likely a remnant of the Milky Way’s original formation; a cluster of stars that just never got mixed in with the rest of the galaxy. M15 is one of the oldest, somewhere around 13 billion years old….

This is a somewhat obscure target; at 46 million light-years distant, it’s hard to capture much detail on it from Earth. But that’s what makes it interesting and challenging! Located within the constellation Ursa Major, this is a flocculent spiral galaxy notable for its massive central core. Look around in the background, and you’ll find…
