The Whale and the Hockey Stick

The iconic Horsehead Nebula, near Orion’s belt. Shot in narrowband over two evenings.

It’s really just a small portion of the Heart Nebula… that kinda looks like a fish. Maybe not the prettiest object in the cosmos, but it reflects a few technical accomplishments for me. About 20 hours of exposure time in total on this. Below I’m presenting it in a false-color “Hubble Palette”, as well as…

Messier 88, within the constellation Coma Berenices, is part of the nearby Virgo cluster of galaxies. And by “nearby”, I mean 50-60 million light years away! The light we’re seeing from this galaxy originated from the time of the dinosaurs. Telescopes are really time machines. There are many other galaxies surrounding M88, both smaller and…

Here’s my latest image of the “Bubble Nebula”, one of my favorite objects in our galaxy. That blue “bubble” is a shell of gas pushed out by the stellar wind of the bright star just right of its center. It’s a big star, 10-20 times larger than our sun. Its radiation is also illuminating and…

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 Pelican Nebula frankly isn’t a very attractive object as a whole, but if you crop it down to its heart, there’s a lot of interesting stuff going on. Look for little puffs in the image, or areas with spikes coming out of them. Those are Herbig-Haro objects – stars that are still in the…
