Horsehead Nebula

A nebula that looks like its name! Formally SH-308, this bubble of gas 60 light-years across is blown out by a hot Wolf-Rayet star at its center. It’s about 4500 light-years away in the constellation Canis Majoris. It’s quite dim, but if you could see it with bionic vision or something, it would be larger…

Our new home has clear views of the sky down to about 15 degrees from the horizon; which means some objects that are normally considered only visible from the Southern hemisphere just peek above our trees for a few hours. One such object is the galaxy Centaurus A; it’s an odd galaxy that looks like…

This is my first “dark nebula” – a cloud of dark dust obscuring the Milky Way behind it. You need dark skies to capture these things, which my remote setup in central Texas now provides. Well, at least when the moon isn’t up. Formally LDN1235, this is actually a much larger object that extends further…

M104 is known as the “Sombrero Galaxy” due to its visual appearance – but a deep, long-exposure image reveals its true structure. It’s a lenticular galaxy about 30 million light-years away, about 30% the size of our own Milky Way galaxy.

Formally SH2-155, the Cave Nebula lies about 2,400 light-years away within the constellation Cepheus. It’s part of a much larger region of gas and dust (called a molecular cloud). This region is mostly ionized Hydrogen, but there’s just enough Oxygen – blue in this image – to make for a pretty picture. Capturing that Oxygen…

As Halloween draws closer, this seems like an appropriate object to image: the “Witch’s Broom” nebula! Although to be honest, that bright star (Cygnus 56) looks more like an eye on some sort of fantastical, cosmic creature to me. In reality, it’s part of the larger Veil Nebula, which is a huge supernova remnant 1,400…
