The galaxy M106
The larger galaxy in this image goes only by the boring name “M106”, but it’s anything but boring. About 23 million light-years away, M106 is pretty similar to Andromeda in its size and brightness. But M106 is a lot weirder. In addition to its slightly warped shape, M106 is the home of a giant water-vapor…

Just an obscure little cloud of hydrogen.
This nebula goes by the unassuming name of SH2-9. It’s part of a larger complex of clouds known as the Rho Ophiuchi complex, but you don’t often see people focusing on this part of it. It’s a challenge to image from my location, as it’s very low in the sky in a light-polluted direction. There…

The “Bubble Nebula”
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…

The Whale and the Hockey Stick
It’s not the title of a children’s story – it’s a pair of galaxies 30 million light-years away that look like, well, a whale and a hockey stick. Officially their names are NGC 4631 and NGC 4656.

Revisiting the Northern Pinwheel Galaxy (M101)
Somehow I’ve neglected to go back to one of the showcase galaxies of the spring sky with newer equipment and software: M101, the “Pinwheel Galaxy.” Located about 21 million light-years away within Ursa Major, this relatively close galaxy shows lots of active star-forming regions revealed by red HII gas. Those red spots are nebulae in…

So. Many. Galaxies.
If you point your telescope outside of the Milky Way, you’re almost guaranteed to pick up very distant galaxies, because there are just so many of them out there. This patch of sky inside Cancer is a cluster of galaxies called Abell 671. If you click the image and look at it full size, you’ll…
