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…

This image contains a few things! At the bottom is the Cone Nebula, at the upper-right is the “Fox Fur Nebula”, and in the middle is the “Christmas Tree” star cluster… you have to flip the image upside down to see that one. It’s a gorgeous region of active star formation in the constellation Monoceros….

The three galaxies in the constellation Leo (M65, M66, and NGC3628) are about 31 million light-years away. Each one is being seen from a different angle; the one viewed edge-on is also known as the “Hamburger Galaxy”. Each has been interacting with each other, and distorting the shapes of these galaxies through the complex dance…

This morning, my cat woke me up at 3 AM, and I noticed it was clear outside. But, the sun would start rising in just a couple of hours, so doing some super-long-exposure shot of a faint nebula wasn’t in the cards. However, globular clusters don’t take long to image, as they are relatively bright…

You’re looking at about 500,000 stars, balled up just outside of our galaxy. They are ancient; about 8 billion years old.
