NGC 7331 is a spiral galaxy, probably not too dissimilar from our own (except that it lacks a bar), which is relatively nearby. (At a mere 49 million light-years, it's not in our own back yard, but it's just down...

NGC 5135 is a barred spiral, similar in some ways to NGC 1365. Both galaxies are members of the IRAS "Bright Galaxy Sample," meaning that they are very luminous in the infrared as a result of vigorous star-forming activity. Both have very...

VV114 is a very interesting galaxy. It's a major merger of at least two big galaxies. If I might go out on a limb, it may even be an advanced merger (on the left) currently strongly interacting with another galaxy...

Here are images of two more galaxies. These weren't taken during the current run, but in a previous run. Last November, I was also down at CTIO with some students. I was doing blazar work on the 1.0m telescope (not...

I apologize for my silence of the last few weeks; real life gets busy at times. This time, I was in a crunch finishing up things before running off to an observing run at the CTIO Observatory in Chile. That's...

M82 is a galaxy that's relatively near to the Milky Way. It's not in our own local group, but it's in a nearby group of galaxies (the "M81 group"), and is only about 12 million light-years away (which is close...

This is an image of NGC 6744, taken with the South African Large Telescope. NGC 6744 is a classic spiral galaxy, and appears similar to how the Milky Way would look if we were able to get outside of the...

This is really what the sky looks like if you go out side at the right time of night and the right time of year at the CTIO observatory in Chile.
