So gorgeous! Here's the NASA article to go with the pic.

This striking image captures the interacting galaxy pair known as Arp-Madore 2339-661, so named because they belong to the Arp-Madore catalogue of peculiar galaxies. However, this particular peculiarity might be even odder than first meets the eye, as there are in fact three galaxies interacting here, not just two.
The two clearly defined galaxies are NGC 7733 (smaller, lower right) and NGC 7734 (larger, upper left). The third galaxy is currently referred to as NGC 7733N, and can actually be spotted in this picture if you look carefully at the upper arm of NGC 7733, where there is a visually notable knot-like structure, glowing with a different colour to the arm and obscured by dark dust.

3/26: Public night is cancelled tonight due to clouds. We'll try again next week.
Wed. 4/16: We'll be open from 8:30 - 9:45 tonight!
We'll be open April 8th for the eclipse, too, with solar filters and projections of the Sun. Find us at Bridgewater State University's Science and Mathematics Center.
Wed. Nov. 8 - Observatory closed due to cloud cover. We'll try again next week.

The Black Eye Galaxy (M64) is a relatively nearby spiral with an extraordinary amount of dark dust partially obscuring its nucleus. Red hues peeking out in these dust lanes are caused by reddening when the dust scatters the bluer light from stars embedded within it. The color difference between the center and spiral arms is due to an average age difference between the stars in these locations--blue stars have short lives, so as the star population ages the overall color appears more red.
So far, the forecast this Wednesday doesn't look good, but we'll wait til that day to make the announcement. Stay tuned for August public night announcements, too!
STEM Education, Astrophysics Research, Astrophotography, and Outreach located at 24 Park Ave., Bridgewater MA. You'll find us on the two outdoor balconies on the 5th floor, and you'll find our official website here: https://www.bridgew.edu/center/case/observatory .
