It's been a while since I posted, with weather issues and getting a new PC set up in the observatory. This is the Antennae Galaxy. The Antennae are undergoing a galactic collision. Located in the NGC 4038 group with five other galaxies, these two galaxies are known as the 'Antennae' because the two faint long tails of stars, gas and dust thrown out of the galaxies as a result of the collision resemble the antennae of an insect. The nuclei of the two galaxies are joining to become one giant galaxy. This image is 4 hours of exposure over 3 nights, May 2, May 10 and May 13. Click on the image for a closer view.
