NGC 4435 & 4438 (Arp 120), The Eyes

NGC 4435 & 4438 (Arp 120 in Arp's Catalog of Peculiar Galaxies), aka The Eyes Galaxies (another silly name), are a pair of interacting galaxies located in the Virgo cluster. They are approximately 52 million light-years from Earth.

NGC 4435 is a compact barred lenticular galaxy that appears to be almost devoid of dust and gas. The galaxy contains a young population of stars on its central regions. Discovered by the Spitzer Space Telescope, the stars have an estimated age of 190 million years and may have formed as a result of the galaxy’s interaction with the neighboring NGC 4438. The galaxy’s bright core covers more than 50% of its diameter. Way more interesting to me is NGC 4438. It has long tidal tails and a very distorted disk, which has led to scientists classifying it either as a spiral or lenticular galaxy. The galaxy was likely once a spiral galaxy, but encounters with its neighbors over the last few hundred million years have left it damaged and badly deformed. NGC 4438 has an obscuring lane of dust just below its nucleus.

I wish I had better weather and more of it to really get a nicer image of NGC 4438. I find its shape, and the proposed reasons as to how it came to be, an interesting object to study. There are way better images of this pair on AB, but I was glad to finally have a chance to take an image of it myself. Galaxies are tough under Bortle 7+ skies.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
