Arp 141 (Gary Imm)

Celestial hemisphere: Northern · Constellation: Camelopardalis (Cam)

Arp 141

This rarely imaged object, also known as UGC 3730, is a pair of interacting galaxies located 130 million light years away in the constellation of Camelopardalis at a declination of +73 degrees. This object spans 3 arc-minutes in our apparent view, which corresponds to a actual span of 120,000 light years.

This is an extremely interesting structure. At first glance this object looks like a reflection nebula. But upon closer inspection, the upper half of this object looks to me to be an elliptical galaxy. The lower half is a wildly distorted mess and its former galaxy type is anyone's guess - perhaps a former spiral galaxy? The bottom half has a strong blue tint, indicative of a large number of young stars initiated by this interaction.

On the right side of the image is the pretty blue spiral galaxy UGC 3705, with one arm reaching upward. This galaxy is the same distance from us as UGC 3730 and may be experience some disturbance from it. At the top of the image is another interesting galaxy, the blue irregular galaxy MCG+12-07-034.

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.
