NGC 2207

Link: http://www.manoprietoobservatory.com/gallery/galaxies/136

NGC2207 and IC2163, in the Constellation Canis Major at an approximate distance of 144 Million Light-Years, are passing by each other in a gravitational close encounter, with IC2163 behind the spiral arms of NGC2207 and moving in a counter-clockwise direction as its stars and gas are being stretched out in a 100 light-year long tidal tail. The two galaxies will continue to draw toward each other on their passing encounters, and merge billions of years into the future. Dust lanes of the larger NGC2207 sweep across the face of IC2163 and are silhouetted against its core, reddening the dust lanes of NGC2207 and the hue of the core of IC2163, which is about the same size as the Milky Way.

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.
