IC 1623 (John Bozeman)

IC 1623

IC 1623 (also known as Arp 236 or VV 114) is a pair of interacting galaxies located some 250 – 300 million light-years away from Earth in the constellation of Cetus (the Whale). They are speeding away from us at over 6,000 kilometers per second. The galaxy pair consists mainly of intermediate age and young stars. The many young star-forming regions have probably been triggered by the first encounter of the merger. IC 1623 is very bright when observed in the infrared and classified as a pair of luminous infrared galaxies (LIRGs). It is approaching the final stage of its merger. Finally, a violent central inflow of gas will trigger intense starburst activity that could boost the infrared luminosity above the ultra-luminous threshold (more than 1012 as luminous as our Sun). The system will likely evolve into a compact starburst system. One of the two galaxies, the infrared-bright, but optically obscured galaxy IC 1623B (or VV 114E), has a substantial amount of warm and dense gas. Warm and dense gas is also found in the overlap region connecting the two nuclei.

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.
