NGC 3628

NGC 3628 is a mag 10.3 unbarred spiral galaxy in Leo, part of the triplet with M65 and M66. It is estimated at 35 million light years distance. It was discovered by William Herschel in 1784. It has an approximately 300,000 light-years long tidal tail. The gravitional pull of the neighboring galaxies has most likely tipped the plane of NGC 3628 and made its central dust lane "wobbled" in appearence. Spectroscopic analysis of the stars and gas in the disk reveal interesting motion. The stars orbit the galaxy in the opposite direction of the gas. It is conjectured that galactic mergers have created this phenomena. Note the dim dwarf satellite galaxy beneath the main galaxy.

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.
