NGC 2859

This object is a beautiful small barred lenticular galaxy located 80 million light years away in the constellation of Leo Minor.

The structure of this galaxy is fascinating. The bright core has a slightly less bright bar running through it, and is surrounded by a medium brightness ring. This ring is in turn surrounded by a dim larger ring, similar in diameter to our Milky Way. The apparent size of this larger ring is about 4 arc-minutes. Between the two rings is a very dim annular section which is virtually absent of stars at the two regions which are perpendicular to the bar axis. According to the Cambridge Galaxy Atlas, these two regions correspond to two Lagrange points of the bar potential for which no stable stellar orbits are possible.

Numerous smaller background galaxies can be seen throughout the image, including several tiny galaxies which can be seen through the bottom edge of NGC 2859.

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.
