NGC 4151 "Eye of Sauron" Galaxy

NGC 4151 is an intermediate spiral galaxy located in the constellation Canes Venatici. It is situated approximately 62 million light-years away from Earth. In addition to the central bar structure of NGC 4151, a series of star-forming regions can be observed along its spiral arms. These regions are abundant in gas and dust, giving birth to new stars. The spiral arms extend gracefully outward from the center, forming elegant curves. A ring-like structure is situated at the periphery, composed of loosely bound stars and dust.

To the bottom right and the right of NGC 4151 are spiral galaxies NGC 4156 and UGC 7188 (PGC 38811), respectively. Both of these galaxies are located at a distance of approximately 330 million light-years away from Earth.

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.
