NGC 5102

This object is a lenticular galaxy located only 12 million light years away in the constellation of Centaurus at a declination of -37 degrees. This 9.7 magnitude galaxy has a surface brightness of 12.6 It spans 8 arc-minutes in our apparent view, which corresponds to an actual diameter of 30,000 light years. We see the galaxy about 20 degrees from edge-on.

Lenticular galaxies are generally not spectacular, just a short step up from elliptical galaxies. But this one is interesting because it lies only 20 arc-minutes from the bright blue 3rd magnitude star Iota Centauri. The blue glow from this bright star is seen in the lower right corner of the image. Some have nicknamed this galaxy Iota’s Ghost because it lies in the glare of that bright star.

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.
