NGC 6951

Barred Spiral Galaxy NGC 6951:

NGC 6951 is a face-on Barred Spiral Galaxy of low surface brightness. It is classified as a Seyfert galaxy because of its bright star-like nucleus. Astronomers believe that Seyferts, and other galaxies with "active nuclei", harbor giant Black Holes at their center. As gas spirals into the Black Hole, it heats up and radiates as much energy as the rest of the galaxy. An image taken by the Hubble Space Telescope(HST) shows that NGC 6951 has a ring of new star formation surrounding the bright object in its center. This ring contains several bright knots that the HST shows to be giant star clusters. Other studies show that gas is flowing in toward the center through the bar structure, and this gas is being used in the star-forming ring.

Based on the published red shift, a rough distance estimate for NGC 6951 and supernova 1999el is: 75,000,000 light years, with the galaxy being 85,000 light years in diameter.

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.
