NGC 7331

NGC 7331 is a captivating spiral galaxy located approximately 45 million light-years away from Earth in the constellation Pegasus. Named after its catalog number in the New General Catalogue (NGC), this celestial beauty has intrigued astronomers for centuries.

Measuring about 130,000 light-years in diameter, NGC 7331 is similar in size to our own Milky Way galaxy. Its spiral arms, composed of billions of stars, dust, and gas, gracefully wrap around a bright central bulge. The galaxy's structure is akin to a spinning cosmic carousel, with stars orbiting the central core like riders on a merry-go-round.

What makes NGC 7331 particularly intriguing is its striking resemblance to the Milky Way. Studying galaxies like NGC 7331 provides valuable insights into the formation and evolution of galaxies, including our own. By observing their structures, compositions, and behaviors, astronomers can piece together the cosmic story of how galaxies like ours came to be.

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.
