Grand Design NGC7424

NGC 7424 is a barred spiral galaxy about 100,000 light-years in diameter, located about 37.5 million light-years from Earth in the southern constellation of Grus (the Crane), as it is moving away from us at about 939 kilometers per second. It is called a "grand design" galaxy because of its well-defined spiral arms. It is listed as a member of the IC 1459 Grus cluster of galaxies, but is instead believed to be gravitationally unbound to any cluster.

This multi-armed galaxy is seen almost directly head-on, and its structure and diameter make it quite similar to our own galaxy, the Milky Way. It is classified as "SAB(rs)cd", which means that it is intermediate between normal spirals (SA) and strongly barred galaxies (SB) and has rather open arms with a small central region.

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.
