Messier 74 - The Phantom Galaxy

Link: https://svenarnold.com/2023/05/05/messier-74-the-phantom-galaxy/

Messier 74 or Phantom Galaxy is a good example of a 'grand-design' spiral galaxy. It is located in the constellation Pisces. This conspicuous spiral is a prototype of a grand-design Sc galaxy. It is more accurately classified as SA(s)c, i.e. as 'barless' without a 'ring structure'. The galaxy is about 32 million light-years away and is speeding away from us at a speed of 793 km/s. It is about 95,000 light years in diameter and contains many star forming regions, or HII regions. These are visible as small red spheres in the arms of the spiral galaxy. Three supernovae have been observed in M74 so far. The galaxy is thought to host around 100 trillion stars. In July 2022, the James Webb Space Telescope began observing M74 and took impressive images in the infrared range.

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.
