Spiral Galaxies are among the most beautiful objects in the night sky, and the Pinwheel Galaxy is a great example. The gigantic spiral disk stretches across 170,000 light-years, making it nearly twice as large as our Milky Way galaxy. The galaxy’s spiral arms are sprinkled with patches of star-forming nebulas (the pinkish regions), where new stars are being born. Intense radiation from the newborn stars ionised the mother clouds(mainly made of hydrogen), causing them to glow pinkish red.

For me, the structure also speaks to the beauty of cosmological evolution. In our universe governed by the second law of thermodynamics, although matter eventually falls towards chaos, orderly structures can temporarily arise, and great beauty can emerge in the process.

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.
