M33 is a spiral galaxy found 3 million light years away in the constellation Triangulum. With a diameter of about 60,000 light years, it is the third largest galaxy in our local group after our own galaxy the Milky Way and M31 the Andromeda galaxy which M33 is thought to be a gravitationally bound companion to. It is home to some 40 billion stars, not many compared to the 400 billion found in the Milky Way and the 1 trillion in Andromeda.

M33s future is un-certain, it is thought to of had a close encounter with M31 in the past 2-8 billion years and may do again. It is also possible it may participate in M31s collision with our own galaxy in 4 billion years which may result in our galaxies merging, or it may be ejected from the local group all together.

Along the galaxys loosely wound spiral arms are massive regions of star birth, some of the largest known. These ionized hydrogen clouds, more commonly known as nebula are the same as those that are found and imaged by astrophotographers one by one in our own galaxy, except here we can see all that M33 has to offer in a single image including the massive nebula known as NGC 604. NGC 604 contains around 200 blue stars and is over 1,500 light years across, a monster compared to the Carina nebula, one of the Milky Ways largest gas clouds which spans only 300 light years.

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.
