M65

M65 (also catalogued as NGC3623) is a spiral galaxy located in the constellation Leo. It is classified as an intermediate spiral galaxy, which means its core structure falls somewhere between barred and unbarred. The existence of a central bar is uncertain because the galaxy’s oblique orientation makes confirmation difficult.

M65 and M66 were discovered by Charles Messier in 1780, and along with NGC3628, these form the famous Leo Triplet of galaxies. These galaxies are gravitationally interacting, which causes structural distortions, although M65 appears to be the least disturbed member of the trio.M65 is located approximately 35 million light years from Earth. It is approximately 100,000 light years in diameter and is estimated to contain some 200 billion stars, which puts it on par with our Milky Way galaxy. There is only a small amount of new star formation occurring within the arms and this appears to be a relatively recent occurrence stemming from external gravitational disturbance. Aside from this, the dominant yellow hue of the galaxy suggests it is composed of mostly older stars.

M65 is easily seen visually through most small telescopes, and depending on the field of view, it may be possible to see all three members of the Leo Triplet in the same field.

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.
