Waiting 16 million years to see something really seems like an infinite amount of time, that's exactly how long it took for the photons to reach the telescope. Sixteen million light-years from Earth, in the constellation Hunting Dogs, a galaxy is moving away from us at 308 km/s. The light from this galaxy left 16 million years ago and, at this time, the galaxy has already traveled several million km further. These photons have been traveling at the speed of light (300,000 km/s) for 16 million years to make it possible for us to see them and create this image. M94, its name, is a barred spiral galaxy (like our Milky Way) peculiar because it has two distinct zones, an inner ring, about 30,000 light-years in diameter, and an outer ring, about 45,000 light-years in diameter. In the inner ring there are constantly forming stars while, the outer ring, contains about 23 percent of the galaxy's mass and contributes 10 percent to the formation of new stars, this outer ring, however, forms stars much faster than the inner ring because it is more efficient. This ring, after careful study, was found to have been created by distortion of the inner ring.
The galaxy is presented “face-on” to us so we can see some of its reddish-blue nebulae inside.

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.
