M106 (NGC 4258)

M106 (NGC 4258) is a large intermediate spiral galaxy in the constellation Canes Venatici and is about 22-25 million light-years (ly) from Earth.

The dwarf galaxy, NGC 4248 can be seen at the bottom of the image. In addition, there are numerous galaxies seen surrounding M106 in this image. The edge-on spiral galaxy, NGC 4217 (not shown; 60 million ly away from Earth) is believed to be a companion galaxy to M106.

One of the things that makes this galaxy very interesting is its active nucleus is classified as a Type 2 Seyfert, which has supermassive black hole at its center and is surrounded by discs of material falling inward toward the black hole. As the gas consumed by the black hole heats up it emits microwave radiation that gives the galaxy two extra arms visible in light images (not shown in this image) as wisps of gas oriented perpendicularly to the main (star-forming) spiral arms. There’s a beautiful image of these energetic gas arms here.

Additionally, M106 contains two supernovae, SN 1981K and SN 2014bc.

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.
