Messier 106

Discovered in 1718, Messier 106 (NGC 4258) is a large spiral galaxy found 24 million light years distant toward the constellation Canes Venatici. Visual magnitude is 8.4 and apparent size is 18’.

This active galaxy holds a super-massive black hole at its center. The black hole powers energetic emissions at essentially all observed wavelengths. Of particular interest is the pair of luminous jets seen flowing from the center at 8:00 and 2:00 in this image. The former appears particularly focused. These jets which are reveled here in light of excited hydrogen represent hot gas ejected from the black hole’s accretion disk which then collides with the cooler gas in the galaxy’s disk and halo. This process creates the appearance of four spiral arms, but only two contain star clouds. The other two being the gas jets. A smaller companion galaxy, NGC 4248 is seen at right.

This image was captured under high desert skies near Santa Fe, New Mexico, USA.

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.
