Bode's Galaxy and Cigar Galaxy - 2023

A recapture of 50 hours of narrowband on Bode's and Cigar since December 2022 blended with some wideband from 2021.

The Cigar Galaxy, M82, is observed edge-on, producing its 'cigar' shape. It is a starburst galaxy, having an unusually high rate of star formation, possibly influenced by its neighbour, Bode's Galaxy, M81. Radiation from the young stars compresses clouds of dust and gases, initiating further star formation. Supernovae in the core area occur at a rate of around 1 every 10 years. This intense activity fuels massive bi-polar fountains of ionised hydrogen gas and dust to be emitted into space, seen here in red.

Bode's Galaxy, M81, is seen face-on. It is a grand-design spiral galaxy about 12 million light years away. The bright red areas of hydrogen emissions in the spiral arms surround areas of star formation, which ionise the surrounding gas.

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.
