The Sunflower Galaxy (Messier 63, M63, NGC 5055) is a spiral galaxy located 25 million light years away in the constellation of Canes Venatici (the Hunting Dogs). It comprises a central disc surrounded by short spiral arm segments. The disc is around 100,000 light years in diameter.

The galaxy was first observed by Pierre Méchain on 14 June 1779.

Messier 63 exhibits very faint extended features just visible in this image. These are probably the result of gravitational interactions with nearby galaxies.

Messier 63 was photographed between 4 May and 2 June 2019 from an imaging rig in Spain that is privately-owned and remotely-operated by Barry Wilson and me.

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.
