Hickson 69

This is Hickson-69. The Hickson galaxy groups were cataloged by Paul Hickson, a Canadian astronomer, in the 1980s and are notable for having strong gravitational interactions between their members, causing the galaxies to distort, produce high levels of infrared and radio transmissions, and lots of new stars. If you look at the full size image, you’ll see about 50 galaxies: some face-on, some edge-on, a few distorted, some with hydrogen-rich rings and cores, etc.=x193iq5w xeuugli x13faqbe x1vvkbs x1xmvt09 x1lliihq x1s928wv xhkezso x1gmr53x x1cpjm7i x1fgarty x1943h6x xudqn12 x3x7a5m x1f6kntn xvq8zen xo1l8bm xzsf02u x1yc453h (the reddish features in the galaxies, captured with about 90 minutes of HA). The nearest are probably 250 million light-years distant, but some are probably a billion or so light-years away.

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.
