NGC772 (AlBroxton)

NGC772

NGC772 (also known as Arp 78) is an unbarred spiral galaxy approximately 130 million light-years away in the constellation Aries. It is notable for possessing a single elongated outer spiral arm, which has likely arisen due to tidal interactions with nearby galaxies. At around 100,000 light years in diameter, NGC772 rivals the Milky Way Galaxy in size and is surrounded by several satellite galaxies including the dwarf elliptical, NGC770. Two supernovae (SN 2003 hl & SN 2003 iq) have been observed in NGC772. In a distance of some 130 Mio LY the galaxy appears rather bright at 10m3 in the night skies for a visual observer. The apparent size of 772 measures about 7.2 by 4.3 arc minutes which makes it a worthwhile target in a moderate telescope. Discovered on 27th of November 1785 by William Herschel 2 Supernovas have been observed ever since - photographically of course. These 2 SN showed up in 2003 - the image cannot reveal any sign of those SNs - too much time has passed meanwhile, and the remnants cannot be observed from earth any longer.

What makes that elliptical galaxy NGC 770 really special is its counter rotating core, which was described by professional astronomers in June 2005.

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.
