NGC 1097 in Fornax

Acquisition type: Electronically-Assisted Astronomy (EAA, e.g. based on a live video feed)

NGC1097 (magnitude +9.5) is a face-on barred spiral galaxy located 45 million light years away in Fornax - the 'Furnace'.

This is the Luminescence channel (240 x 30 secs) acquired 2 nights ago from outer SE Melbourne - I am still to process in the RGB colour channels.

An excellent example of a barred spiral galaxy, and a hot-bed for supernova, with 3 identified since 1992 in this galaxy. NGC1097 is also gravitationally interacting with the smaller satellite galaxy (NGC1097B) at lower left of centre, and 'much' deeper images can identify 4 tidal tails of stars from interactions with previous galaxies. NGC1097 is also a Seyfert galaxy with a highly luminous central zone surrounding a supermassive black hole of around 140 million solar masses (as measured by the Atacama Large Millimeter/Submillimeter Array - ALMA). Inflow of matter towards the central bar of the galaxy causes new stars to form and ignite in the central bright ring that is around 5000 light years in diameter (seen here as the bright spot within the centre of the galaxy).

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.
