NGC 1084

This object is a rarely imaged spiral galaxy located 60 million light years away in the constellation of Eridanus at a declination of -8 degrees. The 10.7 magnitude galaxy spans 3 arc-minutes in our apparent view, which corresponds to a diameter of 60,000 light years.

I like the classic subtle coloration of this galaxy - from yellow in the core to blue in the arms, with some purple in the HII regions. There are two bright spots in the core area, but it doesn't quite look like dual cores to me. I believe that the lower right "core" is likely a dimmer foreground star. The arms form a chaotic pattern, with irregular bright star portions interspersed with dark dust lanes. The galaxy disk is inclined at about 60 degrees from face-on. I am surprised at the lack of foreground Milky Way stars in the immediate vicinity of the galaxy.

A recent paper (Study of Star Formation in NGC 1084 - Ramya, Sahu & Prabhu, 2007) indicates that this galaxy has a much higher star formation than expected, which is likely causing the purplish tint to the galaxy. The paper also identified that the fuzzy patch just right and below the galaxy is in fact an interacting dwarf galaxy, which is likely responsible for initiating much of this star formation activity.

The galaxy to the lower left is 2MASX J02460680-0738033, located 0.5 billion light years away and having a diameter of 120,000 light years.

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.
