NGC 1055 (Gary Imm)

NGC 1055

This object is an edge-on spiral galaxy located over 50 million light years away in the constellation of Cetus on the celestial equator (0 degrees declination). Although it is over 100,000 light years in diameter, it is so far away that its apparent size to us is only 6 minutes. The awkward framing of this image is due to two extremely bright stars just off the top of the image which visually impacted the primary object.

This galaxy has a prominent glowing bulge in the center which made this object image very difficult and frustrating to process. The star stream from this bulge extends to the lower left and right. This entire central galaxy area has a distinct purplish cast. This cast is also present in other images from better telescopes. I imagine that this cast may be due to extensive Ha regions throughout this area. Note - don't ever Google "purple ha galaxy" - I didn't realize that galaxy hair was a thing.

A wide, mottled dark dust lane spans the entire width of the galaxy. Several tiny bright blue star clusters are prominent in the upper part of the disk. A thin, arcing blue stream of smaller star clusters is visible in the lower part of the disk, extending behind the bright bulge from our perspective. I thought that this arc might just be an artifact, but the thin blue structure is confirmed in images from much larger telescopes.

Looking closely, you can see that the galaxy disk is slightly warped. Astronomers believe that this bending of the disk may be the result of interactions with a nearby galaxy. Several faint tiny galaxies are visible in the background.

The refractors!

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.
