NGC 4027 — One-Armed Galaxy

This is not the most inspiring subject so I didn't go to town with lots of captures and processing. This object is quite close to the famous Antennae Galaxies NGC 4038 and the Windblown Galaxy NGC 3981. So it is quite understandable to overlook this target.

NGC 4027 is a barred spiral galaxy located in the constellation Corvus. It is known for its peculiar appearance, featuring a single prominent spiral arm, which makes it quite unique compared to typical spiral galaxies. This asymmetric structure is believed to have been caused by a gravitational interaction with a nearby galaxy.

The galaxy is located at a distance of approximately 75 million light-years from Earth. It has an apparent magnitude of around 11.5, making it visible with amateur telescopes under dark sky conditions. NGC 4027 has a bright central region, and its spiral arm extends outward, showcasing intricate details and stellar formations.

The interaction with another galaxy, possibly NGC 4027's companion galaxy NGC 4027A, has likely influenced its morphology and triggered star formation. Such interactions between galaxies can lead to the redistribution of gas and dust, the formation of new stars, and the creation of unique structures.

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.
