NGC 1579

This object is an emission nebula located 2000 light years away in the constellation of Perseus at a declination of +35 degrees. This object spans 10 arc-minutes in our apparent view, which corresponds to a diameter of 5 light years.

This is a full narrowband (HOS palette) image with RGB stars. I first tried the SHO palette but I did not like the result.

The nebula is nicknamed the Northern Trifid Nebula. Trifid is Latin for "split into three parts", referring to the dark lanes "trisecting" the nebula. The Northern Trifid Nebula is smaller than the better known Trifid Nebula and lies much farther north in the sky.

NGC1579 is illuminated by the central reflected light of the small orange star near the center of the nebula. This star, named LkHα 101, is a hot star almost 10,000 times more luminous and 15 times more massive than the Sun, but it is heavily obscured by dust. It lies within a small, young star cluster.

Per its nickname, prominent dark dust lanes extend throughout the nebula. This nebula will not likely have a long life, since powerful stellar winds emanating from the stars will eventually blow the gas and dust away, leaving just stars behind.

A dark dust lane, visible only by the lack of stars, is seen extending from top to bottom of this image through the central emission nebula. Dust is also evident throughout the background, given most of the stars a slight orange tint.

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.
