The Statue of Liberty Nebula (NGC 3576) & nebula NGC 3603

Both these nebulae lie in the Carina-Sagittarius Arm of our spiral Milky Way Galaxy. Both are bright
emission nebulae, being energized by hot, young, massive stars embedded within them. But there is a
significant difference between them.

NGC 3576 (on the right, or west) lies some 9,000ly away, and is only 100ly or so from the famous
Great Carina Nebula, NGC 3372. NGC 3603, on the other hand, is at least 2x as distant, at approx.
20,000ly. It is partly obscured by NGC 3576’s nebulosity. NGC 3603 is regarded as the largest emission
nebula (H-II region) in our visible part of the Milky Way.

NGC 3576 gets its common name from the shape of the dark nebulae within it. It was discovered by
John Herschel in 1834. A few days later, he also discovered NGC 3603, but initially thought it was
possibly a globular star cluster. He revised his opinion to a nebula by the time he published his
observations in 1847.

I have used a H+O triband filter in an effort to display the nebula’s features more clearly.

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.
