Statue of Liberty Nebula - NGC 3576

The Statue of Liberty Nebula - NGC3576 - an emission nebula in the Sagittarius arm of our spiral galaxy, some 9000 light years distant.

Here two batches of data (acquired in 2018 and 2021) is combined to double the exposure on this object to 6 hours 36 mins.

Enormous loops of gas are expelled by dying stars. Star factories are embedded in the intensely illuminated portions of the nebula, whilst dense knots of dark gas (Bok globules) that comprise the head and arm of the statue are sites from which future stars will condense under gravity and ignite by nuclear fusion reactions. Outflowing stellar winds continually sculpt the nebula whilst ultraviolet radiation from young, newly birthed, hot blue main sequence stars ionise the hydrogen gas causing it to glow.

Polycyclic aromatic hydrocarbons have also been detected in NGC3576, and their presence in our sun’s formation nebula 5 billion years ago would likely have been an important step in the development of carbon-based life on earth.

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.
