NGC 3372 is a well-known brightly glowing nebula complex in the constellation of Carina, also known as the Eta Carinae Nebula. It is about 7500 light-years from Earth and has a diameter of about 300 light-years and is considered one of the most impressive celestial objects in the southern sky.

The nebula complex includes various objects, including the Keyhole Nebula, the Homunculus Nebula (a type of nebula surrounding Eta Carinae itself), and the open star cluster Trumpler 16, which contains some of the most massive and hottest stars in our galaxy. Trumpler 14 is a young star cluster containing some of the hottest and most massive stars in the Milky Way. These stars ionize the surrounding gas, producing the nebula's characteristic red glow. The Keyhole Nebula is a dark keyhole-shaped cloud within the nebula complex that blocks the view of the Trumpler 14 star cluster beyond.

This emission nebula is also known for the Eta Carinae star system, which is one of the brightest and most massive stars in the galaxy. It consists of two stars that orbit each other and periodically vary in brightness. Eta Carinae became one of the brightest stars in the night sky due to an extraordinary eruption in the 19th century.

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.
