The Banana and Whirling Dervish Nebulas (NGC 3199 and NGC 3247)

The NGC 3199 Nebula is an emission nebula located in the constellation Carina, approximately 12,000 light-years from Earth. It's known for its peculiar "shell" structure, caused by the interaction between stellar winds from massive stars and the interstellar medium. This nebula is a valuable field of study for understanding the physical and chemical processes occurring in star-forming regions and in the interaction between stars and their environment. NGC 3199 also hosts a Wolf-Rayet star, a massive and evolved star that contributes to shaping the nebula with its intense radiation and powerful stellar winds.

Discover the NGC 3247 Nebula, also known as the "Whirling Dervish Nebula"! Located in the Carina constellation, approximately 5500 light-years from Earth, this stunning emission nebula is a hub of active star formation. With its intricate spiral structures, NGC 3247 reveals the secrets of space chemistry and physics as new stars are born within. Its nickname, inspired by the swirling dance of the dervishes, highlights its beauty and motion. Detailed studies conducted with telescopes like the Hubble help us better understand the mysteries of the cosmos.

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.
