Great Orion Nebula (Shailesh Trivedi)

Great Orion Nebula

Imagine you are on a space ship and have travelled a long 1400 light years from Earth. Tired from your journey, you see light that began travelling towards Earth when the Byzantine Empire flourished and Constantinople (modern day Istanbul) was its capital. Suddenly you come across an animal, what looks like an old beast that has been cut open with its innards spilling out. You can see its thoracic cavity, its heart has been removed; an empty void where it once existed. Its head dangling from the side of the body after it was severed. A casualty of war. As a result of this, there are gases and dust spewing from the torso where the head once stood high and tall. You just arrived at one of the most glorious deep sky objects in the Milkyway. The Great Orion Nebula is part of the sword of constellation Orion, the mighty warrior. This is a star nursery with at least 700 stars in various stages of birth and growth. Stars form when clumps of hydrogen and other gasses in the Hydrogen Alpha region (red color) contract under their own gravity. The clump grows larger and temperature increases by converting gravitational potential energy into thermal energy. With high enough temperature & pressure, nuclear fusion is ignited forming a star which emits sufficient energy to prevent further gravitation collapse.

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.
