The power of a Star

At one point in time this dust cloud that resembles a Witchhead looking upwards was actually a star, blown up thousands of years ago, all its dust and debris scattered across the vastness of space. This nebula contains a huge amount of carbon monoxide and other gases too. The colour is caused not only by blue colour of its star (Rigel), but also because the dust grains reflect blue light more efficiently than red. A similar physical process causes Earth's daytime sky to appear blue.

What is really interesting here is the Blue giant star Rigel (The foot of Orion) with its intense heat is lighting up this cloud thus making it glow and reflecting light into space. Rigel is an Arabic name meaning (Foot), which is the foot of Orion the hunter. Most stars were named by the Arabs millennia ago. A time when Europe was in chaos, turmoil and War, The Arabs thrived and grew into knowledge, prosperity and wisdom.

This is the faintest object ever taken by my Telescope, the most challenging and difficult to process. Each exposure took 15 minutes, the total time of exposures was 11 hours over 4 nights.

Spooky as it looks, The Witchhead nebulae is brilliant and overwhelming in beauty and wonder.

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.
