The Flaming Horse on a Sea of Grass

The Flame and Horsehead nebulae lie in the constellation Orion some 1500 light years away. The Flame nebula is near Alnitak, the easternmost star in Orion's belt, and is the brightest star in this image. Alnitak shines intense UV light into the Flame nebula, which excites the hydrogen gas clouds, producing the glow. Veins of dark dust and gas lie in front of the nebula giving the nebula an appearance of a flame.

The Horsehead nebula is a dark nebula of gas and dust that is silhouetted against the background H-alpha emission nebula. The glowing gas is energized by nearby star Sigma Orionis. Strong magnetic fields form streams of ionized Hydrogen gas that are visible above the Horsehead.

Both the Flame and Horsehead are a small part of a larger Orion Molecular Cloud Complex, which stretches from north of the belt of Orion to the sword near the Great Orion Nebula. This complex is a gigantic stellar nursery and is several hundred light years across.

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.
