A Nebulosa Cabeça de Cavalo - The Horsehead Nebula

A Nebulosa da Cabeça de Cavalo (IC-434) é uma das mais famosas nebulosas do céu noturno. Essa nebulosa escura se localiza na constelação de Orion, aproximadamente 1500 anos luz de distancia do Planeta Terra. Nebulosas escuras são grandes nuvens moleculares, que são pobres em Estrelas. Essas regiões bloqueiam o brilho de estrelas no fundo, criando um "buraco" no céu.

The Horsehead Nebula (IC-434) is one of the most famous nebulae in the night sky. This dark nebula is located in the constellation Orion, approximately 1500 light years away from Planet Earth. Dark nebulae are large molecular clouds that are poor in stars. These regions block the brightness of stars in the background, creating a "hole" in the night sky

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.
