Messier 41

Um belo exemplar de aglomerado aberto, localizado na constelação de Canis Major. Messier 41 foi descoberto por Giovanni Battista Hodierna em 1654. Contem cerca de 100 estrelas e está localizado muito próximo a Sirius, a estrela mais brilhantes do céu noturno. Estima-se que tenha cerca de 25 anos-luz de diâmetro e uma idade entre 190 e 240 milhões de anos.
Em 325 A.C. Aristóteles descreveu um objeto que muitos historiadores afirmam, ter sido Messier 41, porém há muitas opiniões contrarias a essa afirmação, o que torna essa informação impossível de confirmar, porém, como fato histórico, teria sido o primeiro objeto de céu profundo de menor brilho observado na antiguidade.
A estrela mais brilhante do aglomerado, tem classe espectral K3 e magnitude aparente de 6.9, próximo ao centro do aglomerado.

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.
