IC477

IC 477 is a reflection nebula located in the constellation of Canis Major, approximately 1,300 light-years away from Earth. Reflection nebulae are clouds of dust and gas that reflect the light of nearby stars, causing them to appear as luminous patches in the sky.IC 477 is believed to be illuminated by the bright star Epsilon Canis Majoris, also known as Adhara. This massive, blue-white star is one of the brightest in the sky and emits intense ultraviolet radiation, which ionizes the gas surrounding it and causes it to glow.The nebula appears as a faint, bluish cloud against the backdrop of the Milky Way. It is elongated in shape, with a diameter of about 8 arc minutes. IC 477 is located near another prominent reflection nebula known as NGC 2359, which is sometimes called the "Thor's Helmet" nebula due to its distinctive shape.Overall, IC 477 is a beautiful example of a reflection nebula, and its delicate colors and intricate structure make it a favorite among astronomers and stargazers alike.

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.
