Cosmic Silver Lining Nebula NGC 2313 and Bright Star V565

This image of the week shows the emission nebula NGC 2313 The bright star V565 – surrounded by four prominent scattering spikes – illuminates a silver, gas and dust fan-shaped veil, while the right half of this image is a dust-shaped nebula enclosed by a dense cloud. Nebulae with similar shapes — a star accompanied by a bright fan of gas — were once referred to as cometary nebulae, though the name is no longer used. 

The language that astronomers use changes as they become better acquainted with the universe, and the history of astronomy is bound by now-obsolete phrases to describe objects in the night sky, such as “spiral nebulae” for “spiral galaxies” or “inferior planets” for Mercury and Venus. 

Although the terminology of modern astronomy has become increasingly precise, the nature of objects in contact with astronomy can still occasionally puzzle astronomers. For example, if you look very closely, you will see a faded blue line across the centre of this image at the bottom right of the blue zone. It may be an asteroid, but it seems to be traveling too fast for such an object – making it one of the remaining mysteries of the night sky.

NASA recently shared a striking image of NGC 2313, an emission nebula 3,756 light-years away in the constellation Monoceros. The photo was shared by NASA on its official Instagram account and has received more than 1 million likes and 4000 comments so far.

Uninterrupted, emission nebula is a bright, scattered cloud of ionized gas capable of emitting its own light. NASA explains that nebulae have the size of imilar shapes where once called a “cometary nebula” because a star with a bright fan looks like a comet with a bright tail.

The caption to the image reads, “A cosmic cloud with a silver lining! @ NASAHubble captured this image of emission nebula NGC 2313 located approximately 3,756 light-years away in the constellation of Monoceros. The emission nebula is a cloud of bright, ionized gas that emits its own light. “

It also states that the bright star V565 (as seen in the centre of the image) features a silver, gas, and dust fan-shaped veil, while the right half of the image is obscured by a dense cloud of dust.  The nebula NGC 2313 was discovered on January 4, 1862, by the German astronomer Heinrich Louis d’Arrest.
