Something in the Nothing

Something in the Nothing | The Dancing Rest https://thedancingrest.com/2015/05/07/something-in-the-nothing/ "This is not a hole, or an empty patch of sky. Rather it is a dust and gas cloud (catalogued as LDN 1774) so dense that none of the background star light can pass through. Molecular clouds, like LDN 1774, will (most likely) eventually host starformation."

“This new image from the 2.2-metre MPG/ESO telescope focuses on a conspicuously dark, tentacle-like structure in our night sky.

This is not a hole, or an empty patch of sky. Rather it is a dust and gas cloud (catalogued as LDN 1774) so dense that none of the background star light can pass through. Molecular clouds, like LDN 1774, will (most likely) eventually host starformation.

We can ‘see’ through the cloud if we observe with longer wavelengths. Infrared, microwave or radio waves will penetrate the cloud. But just like you can’t see through a muddy window – light in the visible regime cannot pass through.

Indeed, astronomers have identified three infrared sources: a giant star, a planetary nebula and an unknown source towards LDN 1774.” -CB via [The Universe]
