More from my bright tiny objects week….using ASI Air Auto-run
Something Dark Lurks Here? …Not really, its just like looking through a keyhole.
NGC 1999 is a dust-filled bright nebula with a vast hole of empty space represented by a black patch of sky, as can be seen in my photograph.
It is a reflection nebula(blue/white), and shines from the light of the variable star V380 Orionis.
It is located 1,500 light-years away from Earth in the constellation Orion. It was previously believed that the black patch was a dense cloud
of dust and gas which blocked light that would normally pass through, called a dark nebula. Further analysis with IR telescopes show it to be a
simple Hole in the reflection nebula showing the background of space, not a dark nebula.
The Immediate area surrounding the reflection nebula has large, fainter Dense dust clouds that can be seen better the H-Alpha
wavelength. This is just a quick 15 minute visible light shot from my back yard in Dayton, Ohio.
