Good morning, Rallypoint, and welcome to the All Hallow's Eve edition of Astronomy Picture of the Day (APOD): "LDN 43: The Cosmic Bat Nebula." Lynd's Dark Nebula (LDN) 43 is found some 1,400 light years away in the constellation Ophiuchus. It is actually embedded in Lynd's Bright Nebula (LBN 7; the 'fog' surrounding LDN 43). We talked about 'dark' nebulae a couple of days ago...so what constitutes a 'bright' nebula?
The old red and blue photographic plates from the Palomar Observatory (California) again serve as the starting point. A 'bright' nebula can be either brighter on the blue (spectra) plate, similar brightness on the blue and red (spectra) plates, brighter on the red plate, or visible only on the red plate.
The light sources inside of LDN 43 are newly formed stars. The entire complex of gas and dust is roughly 12 light years long. Dr. Lynd published her catalog of bright nebula in 1965.

Thank you my space-exploration advocate friend and brother-in-Christ Maj William W. 'Bill' Price for posting the October 31, 2022 Astronomy Picture of the Day (APOD): Lynd's Dark Nebula (LDN) 43: The Cosmic Bat Nebula.

APOD Explanation: What is the most spook-tacular nebula in the galaxy? One contender is LDN 43, which bears an astonishing resemblance to a vast cosmic bat flying amongst the stars on a dark Halloween night. Located about 1400 light years away in the constellation Ophiuchus, this molecular cloud is dense enough to block light not only from background stars, but from wisps of gas lit up by the nearby reflection nebula LBN 7. Far from being a harbinger of death, this 12-light year-long filament of gas and dust is actually a stellar nursery. Glowing with eerie light, the bat is lit up from inside by dense gaseous knots that have just formed young stars.
