APOD: LDN 43: The Cosmic Bat Nebula (2022 Oct 31)

Post by APOD Robot » Mon Oct 31, 2022 4:06 am

Image LDN 43: The Cosmic Bat Nebula

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.

You should look at NGC 7129. Looks like a ghost!

OOh that's spooky! Just out of curiosity, concerning the names of nebulae, does the letter D in LDN 43 means Dark Nebula, and the B in LBN 7 means Bright Nebula?

Now,,, I know that NASA would never air brush or photo shop any of their space photos, but,,, this shot of the bat nebula is so real looking,, Even down to the facial features,, Very artistic looking,,, Very appropriate for Halloween,, :D

I was going to answer this with the links and found Chris had already answered. So I added the links.

To catch a bat in the house just get a tennis racket and a hand-held fishing net. Scoop the bat and seal the net with the racket. Release it outdoors. It will fly away uninjured.

I sneaked up on it with a shoe box against the wall! slid a cardboard between box and wall; took him outside and released him! worked for me! Similar to yours, except I don't have a net & don't play tennis! 8-)

Well, I hope this star-bearing creature of the night has its IR sensors set to maximum.
Ultrasonic radar won't be much use for navigating out there in the deep vacuum. Large-scale Halloween hazard . . .
