A few questions about nebulae in DECaLS images
-
by Abe_Hoekstra
There are a few DECaLS images with what seems like faint nebulae. I collected 4 of them in a discussion: http://talk.galaxyzoo.org/#/boards/BGZ0000001/discussions/DGZ0001u74
Is it possible DECaLS can detect nebulae that haven't been seen before? Do these nebulae consist of gas, dust or both? And what I think is most intriguing: is it possible to detect never before seen supernovae remnants or expelled gas layers of stars?
I always like to look for quirky stuff. If the science team is interested I might continue looking for them.
Cheers,
