A few questions about nebulae in DECaLS images

  • Abe_Hoekstra by Abe_Hoekstra

    There are a few DECaLS images with what seems like faint nebulae. I collected 4 of them in a discussion:

    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.
