New nebula discovered

#1

Post by KathyNS »


This very faint nebula was discovered last year. They are calling it a planetary nebula because of its shape, but its size and internal structures don't fit. Or it could be a supernova remnant, or something else entirely.

It is called StDr56, and it is located in Triangulum.

The photo, which is not mine, took nearly 60 hours of exposure time!

Interesting object. I like the characterization as a supernova remnant, but supposed they would have to know there was an SN there at one time. Or we'll have to start calling the Veil Nebula complex a PN :). Thanks for sharing the find, Kathy.

Looks like a supernova remnant - just doesn't seem to be an emission or reflection nebula.

Here is another article, by Phil Plait, about this object. Personally I can see some visual traits of a planetary nebula, though indeed it is a bit unique in appearance. Obviously bears more research.

Based on the coordinates used by Robert Pölzl, below is a chart I made in Sky Tools 3 showing its approximate position, It is plotted to stellar magnitude 12.0.

Coordinates: 02:07:17.41 +30:05:11.90 (J2000)

Thanks Kathy. Whatever it is it is very beautiful. I suppose we will eventually find out.

There is a type of soft bodied oceanic creature that looks like that.

That is an interesting object. I don't think I will get out my 60mm refractor in my Bortle 6 back yard to look for it though. ;)
