IC 2948: The Running Chicken Nebula (APOD 18 Apr 2008)

Post by Indigo_Sunrise » Fri Apr 18, 2008 11:14 am

Today's APoD - IC 2948: The Running Chicken Nebula - found here:
http://antwrp.gsfc.nasa.gov/apod/astropix.html
mentions 'Thackeray's Globules'. Are these similar to 'Bok's Globules'? Or are any of these 'globules' so named for whomever discovers them? I haven't researched these 'globules', but will shortly. But anyone with info or knowledge on them, feel free to chime in.
Thanks in advance!

And gorgeous image, btw!

Sounds like golbules are part of starforming regions. :)

If you follow the link to Thackeray's Globules in today's APOD you can an explanation under the caption tab. This particular set of Bok globules were discovered by A.D. Thackeray. Wikipedia even pictures Thackeray's Globules in their discussion of Bok Globules. Another named Bok Globule is Barnard 68.

Right, I got that they are both most likely star-forming regions, but was curious whether there were multiple names for the same thing, or if they were slightly or majorly different.

Thank you both for the links. Wikipedia is where I started looking, too. Pretty informative.

Thackeray discover the Bok globules in IC 2948. It is Bart Bok who first first drew attention to such objects in 1947. So, yes, this dark region are Bok globules. (ref: http://hubblesite.org/newscenter/archiv ... k/2002/01/)
