Globular star clusters are some of the most beautiful objects in the galaxy as well as some of the oldest objects in the galaxy. This cluster, NGC 1846 appears to be a bit of a showoff as it’s sporting a single emerald green star at the bottom right at six o’ clock.  How many of you yelled at your phones when you read that?  Hopefully quite a few of you because, of course, there are no green stars which means that what we have here is a beautiful line of sight planetary nebula which is a stellar corpse.  Well, hold on a minute there as well because that part of the equation isn’t quite settled either.  This planetary very well could be within the globular cluster based on what we know about it so far.  Also, if you look to about the eight o’ clock position you can spot a lone galaxy many millions of light years beyond.

If you have a small telescope or even a set of binoculars, hunting globular clusters can be extremely rewarding challenge and there are many of them out there, some 150-ish in the MIlky Way alone so go have a look!
