globular cluster

The night sky is our window into the Universe beyond the Solar System, and in some cases, even beyond our own galaxy! Perhaps the oldest useful collection of deep-sky objects, the Messier catalogue showcases 110 of the most prominent night sky wonders, a full 42 of which are located beyond our own galaxy. Today, for Messier Monday, let's take a look at one of the true rarities of the Messier catalogue: a globular cluster that's not a part of our own galaxy!

Welcome back to another Messier Monday, only here on Starts With A Bang! With each new Monday, we take an in-depth look at a prominently visible random object from Messier's catalogue of 110 deep-sky curiosities, objects that range from stellar corpses to star-forming regions, to open clusters, globular clusters, distant galaxies, and even a few anomalies!

Welcome back to another Messier Monday here on Starts With a Bang! With 110 deep-sky objects making it up, the Messier Catalogue is the first comprehensive, accurate catalogue of faint (but not too faint) fixtures in the night sky. Each object tells its own unique tale, and is visible to amateur and professional skywatchers alike with even the simplest of equipment. Many of these objects were discovered by Charles Messier himself (or his assistant, Pierre Méchain), while others go…

Welcome to another Messier Monday, where each week we take a look at one of the 110 deep-sky objects that make up the Messier Catalogue! One of the most common type of object in this catalogue is the globular cluster -- referred to by Messier as a round nebula (since he couldn't resolve them into individual stars) -- of which there are 29 in the catalogue.

esiegel | December 31, 2012"I'd rather be a could-be if I cannot be an are;
because a could-be is a maybe who is reaching for a star.
I'd rather be a has-been than a might-have-been, by far;
for a might have-been has never been, but a has was once an are." -Milton Berle

So far, we've taken a look at a supernova remnant, a young open star cluster, and an active star-forming nebula, a testament to the great diversity of these faint, fuzzy objects that might be easily confused with a comet. Today…
