open star cluster

While star clusters may dabble in a number of physically interesting things, there's one thing that they do above all others, and that is shine. For today's Messier Monday, where we spotlight one of the 110 deep-sky wonders of the Messier catalogue, let's take a look at one of the brilliant open clusters of stars that's recently formed in our neighborhood of the galaxy and that will appear all winter long: Messier 50.

Welcome back to another Messier Monday here on Starts With A Bang! The Messier catalogue was the very first accurate deep-sky catalogue with over 100 objects, finally topping out with 110 in its final form today. Compiled in the 18th century by Charles Messier and his assistant Pierre Mechain, this collection of fixed, deep-sky objects contains 110 of the brightest, most easily found and most spectacular sight in the entire sky.

Welcome back to another Messier Monday, only here on Starts With A Bang! The first accurate, large catalogue of fixed, deep-sky objects, Messier's 110-object-strong catalogue features galaxies, clusters, nebulae and more, all visible with even primitive astronomical equipment to skywatchers who know where to look. Each Monday, we highlight a different one of these for your enjoyment.

But in ourselves, that we are underlings." -W. Shakespeare
Welcome to just another Messier Monday here on Starts With A Bang! Each Monday, we're taking a detailed look at a different one of the 110 deep-sky objects that compose the Messier Catalogue, each one a different semi-permanent wonder of the night sky for our viewing pleasure here on Earth.

While we may not think of our galaxy as a hotbed of star formation -- and indeed it isn't compared to many, as it forms less than one Sun-like star per year…

Welcome to another Messier Monday here on Starts With A Bang! Each week, we take a look at the 110 deep-sky objects that comprise the Messier catalogue, the first comprehensive catalogue of fixed, deep-sky objects that could possibly be confused for potential brightening comets.

Welcome to another Messier Monday, where each week we take an in-depth look at one of the 110 deep sky objects that make up the Messier Catalogue! Messier was not the first person to try and make an accurate, large catalog of deep sky objects, but he was the first to successfully do so: most of his objects both actually exist, are deep sky objects, and had their positions recorded correctly.

Most, that is, but not all. Today, we'll be looking at the open star cluster Messier 48…

Who is powerful? He that governs his passions.
Who is rich? He that is content.
Who is that? Nobody." -Benjamin Franklin
Welcome to Messier Monday, where each week we take a journey into one of the 110 objects in the Messier Catalogue of non-cometary deep-sky objects. Ranging from stellar remnants to star clusters to globular clusters to distant galaxies and more, the Messier objects tell a rich and varied story that you can share in yourself through even the simplest of astronomical instruments.

esiegel | October 29, 2012"Something there is more immortal even than the stars,
(Many the burials, many the days and nights, passing away,)
Something that shall endure longer even than lustrous Jupiter,
Longer than sun or any revolving satellite,
Or the radiant sisters the Pleiades." -Walt Whitman
Last week, we kicked off our very first Messier Monday by spotlighting M1: the Crab Nebula. But with 110 different objects to choose from, the Messier catalogue represents some of the brightest and most universally accessible wonders of the night sky.
