"Tomorrow is the most important thing in life. Comes into us at midnight very clean. It's perfect when it arrives and it puts itself in our hands. It hopes we've learned something from yesterday." -John Wayne There's a lot to look forward to on the precipice of the new year, and many of us will be up until midnight to ring it in. Well, if you're up that late, why not step outside and take a look at one of the deep-sky wonders of the Universe that won't be visible in the early part of the night for months! This Messier Monday, a near-moonless sky will greet you until the pre-dawn twilight, and…
"The proverb warns that 'You should not bite the hand that feeds you.' But maybe you should, if it prevents you from feeding yourself." -Thomas Szasz But on this Messier Monday, you're lucky enough that you're about to be introduced to one of the great northern galaxies of the Messier catalogue that is feeding itself! There are 110 deep-sky, non-transient objects that make up the Messier catalogue, and a full 40 of them are galaxies, the most numerous and most distant of all the types of objects catalogued by Messier.

"I should like to lie at your feet and die in your arms." -Voltaire Every object that we look at for Messier Monday has its own flavor, its own qualities, and its own unique characteristics. By far the most numerous of the 110 deep-sky objects making up the Messier catalogue are the galaxies, of which there are 40. It's best to observe them on moonless nights, as their surface brightness is spread out across a large area, and even a crescent Moon's presence in the night sky can make all but the brightest of these galaxies invisible to the eye, even in good equipment.

"The battle, sir, is not to the strong alone; it is to the vigilant, the active, the brave." -Patrick Henry It's not a good idea to showcase a galaxy for you every Messier Monday, considering that even a crescent Moon can render most of them completely unobservable. Now that the autumnal equinox has passed, however, a very special spiral will be visible after sunset for the next six months or so in a relatively nondescript part of the night sky. Out of the 110 deep-sky objects that comprise the Messier catalogue, a full forty of them are galaxies, although today's object wasn't recognized as…
"It is by going down into the abyss that we recover the treasures of life. Where you stumble, there lies your treasure." -Joseph Campbell It took Charles Messier and his assistant, Pierre Méchain, a lifetime to scan and survey the sky for all the permanent deep-sky objects visible in their telescopes that could possibly be confused for comets on first class. More than 200 years later, these 110 deep-sky objects are among the best seen and most wondrous sights of the Universe, accessible to anyone with a decent telescope and dark skies. This Messier Monday, let's look the farthest into the…
"We find them smaller and fainter, in constantly increasing numbers, and we know that we are reaching into space, farther and farther, until, with the faintest nebulae that can be detected with the greatest telescopes, we arrive at the frontier of the known universe." -Edwin Powell Hubble With 110 deep-sky objects scattered throughout the heavens, the Messier Catalogue provides skywatchers across the globe with a number of spectacular targets, from nearby nebulae and clusters to spectacular, distant galaxies. Each Monday, we spotlight a new one right here. Image credit: Rolando Ligustri,…
"We dance round in a ring and suppose, but the secret sits in the middle and knows." -Robert Frost It's time again for another Messier Monday! To kick off each week, we've been taking a look at one of the 110 deep-sky objects that make up the Messier catalogue. Compiled in the 18th Century to help skywatchers avoid these fixed night sky wonders (so that they could better hunt comets), these represent some of the most viewed and easily visible nebulae, star clusters and galaxies visible from our home world.

"Yes, indeed, if humankind — from humble farmers in the fields and toiling workers in the cities to teachers, people of independent means, those who have reached the pinnacle of fame or fortune, even the most frivolous of society women — if they knew what profound inner pleasure await those who gaze at the heavens, then France, nay, the whole of Europe, would be covered with telescopes instead of bayonets, thereby promoting universal happiness and peace." -Camille Flammarion Welcome back to Messier Monday here on Starts With A Bang, where each Monday we take a detailed look at one of the 110…
"Upon one occasion, while engaged upon a seven-foot mirror, he did not remove his hands from it for 16 hours together." -from Caroline Herschel's obituary Welcome to another Messier Monday here on Starts With A Bang! Each Monday, we highlight a different one of the 110 deep-sky objects that Messier catalogued so that comet-hunters wouldn't confuse these permanent fixtures with transient comets. But each object has a unique, remarkable story in its own right. Image credit: The Messier Objects by Alistair Symon, from 2005-2009. Out of the 110 objects, a full forty of them are galaxies…
"When you run the marathon, you run against the distance, not against the other runners and not against the time." -Haile Gebrselassie Welcome to a very special Messier Monday, which just happens to be the twenty-first consecutive week we've taken a look at one of the 110 fixed, deep-sky objects that Messier and his collaborators catalogued to avoid confusion with comets. Image credit: Tenho Tuomi, of his completed Messier Marathon. Today's Messier Monday is very special, because today is the new Moon closest to the vernal equinox. Each year, on (or very close to) the vernal equinox --…
"This seems to be the law of progress in everything we do; it moves along a spiral rather than a perpendicular; we seem to be actually going out of the way, and yet it turns out that we were really moving upward all the time." -Frances Willard As spring gives way to summer here in the Northern Hemisphere, one of the most beloved sights of the night sky becomes ever more prominent: the Big Dipper. (Image credit: NASA, ESA, Z. Levay (STScI) and A. Fujii.) These seven bright stars shine high above the horizon after sunset, and will continue to do so over the rest of the Spring and all Summer…
Last week, Jamie (my significant other) came home from work and told me about a conversation she had with her coworker, Chris. This week she asked another one, Miguel, whether he had any questions about Astronomy, Physics, space, etc. This week's question comes from Miguel: What is a galaxy, anyway? Why does it look like a big bright fuzzy star? And why are there different types of galaxies; shouldn't they all be the same? This might come as a surprise, but 100 years ago, it was pretty much accepted that we were the only galaxy in the Universe. In fact, there was a great debate in 1920 on…
