You might think that we know it all, at least as far as knowing-it-all is possible. After all, we know that matter is made up of atoms, which are made up of electrons and nuclei, and the nuclei are made up of protons and neutrons, and then the protons and neutrons are made up of quarks and gluons.

Along with the electrons, the quarks and gluons are -- as far as we know -- indivisible, which places them among the…

Out there in space, whether we look with our eyes or with a telescope -- a far more powerful version of our eyes -- we find that the Universe is full of stars, galaxies, clusters, and luminous objects everywhere we look.

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!

esiegel | June 16, 2013"Illusion is the first of all pleasures." -Oscar Wilde
It's tough to tell fact from fiction, and sometimes just as hard to tell reality from illusion. As long as you're enjoying yourself this weekend, I'd have to agree with Buckwheat Zydeco, and say
Let The Good Times Roll.
But despite what these images you're looking at might seem to show, there's nothing rolling at all here.

One of the most difficult things to talk about, for any self-respecting scientist, is politics. Like all of you, I have my preferences, my opinions, and my vision for what a better world would look like. I'm also well aware that if I talked about all of them, there probably wouldn't be a single one of you out there who agreed with everything I had to say.

Biggest puzzle from afar
How unlike the other ones
Brighter than a billion suns
Twinkle, twinkle, quasi-star
How I wonder what you are." -George Gamow
The Big Bang is one of the greatest, revolutionary ideas in all of modern science, but it's also one of the most successful ideas as far as making predictions that have aligned with our observations of the Universe. Despite all of that, there are a whole bunch of people who'll read this (and more who won't) who aren't sure that the Big Bang is correct. Some people, in fact, don't even understand the definition of…

Welcome back to another Messier Monday, only here on Starts With A Bang! Each Monday, we take an in-depth look at one of the 110 deep-sky objects that make up the Messier Catalogue, the first accurate and comprehensive deep-sky catalogue of relatively bright, extended celestial objects that can be viewed with even the most primitive of skywatching equipment under good skies. Each one of these objects -- ranging from nebulae to star clusters to galaxies -- holds its own, unique story.

esiegel | June 9, 2013"A man's face is his autobiography. A woman's face is her work of fiction." -Oscar Wilde
It's an intense world out there, and life can leave you weary in many ways. And sometimes, making your way through each day makes it feel like the whole world is watching, and there's no hiding. Have a listen, this weekend, to The Basement's song,
I Just Caught A Face.
Sometimes, no matter how hard we try to put our best face forward, we come off as stand-offish (or worse) to the world.

You'd never know it unless you were one of about six people in the entire world, but today is a landmark anniversary for me. Three years ago, I was on summer break from teaching at my local college, when I got an email from the Royal Astronomical Society in England.

You've of course heard by now the news that Kepler, the most successful and prolific planet-finding mission of all time, has probably reached the end of its useful lifespan.

With nearly 3,000 planet candidates under its belt, including many approximately Earth-sized (and some even smaller), and many within their parent star's habitable zone, we now know that, at least planet-wise, we're not alone in our galaxy.

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.

esiegel | June 2, 2013"...because today, with cameras as pervasive as they are, there is no such thing really as professional photographers." -Marissa Meyer
Before you get irate, I don't actually agree at all with that quote above; I have no talent for photography at all and a tremendous respect for those who do, and who cultivate it to produce something beautiful. So this weekend, the most appropriate song I could find for you was by a group known as Camera Obscura, and their rather dark ballad,
Your Picture.
Why do I bring up photography today? Because one of my blog's biggest fans, Felicity, runs a fun little…

Imagine: you've worked hard all your life, through your primary and secondary school education, where you worked hard to get into a good college, through your undergraduate degree, where you found something you were passionate enough about that you wanted to study it even further, and then through graduate school, where you spent half-a-decade or more immersing yourself, non-stop, in an area of research in a field…
esiegel | May 29, 2013"The joy of life consists in the exercise of one's energies, continual growth, constant change, the enjoyment of every new experience. To stop means simply to die. The eternal mistake of mankind is to set up an attainable ideal." -Aleister Crowley
But the Universe itself experiences continual growth, constant change, and new experiences all the time, and it does so spontaneously.

One of the great arenas in the world that knows no international bounds are the performing arts in general, and music in particular. Some of my favorite musical innovations have come from not only foreign countries, but from mixing many different musical cultures together. This weekend, have a listen to this amazing collaboration between James Keelaghan and Oscar Lopez, whose work combines Irish, Flamenco, and Canadian influences together to create this…

I can't even express these things properly because I have to - I have to conceptualize complex ideas in this stupid limiting spoken language! But I know I want to reach out with something other than these prehensile paws! And feel the wind of a supernova flowing over me!" -Ronald Moore
Well, you probably don't actually want to feel the wind of a supernova flowing over you; trust me on this.

Well, I guess it's that season again. The charlatan who claims to have invented a cold fusion device -- the same device whose flaws were exposed here two years ago -- has just held an "independent test" of his device, and there's now a physics paper out claiming that this device works, and must be powered by some type of nuclear reaction!

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…
