Whether it comes from without or within, there are few things in this life that captivate our attention better than a brilliant, hot and colorful display. This weekend, have a listen to The Roots with John Legend, as they sing about
The Fire.
Deep off in the depths of space, although you won't find any stars burning a bright green color, you will find stellar remnants, or star corpses, glowing a brilliant green.

It was only a few months ago that both collaborations at the Large Hadron Collider in CERN -- CMS and ATLAS -- announced the discovery of a new particle at about 125-126 GeV of energy: something that looked an awful lot like what the Standard Model predicted the Higgs Boson should be.

When we look up at the night sky from a dark location here on Earth, somewhere around 6,000 stars greet you on a clear night.

This is just a tiny fraction of the hundreds of billions of stars that actually make up our galaxy, which makes sense, considering how large our galaxy is and how vast the distances between the stars is. You'd probably think that the stars we can see are pretty representative of the…

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.

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 --…

Although I may write to you exclusively in English, I am fully aware that around half of my readership comes from outside the United States, and that English is the first language of only about 40% of you. Like most Americans, I learned Spanish as my second language when I was in school, and then studied a few other in college, formally, and tried to pick up the language of any country I traveled to. But I am by no means fluent…

On the one hand, we have General Relativity, our theory of space, time, and gravity.

It describes the Universe on both large and small scales perfectly, from the hot Big Bang to our cold accelerating expansion, from vast superclusters of galaxies down to the interiors of black holes.

But General Relativity doesn't tell us everything. It doesn't tell us, for example, about…

Here you are, a human being, a grand Universe of atoms that have organized themselves into simple monomers, assembled together into giant macromolecules, which in turn comprise the organelles that make up your cells. And here you are, a collection of around 75 trillion specialized cells, organized in such a way as to make up you.

Welcome back to yet another Messier Monday! Each week, we're taking a look at one of the 110 fixed, deep-sky objects -- not to be confused with comets -- that made up Messier's original catalogue.

Today, we're going to take a look at Messier 52, one of the 33 open star clusters in Messier's catalogue, which happens to be right on the edge of the Milky Way galaxy. It's one of the easiest Messier objects to find, as to get…

One of the great joys I've gotten to experience from my life has gotten to come not only from teaching, but from watching what my students do long after they've left my classroom for good. It's not a joy (with its ups-and-downs) exclusive to me, as Musiq Soulchild would sing you with his song,
Teachme.
Yes, I've had former students who are currently…

When General Relativity supplanted Newton's work as our theory of how gravity works in the Universe, it didn't just change how we view how masses attract, it gave us a new understanding of what the questions where and when actually mean. It gave us the very fabric of spacetime.

What this meant is that no longer could we view objects like matter and radiation as existing in some fixed, grid-like…

Welcome back, for another Messier Monday here on Starts With A Bang! Each Monday, we've been taking a look at one of the 110 Deep-Sky Objects that make up the Messier catalogue, a mix of clusters, nebulae, galaxies and more, all visible from most locations on Earth with even the most basic of astronomical equipment.

Sure, there are entire worlds within our world that we never even give a second thought to. There's an entire subterranean Universe to explore, and you might get the feeling to do it if you listen to Mecca Bodega's rumbling sound, in
Underground.
But as soon as those tiny critters begin invading your house, the wonder goes right out the window. In fact, you probably haven't thought much about them in terms other than how-to-poison-them in a long time.

I've seen your kindness and your strength. I've seen the best and the worst of you. And I understand with perfect clarity exactly what you are." -Joss Whedon
I bet you love science; practically all of us do, whether we realize it or not. As children, we all live as scientists, born with no knowledge or experience of this world, but with inherent ability to learn and adapt.

Nature's phenomena will agree or they'll disagree with your theory. And, although you may gain some temporary fame and excitement, you will not gain a good reputation as a scientist if you haven't tried to be very careful in this kind of work." -Richard Feynman

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.

I no longer have any issues. It’s a bit like asking an astronomer, does he mind that a telescope does all the work?" -Vishy Anand
It used to be no contest. Even if a computer could perform million, billions, or trillions of calculations per second, a game like chess surely got too complicated too quickly for a computer to compete with humans. At least, that's what we used to think, but some things just don't stay the same, as…

It's always the ones you least expect that get you the worst, it seems. I went to bed last night excited that Asteroid 2012 DA14, a 200,000 ton asteroid, was going to pass within just 28,000 km (or 17,000 miles) of Earth's surface, which would make it the closest pass of an asteroid that large that we've ever observed.

The next time you watch the Sun descend through the sky, towards the horizon, you might marvel at how the Sun remains the same size all the way down. At just slightly over half-a-degree, the Sun appears to drop at a constant rate throughout the afternoon and into early evening.
But there are some small changes…

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.
