Double Post: Mini Stars & Morning Micrometeorites on Mercury

Alliteration is accessible to all! Okay I’m done. Start some science! Really done this time.  Today’s double post covers the smallest of stars, still larger than most planets, and the only weather Mercury will ever have. Humans are naturally interested in the extremes, the biggest, smallest, fastest, hottest, coldest, and every other characteristic outlier.  With stars, being so huge and powerful, we are often more interested in the largest, hottest, and most energetic.  Though on the opposite end of the spectrum, Cambridge University astronomers have discovered the smallest star in the known universe. The star, a red dwarf, has the...

Blast From The Past

A supernova is the death blast of a giant star, far larger than our Sun.  Massive stars go out with a bang, outshining entire galaxies, allowing us to see them across the universe.  A supernova observed in 2013 occurred in a distant galaxy and took over 30 Million years to reach Earth, where the timing was perfect for us to observe and study it.  And now that it’s been studied, the explosion was truly the death of a giant. The supernova, named 2013 ej, was discovered in June 2013 in the galaxy M74 in the constellation Pisces.  It was the closest supernova...

1000 Things You Didn’t Know About the Universe #4: Most Stars are Small and Red

Welcome to a new series of posts that will characterize 1000 amazing facts about the Universe.  There is so much out there that we have yet to learn, and every day, astronomers across the globe are using their research to reveal the deepest secrets of the cosmos.  This series will look at the strangest, coolest, most exciting facts that we have discovered in hundreds of years of modern science. Fact #4: Most of the stars in the universe are red dwarfs smaller than our Sun. There is a leap of understanding that happens when a child learns that our Sun...

Astroarcheology – The Oldest Stars

A few hundred million years after the big bang, the first stars formed.  We aren’t exactly sure how, but we do know that they contained Hydrogen, Helium, and a little bit of Lithium.  These were the only elements in the entire universe at the time.  Within these first stars, the fusion of heavier elements began.  Oxygen, Nitrogen, Carbon, Iron, and all the other elements that make up everything we know formed Billions of years ago in these first stars and in their progenitors.  It was a slow process to produce these elements and seed them throughout the cosmos, but over...

The Most Beautiful Equation

Are equations beautiful? Does a mathematician see the machine code of the universe in the complex language they use? Does a Chemist see the flow of matter? Does a Biologist see the evolution of life? Does a physicist see the probabilistic nature of electrons? Many scientists would affirm their view that the equations that dictate their respective fields are artistic, in addition to logical.  So if equations can be beautiful, what is the most beautiful equation? Naturally, the most beautiful equation should be simple.  It should be somewhat intuitive, yet surprising in it’s result.  It should explain something fundamental about the universe,...

Milky Way Stars Interact Dynamically

Think about Earth and its population of over 7 Billion people. That’s 7 Billion people who wake up, breathe, live, think, experience, and interact with each other.  The sheer volume of interactions and variation in the human experience is staggering.  Every second you are alive these interactions are happening all around you, and far from you in any corner of the planet.  Millions of people right now feel sad, happy, ecstatic, broken, angry, tired, energetic, and everything in between. Now if we go beyond to the Milky Way, where there are more than 50 stars for each and every homo sapiens on...
