Measuring The Universe With Gravitational Waves

In Gravity by Brian Koberlein1 Comment

Last year astronomers made the first detection of gravitational waves from the merging of two black holes. It gave us an entirely new way to view the cosmos. Now we aren’t limited by the emission and absorption of light by matter. We can explore the universe through ripples in the fabric of spacetime itself. Through recent observations we can study the most mysterious aspect of spacetime, known as dark energy. Read More

The History Of Einstein’s Most Famous Equation

In History by Brian Koberlein4 Comments

Albert Einstein is easily one of the most brilliant physicists who ever lived. His theories of general relativity changed our understanding of the cosmos, as did his work on quantum theory. But his genius has also led many to hold him up as a poor stereotype of science. The lone genius who ignores the science of his day to overturn everything with a simple brilliant theory. He’s become the icon of every crackpot who feels compelled to send emails to scientists about their idea that will revolutionize science if we only take the time to listen (and work out all the math for them). But as revolutionary as Einstein’s ideas were, they weren’t entirely unexpected. Other scientists had similar ideas, and developed similar equations. Take, for example, Einstein’s most famous equation, E = mc2Read More

A Big Science thank you to TV sizzle reel backers

In Big Science by Brian Koberlein0 Comments

The Big Science team is working hard this month to prepare a “sizzle reel” following a successful Kickstarter fundraiser that brought in $22,237 Canadian dollars. The sizzle reel will accompany a pitch to networks and streaming services for a possible television show about the employees and community at major science facilities around the world. Already, the team has made two research trips to the Green Bank Observatory in Pocahontas County, West Virginia. We’ll keep you updated as things progress. Read More

The Moon Once Had An Atmosphere

In Moons by Brian Koberlein0 Comments

For centuries humans have dreamed of traveling to the Moon. We achieved that dream in 1969, but found our sister world to be a dry airless rock. Most of the early stories of a journey to the Moon painted a very different picture, giving the Moon a breathable atmosphere, and perhaps even exotic life. We now know the Moon is barren of life, but there was a time when the Moon had an atmosphere. Read More

How To Detonate A Star

In Supernovae by Brian Koberlein4 Comments

The most powerful way a star can die is through a supernova explosion. Through nuclear physics and the pull of gravity, a star can be ripped apart, shining brighter than an entire galaxy for a brief moment of cosmic time. There are several kinds of supernovae, but one particular kind known as Type Ia is particularly interesting to astronomers. And we still aren’t entirely sure how they occur. Read More

The Sun-Centered Galaxy

In Milky Way by Brian Koberlein1 Comment

The stars in the Milky Way have generally circular orbits, and move through the galaxy at a speed of about 200 km/s. This is also true for our Sun. But how do we know this, given that our Sun is in the disk of the Milky Way, and we can only see our galaxy from our Sun’s vantage point? It all has to do with relative motion.Read More
