Individuals who make extraordinary contributions to science often begin as regular people with a passion. This was certainly the case for Alan Guth, the physicist responsible for our understanding of how the universe formed after the Big Bang. Guth’s love for physics was sparked in high school and continues to drive his work today as a professor at MIT. Listen to learn more about his journey from a small town in New Jersey to physics textbooks around the world.

The sun is a star that sits at the center of our Solar System. It provides heat and a gravitational pull for all of the planets that orbit it. Scientists have long believed they knew what the sun was made up of and how it worked. When new evidence upset the balance between theory and observation, a solar physicist set out to reproduce the way the sun functions in a laboratory. Listen to hear more about how the sun works.

Last week NASA’s MAVEN probe began orbiting Mars in an effort to measure and map the Martian atmosphere. Today, Mars, known as the red planet, is bone dry and it’s atmosphere is being broken down by the sun’s solar winds, but evidence shows that it was once much more like Earth. From liquid channels to lake beds, there is clear evidence that Mars once had water as well as a magnetic field. So what happened to this water? These are the answers the MAVEN is searching for by mapping Mars’ current atmosphere. Listen to learn more about this important mission.
