Scientists have discovered evidence of gravitational waves, which show ripples in space and time. A new machine has made it possible for scientists to observe space in a whole new way. Recently, the machine picked up vibrations from the collision of two black holes. The discovery comes a few months after the very first detection of gravitational waves. With these tools, scientists can look at the universe in a new way. In this story you will hear the signal from the black holes converted from gravitational waves to soundwave.

Scientists recently announced a huge discovery—gravitational waves. The waves were detected when a collision of two black holes created ripples or waves, similar to ripples on a pond. These ripples were predicted by Albert Einstein a century ago as a part of his theory of relativity. Scientists have been working to detect these waves for decades and are excited about the information that can be learned from them. In this story you will hear what gravitational waves sound like and learn more about their discovery.

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.

Since the end of the space shuttle program and the beginning of independently funded space exploration, NASA hasn’t been launching many new spacecrafts. This is changing with a recent test flight for NASA’s new spacecraft Orion, which is designed to carry astronauts into deep space. Listen to this public radio story to learn more about Orion’s design and goals.
