Flying Faster Than the Speed of Sound

Did you know sound has a speed? It is how fast the waves of sound travel through the air. It is very fast. 

When an airplane gets close to flying that fast, the air ahead of it starts to compress. Shock waves form on its wings and drag increases dramatically. 

The first person to fly faster than the speed of sound, or to break the sound barrier, was Chuck Yeager.

Voyager Record

Songs in Space

Two Voyager spacecraft were launched in 1977. After exploring the outer solar system, both travelled into interstellar space. Each carries a record that includes images, sounds, and music from Earth, in case they encounter another intelligent civilization.

The records include messages from U.S. President Jimmy Carter and U.N. Secretary-General Kurt Waldheim, greetings in 55 languages, and a sound essay about life on Earth. The records also include music of different types from around the world, from classical symphonies, to traditional and folk music, to blues, and rock n’ roll.

Creating Sounds Out of Data from Space

Scientists can use the signals gathered by telescopes to produce the kinds of images that we’re used to seeing – but some scientists also turn that data into sound. This is known as sonification. Play the video for an example. 

These sonifications were created by the Chandra X-ray Center, which is operated for NASA by
the Smithsonian Astrophysical Observatory.
