Listen closely. Do you hear a chirping sound? It’s not birds. It’s cosmic waves from outer space!

These are chorus waves. Scientists have heard these cosmic jams before. In January, they heard them in an unexpected place—62,000 miles from Earth! Chorus waves usually happen near Earth and other planets. Until now, they’ve never popped up so far from a planet.

If you were actually in space, you wouldn’t hear the chirping. Sound can’t travel through the void (nothingness). But scientists use computers to turn the waves into audio files. They can do this because of the frequency of the waves.

Frequency is the rate at which the waves arrive. The faster they come, the higher the frequency. Sound waves have a measurable frequency. So do these extraterrestrial chorus waves. Scientists can treat chorus waves like sound waves.

What do they hear?

Chirp chirp chirp!

But where the chorus waves come from has scientists scratching their heads. They once thought these waves could be detected only near planets. Some scientists thought these space sounds came from plasma in a planet’s magnetic field. (Plasma is a very hot form of matter. It can be found around stars and planets.) That plasma would get jostled around in magnetic fields. Its electrons would collide and make radiation. Then the chorus waves would form . . . at least, that was the theory.

Now scientists aren’t so sure. The latest signals come from a calmer part of space. They’re far from Earth’s magnetic field. So what’s making that sound?

Creation is full of puzzles to solve. Sometimes our old theories turn out wrong. But God invites us to keep searching and learning. The more we learn about His creation, the more we learn about Him!

Why? Ideas come and go, and our understanding grows and changes, but God’s works stand firm.
