Cosmic Noise

Space is silent. But if it had a soundtrack, this might be it. Put on headphones.

What Does Deep Space Sound Like?

Space is a vacuum. Sound can't travel through it. But NASA has converted electromagnetic waves from plasma in space into audio. The result is not what you'd expect — it's more like a low, groaning drone with occasional crackles and warbles. It sounds like a haunted machine.

The Sun emits a constant stream of charged particles — the solar wind — at about 400 km/s. When these particles hit a planet's magnetic field, they create currents and electromagnetic waves. NASA's Voyager and Cassini probes have recorded these waves and converted them to audio. The result is eerie: a low hum that rises and falls, like the ocean in a seashell but deeper.

This player doesn't play a real recording. It synthesizes something inspired by those recordings — a deep low-frequency hum with gentle noise, designed to feel like you're floating in space. There's no right or wrong way to listen to it. Put on headphones, close your eyes, and remember: the universe is not silent. It's just that your ears evolved to hear air, not plasma. If you had ears on the solar wind, you'd never sleep again.

Frequently Asked Questions

Is this real space audio?

No. Real space is a vacuum — sound can't travel. This is a synthesized approximation inspired by NASA's plasma wave recordings, which convert electromagnetic waves into audio.

What does the Sun sound like?

NASA has converted solar wind data into audio. It's a low, groaning drone with occasional crackles. Not music. More like a haunted machine. You can find these recordings on NASA's SoundCloud.

Is it safe to listen to loud?

Start low. The default volume is gentle. This is an ambient sound, not music. Use it for focus or sleep. Don't blast it through headphones at max volume — that's bad for your ears regardless.

What is this?

This is a synthesized soundscape. It layers a deep low-frequency hum (inspired by the Sun's 5-minute oscillations), gentle white noise (approximating solar wind particles), and random soft pulses (mimicking cosmic ray strikes).

It is not a real recording. Real space is a vacuum — sound cannot travel through it. But NASA has converted plasma wave data into audio, and it sounds something like this: a low, groaning drone with occasional crackles.

Use it for focus, sleep, or to feel slightly insignificant. 10 minutes should do it.
