Summary

Story summary

Scientists have developed methods to translate cosmic signals into sound, allowing us to hear space.
In space, sound cannot travel because matter density is low.
Data from electromagnetic signals, plasma waves, and gravitational ripples can become audible.
For example, the Sun would roar at 100 decibels if sound could propagate.
The first recorded sounds from space were detected by Karl Guthe Jansky in 1933.
