Probing the Interiors of Giant Planets via Seismology
Quick fact
In 1995, astronomers used the orbiting telescope EUVE to detect oscillations on Jupiter, and later missions like Cassini recorded similar pulsations on Saturn, revealing their internal rotation and composition.
Why this is interesting
You can't dig into Jupiter, but its vibrations act like a planetary heartbeat—answering questions about what's inside. How do scientists listen to that rhythm?
