Mysterious ‘hum’ detected amid hundreds of quakes on Mars

A NASA robot measuring quakes on Mars has detected a strange-yet-familiar sound on the Red Planet, which some Earthlings might recognize as similar to “The Hum.”

The space agency’s InSight lander detected the sound shortly after it touched down on Mars in November 2018. The robot was using a seismometer tool to measure so-called “marsquakes” when it picked up the background “hum” of the Red Planet, NASA says. The lander also registered more than 400 quakes, confirming that Mars has plenty of seismic activity.

The humming sound is thought to be a combination of wind above and geological movement below the Martian surface, although the exact cause remains a mystery.

The so-called “hum” falls largely outside the range of human hearing, meaning future human visitors to Mars likely won’t be able to hear the Red Planet’s “song.”

The planet is also basically shivering with earthquakes as it gets colder, InSight’s readings show.

Researchers published their findings in multiple Nature-branded journals on Monday.

“We have discovered Martian infrasound and unexpected similarities between atmospheric turbulence on Earth and Mars,” they wrote in one of the studies.
