Eerie sounds from Mars reveal the first evidence of this phenomenon on another planet

A groundbreaking recording from another world may reveal clues to the secrets of one of our closest cosmic neighbors.

For the first time, tremors were discovered on another planet.

On April 6, NASA's Mars InSight Lander recorded a weak seismic signal in a so-called "Marsquake". On Tuesday, NASA Audio released the quake, preceded by the sounds of the howling Martian winds.

"The Martian Sol 128 event is exciting because its size and longer duration match the profile of the moonquakes discovered during the Apollo missions on the lunar surface," said Lori Glaze, director of the Planetary Science Division at NASA -Headquarters.

I have collected background noise so far, but this first event officially opens a new field: Marseismology, "said Bruce Banerdt, investor of InSight, NASA's Jet Propulsion Laboratory (NAS) in Pasadena, California.

The seismic activity was observed with InSight's Seismic Experiment on Internal Structure (SEIS) to give an insight into the planet's inner activity.

"We have been looking for a signal for months like this This is what we are waiting for, "said Philippe Lognonné, SEIS Team Leader at the Institute for Physique du Globe in Paris (IPGP) in France." It's so exciting to finally have proof that Mars is still seismically active, and we look forward to it to share detailed results as soon as we had the opportunity to analyze them. "

" Recognizing these tiny quakes required a great engineering job v High-quality seismometers are often sealed in subterranean vaults to protect them from temperature and weather changes, "NASA said in a statement.

Since InSight can not bury a seismometer like Earth's people, the lander used a robotic arm to place a seismometer on the surface of Mars and cover it with a protective wind and heat shield to protect it from the extreme weather red planet

Although this is the first seismic activity discovered on any other planet, it is not the first time that tremors have been observed outside the Earth in our solar system.

During NASA's Apollo program in the late 1960s and 1970s, astronauts who landed on the moon left seismometers to help scientists in further research. These sensors have measured thousands of "moonquakes" and help scientists better understand the interior or the moon and how it originated.

These seismometers are no longer active, but new instruments can be installed on the lunar surface as NASA sends astronauts back to the Moon in the 2020s.

Mars and moonquakes have a different origin than trembling on Earth. Earthquakes are caused by the movement of tectonic plates, but neither Mars nor Moon has tectonic plates. It is believed that these earthquakes from another world are triggered by stress that builds up internally and eventually releases as energy near the crust.

Although different from earthquakes, they can still help uncover the secrets that lie beneath the surface of the planet.

"The seismometer can even tell us if there are any liquid water or swaths of active volcanoes under the Martian surface," NASA said.

Scientists believe they may have discovered additional Marsquakes in recent weeks. However, the data is still evaluated to determine the exact cause of the signals detected by the SEIS.

"We are delighted with this initial achievement and are keen to perform many similar measurements with SEIS over the next few years," said Charles Yana, SEIS Mission Manager at CNES () {
