NASA's "Insight" Mars lander has detected what has been described as mysterious rumblings" coming from the interior of the Red Planet.
Though nothing definitive has been determined, scientists believe that a sudden release of energy from the planet's core may be causing seismic events that have been received by Insight.
Though the phrase "Marsquakes" has been popularized in scientific circles, it is not believed that Earth's nearest neighbor has the same kind of tectonic plate surface, making the origin of the rumblings all the more curious.
Scientists have been waiting for this time of year to listen for Marsquakes, given that the winds of Mars usually calm down this season. But the NASA team knows they are working on limited time given that Insight is solar powered and the part of Mars where Insight is located is currently moving away from the sun.
