A strange pulsing sound was detected on Mars recently, and scientists are scrambling to know where the sound is coming from.

According to a report, the NASA lander Insight sent some interesting data back to Earth of a mysterious magnetic pulsing sound which is said to have happened at midnight back on the Red Planet. The sound is described as “perfectly timed” and naturally raised the interest of researchers back on Earth. The source of the pulsating sound is so far unknown.

Now, scientists are trying to figure out if the sound is coming from underground or somewhere that’s nearer to the surface of the Red Planet. The most unusual part of the pulsating signal is that it happens during what’s considered an unusual time on Earth. The magnetic pulsating phenomenon is associated with the northern or southern lights back here on the planet.

Scientists assumed that the sound has something to do with the location of the lander and how it aligns with “the tail of the magnetic bubble around Mars.”

The tail is said to be interacting with the magnetic field of the alien planet which causes it to pulse. The next step would be for NASA to let the MAVEN orbiter do a flyby around the area to confirm their theory.

This information was released during the European Planetary Science Congress and the American Astronomical Society which took place in Geneva, Switzerland from Sept. 15 to 20.

The Insight lander has been gathering information about Mars since 2008 and was the instrument that first detected a Marsquake - an equivalent of the earthquake. It was also able to gather information about the temperature of Mars’ upper crust and came up with measurements of the Red Planet’s magnetic field.

Some might speculate that the pulsating sound could be alien in origin. This is quite possible since some NASA scientists believe that if there will be life on Mars they would have to come from underground where organic life is more protected against the Red Planet’s radiation and weak atmosphere.

“Survival on Mars really means going underground,” NASA astronaut and physiologist Dr. James Pawelczyk said. Taking this into consideration, life on Mars could mean aliens with tough shells or protection that could shield life not only from radiation but also from the extreme heat underground.
