Do aliens exist? And if the answer is ‘yes’, do they look like what we’ve all seen in sci-fi movies or do they defy all expectations? Where are the aliens, anyway? Could they live among us without our knowledge? Is anyone of us an alien? Philosophers, scientists, and people, in general, have always been asking themselves such questions, and with each year that passes, humanity seems closer to unveil the mystery.
NASA’s Voyager 1 Spacecraft began its long journey in space back in 1977. For now, the space probe is far beyond the boundaries of our own Solar System. While astronomers had always been hoping that the spacecraft will encounter any signature of little green friends from different parts of the Galaxy, a new discovery that CNET.com wrote about is granting some hope.

Faint and monotone hum beyond the Solar System

Scientists examined data from the Plasma Wave System of Voyager 1, and they found a low and constant pattering against its detector, and space raindrops were falling. The drops are plasma waves, also known as interstellar gas.
Stella Koch Ocker, who is a doctoral student at Cornell University and also the leader of the research, declared:

We’re detecting the faint, persistent hum of interstellar gas,
“It’s very faint and monotone, because it is in a narrow frequency bandwidth.

The space humming is most likely not caused by any extraterrestrial beings, but that doesn’t mean we can’t speculate. Many astronomers believe that the Universe must be teeming with life. However, researchers believe that the weak plasma waves are different from other detections that occurred in space.
The new study paper was published in the journal Nature Astronomy.
