NASA has just confirmed that one of it's many spacecrafts recently heard a "hum" from outside of our solar system...

Going on to prove yet again that there is so much more out there beyond planet Earth.

What exactly could this all mean? Well, here's the full story...

Now, when it comes to outer space, the solar system, and the great beyond...

NASA are well and truly the experts.

The National Aeronautics and Space Administration is an independent agency of the U.S. federal government responsible for the civilian space program, as well as aeronautics and space research.

Some of the world's best scientists, engineers, astronauts, and cosmonauts have been working tirelessly for NASA since it was formed in 1958 to try and learn more about outer space and what is beyond our humble home planet.

And there's absolutely no denying how far they've come in the last 6 and a half decades.

Since its establishment, most U.S space exploration efforts have been led by NASA, including the Apollo Moon landing missions, the Skylab space station, and later the Space Shuttle.

NASA is also supporting the International Space Station (ISS) and is overseeing the development of the Orion spacecraft, the Space Launch System, and Commercial Crew vehicles.

And alongside all of these achievements...

NASA's global team continue to thoroughly research outer space and the possibilities of other universes and worlds out there.

The things that NASA has found over the years are truly remarkable...

And many of their findings have strongly suggested that there is life outside of Earth, such as discovering water on Mars and picking up radio signals from billions of light-years away.

Pretty fascinating, right?

Well, something even more eerie has just been discovered and people are amazed, to say the least.

A NASA spacecraft has picked up a strange "hum" outside of our solar system, according to The Independent.

Voyager 1 is the most distant human-made object ever, as one of a pair of spacecraft launched towards the edge of the solar system forty-four years ago.

Its journey has taken it right to the edge and beyond – and it is now flying through the "interstellar medium" beyond our own sun's influence.

​Instruments onboard the spacecraft that attempt to analyze that interstellar medium have heard a "constant drone"...

Which appears to be the noise of the universe beyond our own neighborhood.

The drone appears to be emitted by interstellar gas or plasma waves that are out in the largely empty space between the stars.

"It's very faint and monotone, because it is in a narrow frequency bandwidth," said Stella Koch Ocker, a Cornell doctoral student in astronomy, who found the emission.

"We're detecting the faint, persistent hum of interstellar gas."

The findings suggest there is more going on in interstellar gas than scientists had previously thought.

Scientists are not entirely sure what low-level activity could be causing the noise, but they have suggested it might be the result of "thermally excited plasma oscillations."

Researchers hope to use the drone to understand how the interstellar medium interacts with the border of the solar system, and how that border – known as the heliopause – is shaped by the wider interstellar environment.

Although Voyager 1 is now spectacularly distant from us - fourteen billion miles away, to be precise...

It can only send back limited amounts of information.

Researchers receive about 160 bits each second from the spacecraft, much less than the in itself now relatively limited twenty-one kilobits it could deliver when it first set off.

Simply amazing!
