35 years on, we are now in interstellar space!
Jason Leci

The depiction of outer space in movies is something that leaves the inquisitive ones like me fascinated. And as an anonymous churning out words for a living on the blue planet, the news that Voyager 1 has now entered interstellar space couldn’t fill me with more pride than it already has!

Launched in 1977, the Voyager 1 has been a carrier of crucial information that has made us more aware of distant planets that make up this solar system. And although the spacecraft had already crossed into interstellar space in August 2012, the researchers at NASA have announced it only recently. Analyzing the oscillation pitch of the vibrations from an explosion on sun, the spacecraft has been deduced to be bathed in a plasma density which is around 40 times denser than the outer layer of the heliosphere, something which only interstellar space will exhibit. The spacecraft has also sent a sound recording of these ionic vibrations while being 11 million miles away. The sounds are eerie and levitating and inadvertently manage to pique one’s curiosity.



Having treaded into territory anew, the presence of Voyager 1 is a milestone in itself and provides us with the opportunity to understand the workings of interstellar space. The sounds of interstellar space and the exploration possibilities have given me major goosebumps and left me eager to see what comes next!
