Voyager 1 goes Interstellar

[PutraenusAlivius]

Apparently, the spacecraft Voyager 1 is now in interstellar space and has left our Solar System.

TBH, this is the moment I've been waiting for. I wanted to see Voyager 1 go Interstellar when I'm alive and that wish is granted.

If you don't know Voyager 1, here is it's details.
Voyager 1, which is part of the Voyager mission with it's sister spacecraft Voyager 2, is launched in 1977 and is still working with some instruments turned off to preserve power.

How did NASA know this? In Voyager 1 and 2, there's a Plasma measuring device. The solar plasma caused by solar winds would decrease and interstellar plasma would increase.
Guess what? It did. Voyager 1 detected it. Voyager 1 is expected to be dead in 2020 as it cannot power any more instruments. Voyager 1 is also expected to be joined in Interstellar space by it's sister ship, Voyager 2.

After 36 long years, this spacecraft is the first ever spacecraft to leave our Solar System and the farthest manmade object.

I'm really happy. I just found out today.
