Voyager 2 escapes from the solar system, and he tells NASA the secrets of interstellar space – BGR



NASA launched the Voyager 2 space probe in August 1977. It has been nearly four decades since they've escaped a massive balloon called the heliosphere, which is generated by the Sun and contains our entire solar system. He accomplished this feat about a year ago, traveling in interstellar space and leaving our system forever.

Several new scientific papers were published this week using data sent back from Voyager 2, and they reveal some interesting things about the border between our sunny neighborhood and the vast expanse of interstellar space.

Some of the more interesting notes include observations of plasma in the interstellar space and the fact that it is much more dense than plasma in the heliosphere. This makes sense since it is very cold in the interstellar space and this is something that Voyager 1

notices when it starts to emerge from the heliosphere back in 2012.

After Voyager 2 left the heliosphere, scientists were expecting a drastic drop in the number of charged particles he found. This turned out to be the case for Voyager 1, but things were not the same for his twin and it seems that the region where Voyager 2 is released is "permeable". Voyager 2 monitors some of the particles that are usually confined to the outflow of the heliosphere.

"Voyager probes show us how our Sun interacts with things that fill most of the space between stars in the Milky Way galaxy," said Voyager scientist Ed Stone in a statement. "Without this new data from Voyager 2, we would not know if what we see with Voyager 1 is specific to the whole heliosphere or specifically to the location and time when it passes."

spent decades in space, it's still in one piece, much less functional, but here are NASA's reliable little probes still doing the job.
