Nasa’s Voyager 2 has grown to be merely the second human-made mind make it to the space between stars.
Nasa declared the spacecraft left this particular region from the sun’s influence last month which is now after dark outer boundary of your heliosphere, about 11 billion miles from Earth. It can be trailing Voyager 1, which reached interstellar space C the vast, mostly empty area between star systems C in 2012.

Nasa said the evidence that Voyager 2 had left the heliosphere was made available from an onboard instrument called the Plasma Science Experiment, which measures solar wind. On 5 November, this device recorded a steep decline within the speed of solar wind particles, along with not observed any by any means since that date. Other instruments on Voyager 2 have corroborated the thought.
According to Nasa, the Voyagers will always be technically in this solar system. Scientists maintain your solar system stretches to the outer side of the so-called Oort Cloud, a sphere of icy bodies millions of miles away which could take many centuries to traverse.
“Working on Voyager makes me find that an explorer, because everything we’re seeing is completely new,” said John Richardson, a principal research scientist for the Massachusetts Institute of Technology. “We’re still seeing issues that no one has witnessed before.”

“Voyager incorporates a very special area for us,” said Nicola Fox, director with the heliophysics division at Nasa. “Our studies start in the sun and extend out over everything the solar wind touches. To achieve the Voyagers sending back information regarding the edge of your sun’s influence provides an unprecedented look at truly uncharted territory.”
The Voyagers launched from Cape Canaveral, Florida, in 1977. In spite of the long way, flight controllers will still be hold of Voyager 2.
