NASA brought in August 1977, the spacecraft Voyager 2 on the market. For nearly four decades, it has found its way out of the massive bubble called the heliosphere, which is created by the sun and contains our entire solar system. This happened about a year ago when we traveled to interstellar space and left our system forever.
This week, several new research papers have been published based on data returned by Voyager 2, revealing some interesting things about the boundary between our solar environment and the vastness of interstellar space.
Some of the more interesting references concern the observation of plasma in interstellar space and the fact that it is much denser than plasma in the heliosphere. This makes sense because it is very cold in interstellar space. Voyager 1
After Voyager 2 left the heliosphere, scientists expected a dramatic decrease in the number of charged particles detected. This proved to be the case for Voyager 1, but it was different for his twin, and it seems that the region where Voyager 2 leaked is "leaking." Voyager 2 observed some of the particles that are typically confined to the escaping heliosphere into the interstellar space.
"The Voyager probes show us how our Sun interacts with the material that fills most of the space between stars in the Milky Way," Voyager Project Scientist Ed Stone said in a statement. "Without these new data from Voyager 2, we would not know if what we saw with Voyager 1 is characteristic of the entire heliosphere or specific to the location and time of the crossing." Technology used for decades in space is still one-piece and much less functional, but here we are, and NASA's trusted little probes still work.
