Voyager 2 Creeps Closer to the Edge of the Solar System | WHAT REALLY HAPPENED


Voyager 2 Creeps Closer to the Edge of the Solar System

And at the beginning of November, the team noticed a sharp decline in the number of particles encountered — but not all the way down to nearly zero, where it will remain after it leaves our neighborhood. That means that the spacecraft still has a ways to go before scientists can finally declare it free of its home solar system.

The new data adds to the first warning of Voyager 2's impending departure, which came from the probe's High Energy Telescope, which measures high-energy particles. Those particles become more prevalent as a spacecraft leaves the solar system.

The spike in energetic particles is a signature of the probe gradually losing the protection of a bubble around our sun called the heliopause. That bubble is formed by the solar wind, a constant stream of charged particles that is born in the sun, quickly accelerates in the star's atmosphere and then sets off across the entire solar system.
