What Voyager 2 Discovered After Spending a Yr in Interstellar Area

Solely two of humanity's spacecraft have left the photo voltaic system: Voyager 1 and Voyager 2 from NASA. Voyager 1 left the heliosphere in 2012, whereas Voyager 2 did the identical on November 5, 2018. Now, Voyager 2 is within the interstellar. house for one yr, and 5 new articles current this yr's scientific outcomes.

The heliosphere is a bubble-shaped space of ​​house with our Solar within the middle. Consider it as an inflated cavity crammed with plasma that comes from the Solar. The sting of the bubble is the place the plasma of our Solar offers option to the interstellar medium (ISM). Voyager 2 left the heliosphere and entered interstellar house about 18 billion kilometers from the Earth.

Every of the 5 paperwork comprises the outcomes of one of many 5 scientific devices of Voyager 2:

Two Plasma Detection Devices Detected by Two Magnetic Fields Detecting Fields

It’s outstanding that these devices, designed and manufactured a long time in the past, nonetheless work and accumulate new knowledge.

Voyager 2 took a long time to succeed in the heliopause, the demarcation between interstellar house and our photo voltaic system. Voyager 2 being the second spacecraft to succeed in it, it is ready to give us distinctive scientific details about this area. They’re distinctive as a result of Voyager 1 left the heliosphere at a unique location six years in the past. Voyager 2's knowledge can also be distinctive as a result of one in every of its devices, used to measure plasma, nonetheless works, whereas the Voyager 1 counterpart stopped working a long time in the past.

<p> The Solar operates on a cycle of 11 years and its efficiency adjustments throughout this cycle.There’s a debate in regards to the basic form of the h Nonetheless, throughout the 11-year cycle, measurement and form might change. Every of the Voyager probes encountered heliopause at about the identical distance, however Voyager 2 encountered the termination shock at about 1 billion. miles nearer to the Solar than the Voyager 1. The probes have left the heliosphere at completely different areas, and every of those probes has one thing completely different to inform us. </p>
<p> At current, Voyager 2 is in a transient area of house situated on the fringe of the heliosphere, not fairly in an undisturbed interstellar house. </p>
<p> Ed Stone is a professor of physics at Caltech and a challenge scientist for the Voyager program. In a press launch, he stated: "The Voyager probes present us how our solar interacts with the weather that occupy a lot of the house between the celebrities of the Milky Method galaxy. With out this new knowledge from Voyager 2, we’d not know if what we noticed with Voyager 1 was attribute of the complete heliosphere or particular to the place and time it was passing. "</p>
