The historic NASA probe is sending tons of info from billions of miles away.
Forty years have passed since NASA’s Voyager 2 was launched, and it sent back valuable info from interstellar space.
This is the second spacecraft in history to go beyond the heliosphere, according to BigThink.
The heliosphere is a bubble created by winds that are streaming from our sun, and that protects us from interstellar radiation.
New studies that are released by researchers confirm that Voyager 2 is traveling through the so-called interstellar medium (ISM) – this is the area between the stars.
It’s also important to mention that this is happening about 11 billion miles away from Earth, and scientists have been able to determine the craft crossing into ISM from the change in the plasma’s density.
Voyager 2 reaches the interstellar space
It’s been revealed that Voyager highlighted a transaction from the hot and low-density plasma of the solar wind to colder and higher-density plasma that’s associated with the interstellar space.
This was reportedly observed with Voyager 1 as well.
Caltech physics professor Ed Stone who is also a project scientist for Voyager, talked about the significance of what the probes uncovered:
“The Voyager probes are showing us how our Sun interacts with the stuff that fills most of the space between stars in the Milky Way galaxy,” he revealed in a press release.
He continued and said that “Without this new data from Voyager 2, we wouldn’t know if what we were seeing with Voyager 1 was characteristic of the entire heliosphere or specific just to the location and time when it crossed.”

In other news, scientists from NASA opened a sample that had been sealed and untouched for more than 40 years.
