#NASA: #Voyager2 has entered interstellar space after four decades

NASA's Voyager 2 space probe has now entered interstellar space. Launched in 1977, the spacecraft is now more than 11 billion miles from Earth. This is the second time a human-made object has reached this part of space.

Voyager 2 is now NASA's longest-running mission lasting 41 years. This boundary is where hot solar wind meets cold interstellar space, and it's called the heliopause. Mission scientists compared data from instruments on Voyager 2 to determine that the actual date of the crossing was November 5, when the solar wind particles around the probe dipped greatly, meaning it left the heliosphere.

Pretty amazing...

I just wonder how exactly NASA knows that Voyager 2 is still out there and functioning. I would have throught, that signal from that probe at that vast distance wouldn't reach Earth.
