Voyager 1 Is Still Sending Data from Interstellar Space
The Voyager spacecraft as a tiny golden speck against the vast darkness of interstellar space with a faint signal beam stretching back toward a tiny distant Sun
Launched in 1977, Voyager 1 entered interstellar space in 2012 and continues transmitting data from over 24 billion kilometers away. Its radio signals, traveling at the speed of light, take over 22 hours to reach Earth.
Why Itβs Interesting
It is humanity's farthest-reaching object, running on less power than a refrigerator light bulb. The fact that 1970s technology is still functioning in interstellar space is a testament to engineering. Its Golden Record carries sounds and images of Earth for any civilization that might find it.
