NASA hears 'heartbeat' from Voyager 2 after blackout

NASA's distant Voyager 2 probe has sent a "heartbeat" signal to Earth after mission control mistakenly cut contact, the U.S. space agency said Tuesday Aug. 1.

Launched in 1977 to explore the outer planets and serve as a beacon of humanity to the wider universe, it is currently more than 12.3 billion miles (19.9 billion kilometers) from our planet - well beyond the solar system.
