Right now, a 47-year-old spacecraft is whispering across interstellar space.

Right now, a 47-year-old spacecraft is whispering across interstellar space. Voyager 1 is more than 24 billion kilometres from Earth — so far that its radio signal, moving at the speed of light, takes over 22 hours just to get here. Twenty-two hours. For a signal that travels at the fastest speed anything in the universe can manage. It crossed the heliopause in 2012, leaving the Sun's bubble of influence entirely and entering the space between the stars. It runs on a nuclear battery, slowly fading, and somewhere aboard it carries the Golden Record — a message pressed into metal for whoever might one day find it. We built something that outlasted its own era and is still reporting back. Follow Deep Field Vault for more of the universe, one true fact at a time.
