Yet another graphic showing the vastness of just our little galaxy. I remain in awe of it all.
sygazelle wroteVoyager 1 was launched in 1977 and has been travelling for 47 years, 8 months, 2 days (As of now) and about 'only' 16 billion miles away. Considering that astronomical distances are measured in light years, the probe is basically next door.Yet another graphic showing the vastness of just our little galaxy. I remain in awe of it all.
