Happy Anniversary, Voyager probes

Today the two Voyager probes celebrate their 30th year in space. Altough, 15.5 billion km (Voyager 1) and 12.5 billion km (Voyager 2) from home there won't be many participants if they started a party there.

For a quick imagination: Light which emits from the sun needs about 8 minutes to reach Earth. When Voyager 1 sends its data to Sector 001, the signal has a journey of more than 14 hours until it can be received by human devices.

For more info on this event and interesting details see the Voyager Homepage and the BBC Science News Article.
