Popular Science News | Voyager Spacecraft Leaves Solar System

Popular Science News | the Voyager Spacecraft is about to leave the Solar System and enter what is known as interstellar space. It is the first man made object to do this and the spacecraft is still expected to send data to Earth until 2025. A sister ship follows a billion miles behind the Voyager 1, which has been travelling for 35 years now.

Voyager 1 and 2 contain the famous gold plated disc, mastered using a now defunct format. The reason for this is in the event that either spacecraft is ever found by intelligent life-forms from other planetary systems they would have a snapshot of what earth is like. The discs carry photos of the Earth and its lifeforms, a range of scientific information, spoken greetings from people (e.g. the Secretary-General of the United Nations and the President of the United States) and a medley, “Sounds of Earth”, that includes the sounds of whales, a baby crying, waves breaking on a shore, and a collection of Earth music, including works by Mozart and Chuck Berry’s “Johnny B. Goode”.

Hopefully these aliens have a player or else the billions spent on this expedition will be wasted.
