NASA's Voyager 2 has left the solar system. For the second time, a space probe has crossed the heliosphere, the bubble of protective particles and magnetic fields created by the Sun---the Solar Wind.

According to the Jet Propulsion Laboratory at CalTech, scientists at the Lab compared data gathered by instruments on the probe. It had crossed the outer edge of the heliosphere on Nov. 5th when the signal dipped abruptly. Voyager 2 was now interstellar space. Voyager 2 carries an instrument that will provide first-of-its-kind observations of this gateway into space. Its twin space probe, Voyager 1, crossed the same solar system boundary in 2012.

Voyager 2 is now more than 11 billion miles from Earth. JPL engineers still communicate with the craft as it begins this new phase of its journey. Data from its instruments, traveling at the speed of light, will take over sixteen hours to reach Earth.

Both Voyagers carry a golden record containing mathematical symbols, photographic images, and recorded music from Earth. The record, produced by Carl Sagan and his team, will coast onward for millions of years towards separate points in space. If it were ever to be discovered, the discs might represent the only remaining remanants of human civilization.

Here's Carl Sagan speaking about the recording project in 1980, 38-years before Voyager 2 left our solar system.

Googbye to the Voyagers on their journey's of discovery!
