Spacecraft Voyager 1 has officially entered interstellar space, although exactly when it left the heliosphere is still up for debate.m“This is the first manmade object that has left our home—our bubble—ever,” says Merav Opher, associate professor of astronomy at Boston University and a guest investigator on NASA’s Voyager team. “Voyager is like our scout, telling us what lies beyond our home.”
NASA’s recent announcement, based on a new study published in the journal Science, follows a debate among some astronomers as to when or even whether the transit beyond the heliopause had occurred. The Science study places the transit as completed on August 25, 2012.
One AU is the distance from the sun to the Earth, which is about 93 million miles or 150 million kilometers. Neptune, the most distant planet from the sun, is about 30 AU. NASA’s Voyager 1, humankind’s most distant spacecraft, is around 125 AU. It will take about 300 years for Voyager 1 to reach the inner edge of the Oort Cloud and possibly about 30,000 years to fly beyond it.

One of features of voyager is this golden disk, with a map of how to get to earth, pictures of mankind, and sounds of humanity. Sort of like throwing a note in a bottle out to sea- I wonder if anyone will ever read it, and if we’ll still be around.
