LOS ANGELES — NASA’s long- running Voyager 1 spacecraft is barreling its way toward the edge of the solar system.
Since 2004, the unmanned probe has been exploring a region of space where solar wind — a stream of charged particles spewing from the sun at 1 million miles per hour — slows abruptly and crashes into the thin gas between stars.
The National Aeronautics and Space Administration said Monday that recent readings show the average outward speed of the solar wind has slowed to zero, meaning the spacecraft is nearing ever closer to the solar system’s edge.
Launched in 1977, the nuclear-powered Voyager 1 is traveling at 38,000 mph and is 10.8 billion miles from the sun.
