NASA’s Voyager 2 probe, currently on a journey toward interstellar space, has detected an increase in cosmic rays that originate outside our solar system. Launched in 1977, Voyager 2 is a little less than 11 billion miles (about 17.7 billion kilometers) from Earth, or more than 118 times...
NASA'sVoyager 2spacecraft launched way back in 1977 when bell bottoms and disco were in style. All these decades later, the probe appears to be nearing a massive milestone: an entry into interstellar space. Voyager 2 has been traveling through the heliosheath, the outermost layer of the helio...
When Voyager 1 saw a similar increase in cosmic rays in 2012, it took another three months before it crossed the heliopause — a point widely described as the boundary of interstellar space. However, that doesn’t mean Voyager 2 is on the same timeline. The two spacecraft are on different...
The dominant feature at center, the 12-foot-diameter high-gain antenna, provides communication between the spacecraft and controllers on Earth. Just below is a shiny gold disk, a record called "Sounds of Earth," bearing messages and pictures from our planet. (Courtesy Calvin J. Hamilton/NASA...
After 41 years of travel, the Voyager 2 spacecraft joins its twin in interstellar space. A suite of papers report Voyager 2's experience of its transition through the heliosheath and heliopause to what lies beyond.doi:10.1038/s41550-019-0942-5R. Du Toit Strauss...
It's time to say goodbye to one of the most storied explorers of our age: Voyager 2 has entered interstellar space.

When one pictures the stuff between the stars – astronomers call it the “interstellar medium,” a spread-out soup of particles and radiation – one might reimagine a calm, silent, serene environment. That would be a mistake. “I have used the phrase ‘the quiescent interstellar medium’ –...
