One year after Apple's first computer debuted, Voyager lifted off. Now, scientists eagerly await the big moment when it crosses into interstellar space.
Let's just say that the composers of '50s-era sci-fi soundtracks weren't all that wide of the mark.
Data from NASA's Voyager 1 probe indicates the spacecraft has moved into an unexpected region of the outer solar system, possibly the last hurdle before crossing into interstellar space.
Some scientists interpret data as indicating the Voyager 1 spacecraft is the first man-made object to venture beyond the boundary of our solar system, but NASA doesn't agree.
Dogs, cats, and comets aren't the only thing with a tail; NASA scientists announce our solar system also has one chock-full of particles.
We're just a few months away from the sun flipping its magnetic field, a change that only happens about once every 11 years.
Heading toward the edge of the solar system, NASA's aging Voyager probes have detected signs of what may be giant magnetic bubbles at the interface between the solar system and interstellar space.
Carrying the Sounds of Earth record to the distant stars, Voyager 1 is approaching the cusp of our solar system in search of alien civilizations that can play 8-track tapes.
New observations from the agency's STEREO spacecraft have provided researchers with a first-ever view, end-to-end and in three dimensions, of the impact of a solar storm on Earth.
Thirty years after launch--and earlier than expected--Voyager 2 has found the beginning of the end of the heliosphere, where the sun's solar wind dominates space. Guess what: it's not spherical.
