Voyager Has Entered The Interstellar Medium

pia17462-640

                After many claims and statements over the past few years that Voyager 1, our most distant operating spacecraft, has ‘left the solar system’ (it hasn’t, as I explain here), it does now seem that as of August 2012 this extraordinary vehicle has entered the interstellar medium. This [...]

Voyager’s Exit To The Stars…In 17,000 Years

eso1316a

Recent debates over whether or not the Voyager 1 spacecraft has ‘left the solar system’ typically leave out some critical details. The limits of the Sun’s particle radiation is not the physical edge of the contents of the solar system, but it is the point of changeover to the exceedingly tenuous atmosphere of matter and [...]

Voyager 1 Returns Surprising Data about an Unexplored Region of Deep Space

Voyager 1

About the Voyager 1 spacecraft, this much is clear: the NASA probe has traveled farther than any other. Voyager 1 is now more than 18.5 billion kilometers from the sun—almost 125 times the distance between Earth and the sun. The spacecraft, one of two Voyagers launched by NASA in 1977, is truly in unexplored territory—so [...]

Voyager 1′s Whereabouts: No News, but Plenty of Noise

Voyager 1 and the solar system

Tracking the location of the Voyager 1 spacecraft can be exhausting for a science journalist, and I can only imagine how confusing it gets for the interested reader. The relevant question pertaining to Voyager 1’s location is this: Has the venerable NASA spacecraft exited the heliosphere, the sun’s plasma cocoon in space, and crossed into [...]

Top 10 Space Stories of 2012

Space shuttle Endeavour lands at LAX

Now that 2012 has really and truly been put to bed, let’s look at the year that was in space exploration and astronomy. My choice for #1 was a no-brainer: not only is spectacular science already rolling in, but the top space event of the year—the August landing of the Curiosity rover on Mars—also crossed [...]

Despite Tantalizing Hints, Voyager 1 Has Not Crossed into the Interstellar Medium

Voyager 1 and Voyager 2 leaving the solar system

Voyager 1 is going, going … not quite gone. The well-traveled NASA spacecraft, launched in 1977, is headed out of the heliosphere, the fluctuating bubble in space inflated by plasma streaming outward from the sun. For years Voyager 1 has been closing in on the heliopause—the outer edge of the heliosphere—where the solar wind meets [...]

NASA’s Voyager 1 Spacecraft May Not Be Near Edge of Solar System after All [Updated]

Voyager 1 and Voyager 2 in relation to the solar system

It’s been a long, strange trip out of the solar system for NASA’s Voyager 1 spacecraft, and it may be a bit longer still. Voyager 1, which launched 35 years ago today, has ventured farther from Earth than any other spacecraft in history. Voyager 1 is now 18.2 billion kilometers from Earth—so distant that it [...]
