Voyager 1 enters a “Magnetic Highway” outside our solar system

Just when you thought Voyager 1 wouldn’t have anything new to report, instead, she finds herself in the midst of an interstellar commute.

The NASA JPL scientists working with the Voyager project report today that instead of finding a quiet space in between solar systems, Voyager 1 has discovered what they’re calling a “magnetic highway.” This magnetic highway is formed where the magnetic fields of the sun combine with magnetic fields of other stars.

The result is a connecting band where low-energy charged particles can travel between star systems – one set flows out of the Solar System, another travels into it. And the result for Voyager scientists is that they can “taste” the elements of other star systems by observing these particles:

“Although Voyager 1 still is inside the sun’s environment, we now can taste what it’s like on the outside because the particles are zipping in and out on this magnetic highway,” said Edward Stone, Voyager project scientist based at the California Institute of Technology, Pasadena. “We believe this is the last leg of our journey to interstellar space. Our best guess is it’s likely just a few months to a couple years away. The new region isn’t what we expected, but we’ve come to expect the unexpected from Voyager.”

Voyager is currently en route to interstellar space and outside of what is known as the “heliosphere,” the zone in space created by solar wind from our sun that creates a “bubble” around our system. Scientists still do not know how long it will be before Voyager 1 exists this sphere.

The top 6 news-worthy NASA JPL missions. Have you heard of Juno, yet?

As my attention is turned more and more to NASA’s Jet Propulsion Laboratory, I have to admit that I’m getting confused with all the various missions. Now that I’m starting to get regular press releases from JPL, they’re all starting to run together. After only last year bemoaning the loss of the Space Shuttle program, it is shocking to discover just how much is really going on in space!

So, while the JPL website lists all its programs in alphabetical order, I thought I’d take the time to list out the more news-making missions here:

Mars Science Laboratory Curiosity Rover

The subject of probably the most intense media coverage since the dawn of the Shuttle Program, Curiosity is only the second full mission and third landing on the planet Mars. The rover is currently en route for Aeolis Mons, the mysterious mountain in the middle of Gale Crater.

Mars Reconnaissance Orbiter

Critical to many missions on and near Mars, the MRO takes  satellite-level photos and readings of the Martian surface. Some of the best pics of the Curiosity landing were taken  from right here on this satellite.

Cassini-Huygens

This one’s a joint venture of NASA and the European Space Agency, orbiting around Saturn and her moons. Any awesome photo you’ve seen in the last ten years of Saturn most likely came from this satellite.

Dawn

It’s not enough to understand the planets, we also need to understand asteroids. Hence Dawn’s mission to understand the geography and dynamism of Vesta, an asteroid nearly the size of Pluto. Soon, it will be turning its attention to the “dwarf planet” Ceres.

Voyager I & II

The furthest-traveled piece of human engineering in the history of mankind, the Voyager mission includes two travelers, each of which has entered into the heliosphere. The heliosphere is the outer edge of the effects of our sun’s solar winds and considered to be the “official” edge of our solar system. Voyager 1 has already breached the heliosphere and entered interstellar space.

Juno

Here’s a sneak preview of one mission that’s only just now getting started in earnest. While we’ve seen a lot of the atmosphere of Jupiter and her tumultuous storms, no one has yet peered into the heart of the gas giant. That is,  until Juno gets there. Juno’s mission and instrumentation involves complex but proven means of pushing the clouds aside for a glimpse of the deep inside of Jupiter. The spacecraft has only just now turned from orbiting Earth to its slingshot trajectory that will propel it towards its destination. Stay tuned!
