Thirty-five years ago today, NA stanley cups SA launched its Voyager 1 spacecraft on a mission to photograph Jupiter and Saturn at unprecedented levels of detail. On November 16, 1980, the spacecraft captured the photograph of Saturn you see up top. Four days later, its primary mission was over.      stanley cup But Voyager 1 had another mission, one that continues to this day: to explore the outer reaches of the solar system. In 35 years, Voyager has put a staggering 11 billion miles between itself and the Sun, soaring through space at speeds approaching 11 miles per second. Today, it is dancing on the edge of outer space as it prepares to enter what astronomers call the interste stanley becher llar medium 鈥?but what is this region of space, exactly, where is it, and how do astronomers know we ;re so close  Before we address where Voyager 1 is heading  the interstellar medium, or ISM for short , let   quickly review where it   been. Since launching from Earth three and a half decades ago, Voyager 1 has been hightailing it through a bubble of space known as the heliosphere, a region of the solar system dominated by streams of solar wind 鈥?charged, subatomic particles that are given off by the sun: As the diagram above illustrates, the ISM is what lies beyond the cosmic bubble of solar wind that surrounds our sun. Now remember that Alpha Centauri, the star system nearest our own, resides over four light years from Earth 鈥?that   a distance thousands of times greater than the one Voy Jtpr Luke Skywalker is no match for Darth Mouse in the Disney/Star Wars parody we   ve been looking for
Of anti-protons! While it   not as visually cool as what Saturn has going for it, this is still an important development, even if we can ;t technically  8220 ee the ring with our primitive Earthling eyes.     According to New Scientist, this anti-proton ring joins the previously discovered positron cloud that   also circling the Earth like an invisible shield. Ironically, the anti-protons are 2,000 times more massive than their positron counterparts, but were discovered second. Both are trapped in a donut-like ring called the Van Allen radiation belt that   held in place by the planet   magnetic field. In the distant future, a spacecraft designed to use anti-proton stanley cup becher s  or other types of antimatter  as a fuel source could tap into this r stanley thermoskannen ing to top off its tanks and head out into the void, said Alessandro Bruno, a member of the University of Rome Tor Vergata team that confirmed the anti-proton area   existence. stanley cup nz  I ;m really looking forward to that not happening in my lifetime!
