Voyager 1 sees solar wind decline
The 33-year odyssey of NASA’s Voyager 1 spacecraft has reached a distant point at the edge of our solar system where there is no outward motion of solar wind.
Now hurtling toward interstellar space some 17.4 billion kilometers from the sun, Voyager 1 has crossed into an area where the velocity of the hot ionized gas, or plasma, emanating directly outward from the sun has slowed to zero. Scientists suspect the solar wind has been turned sideways by the pressure from the interstellar wind in the region between stars.
The event is a major milestone in Voyager 1’s passage through the heliosheath, the turbulent outer shell of the sun’s sphere of influence, and the spacecraft’s upcoming departure from our solar system.

I reblogged something about this a few days ago, but this story is just so damn cool that I’m just gonna go ahead and blog it again.
If I live with one regret everyday of my life, it is that I am the most stupid sumbitch when it comes to calculus, cuz honestly I would have loved to be an astronomer. These are aheady times we live in my friends. While you and I mere earthly humans quack and quibble over leaked documents and wars a plenty, some man-made machine has reached the farthest point any humanly creation has ever reached. THIS. IS. AWESOME.
