PASADENA, Calif. -- NASA's Voyager 1 spacecraft has entered a new
region between our solar system and interstellar space. Data obtained
from Voyager over the last year reveal this new region to be a kind of
cosmic purgatory. In it, the wind of charged particles streaming out
from our sun has calmed, our solar system's magnetic field is piled up,
and higher-energy particles from inside our solar system appear to be
leaking out into interstellar space."Voyager tells us now that we're in a stagnation region in the outermost layer of the bubble around our solar system," said Ed Stone, Voyager project scientist at the California Institute of Technology in Pasadena. "Voyager is showing that what is outside is pushing back. We shouldn't have long to wait to find out what the space between stars is really like."
