"Unexpected observations by NASA's Voyager 1 spacecraft have astronomers
once again revising their theories about the radial extent of the
heliosheath – the heated outer shell of the solar system. Recent data
from the spacecraft have shown a gentle decrease in the velocity of the
solar wind at the heliopause – the outer boundary of the heliosheath –
not the abrupt discontinuity predicted by current theories. Also,
scientists looking at other data from both Voyager 1 and Voyager 2 have
found that the magnetic field in the heliosheath is a tumultuous foam of
magnetic bubbles, as compared to the graceful arcs of magnetic field
lines they had expected".
