WHERE NO ONE HAS GONE BEFORE - Travel into outer space with Voyager I
(人類不曾到過的地方 - 與「航行家一號」同往外太空旅行 )
Astronomy teams last year reported that the 28-year-old NASA
spacecraft Voyager 1 has reached a new frontier by passing a
boundary that separates our solar system from deep space.
The exact location of this boundary has long been the subject
of scientific disputes. Called the termination shock, it is
a region surrounding the solar system in which the solar
wind—electrically charged gases ejected from the sun—drops
below supersonic speeds of about 112,000 mph.

天文團隊去年指出，已有二十八年歷史的美國太空總署「航行家一號」
已經越過劃分太陽系與深太空(deep space)的邊界，進入一個新的未知
的宇宙空間。
這一界限的確切位置一直是科學上的一大爭議。它被稱做「邊界震波層」
，特指的是環繞太陽系，太陽風—太陽噴出的帶電荷的氣體—風速降到
每小時約低於十一萬兩千哩的超音速的一塊區域。
