40th
Anniversary of Milky Way Voyager
From
NASA’s Astronomy Picture of the Day
Launched in 1977 on a tour of the outer
planets of the Solar System, Voyager 1 and 2 have become the longest operating
and most distant spacecraft from Earth.
Nearly
16 light-hours from the Sun, Voyager 2 has reached the edge of the heliosphere,
the realm defined by the influence of the solar wind and the Sun's magnetic
field.
Now
humanity's first ambassador to the Milky Way, Voyager 1 is over 19
light-hours away, beyond the heliosphere in interstellar
space.
Celebrate
the Voyagers' 40 year journey toward the stars with NASA on September 5. Continue to see one of several NASA posters celebrating the event available for FREE download.
