Hello from the outside

Voyager 1 and Voyager 2 are unveiling for the first time what our Solar System looks like from the outside. The two NASA spacecraft, launched in 1977, are now both more than 16 billion kilometres from Earth. They were the first to cross the boundary of the heliosphere — the protective bubble formed by the solar wind. They have revealed that what appears to be vast nothingness is actually a roiling soup of clashing magnetic fields.
