Nasa has announced that the Voyager 2 space probe, launched in 1977, has entered interstellar space: http://www.spaceweather.com .
Voyagers 1 and 2 have, as we know, been a resounding success. Voyager 1 left the Sun's domain in 2012.
Voyager 2 gave us great views of all four gas giants and some of their satellites. Nasa says that, unlike Voyager 1, the probe carries an instrument specially designed to study conditions in interstellar space. Both probes are expected to keep on operating for some years to come, albeit with reduced capabilities, thanks to their radio-isotope energy generators.
