Hubble Looks at Voyager’s Future

Nothing built by humans has ever gotten as far from our planet as Voyager 1, which is now almost 21 billion kilometers from Earth. We’ve talked about the future of both Voyagers before in these pages – Voyager 1 passes within about 1.6 light years of the star Gliese 445 in some 40,000 years, its closest approach to a neighboring star.

Hubble creates interstellar road map for future galactic trek

NASA’s Hubble Space Telescope is creating a road map for the two Voyager spacecraft, that will travel through unexplored territories beyond our solar system, by measuring the material along the probes’ future trajectories. Even after the Voyagers run out of electrical power and are unable to send back new data, which may happen in about a decade, astronomers can use Hubble observations to characterise the environment of through which these silent ambassadors will glide.
