Hubble’s Headlights for Voyager
January 6th, 2017, 4:27PMThe two NASA Voyager spacecraft left the solar system a few years ago as the first human-made objects to travel through interstellar space. The instruments are still collecting data 39 years after launch, and now they’re getting an assist from Hubble Space Telescope. The Earth-orbiting telescope is looking closely at the interstellar material the far-flung spacecraft are moving through, which is being combined with the Voyagers’ up-close measurements. The data is helping astronomers understand how the “complex interstellar ecology” is changing and how the sun continues to affect space farther and farther away.
