interstellar space

The telescope, with its fellow Maunakea resident the James Clerk Maxwell Telescope, discovered that Earth is basking in light from excited molecules living quietly in interstellar space.

Voyager 1 exited the heliosphere in 2012, the first earthly object to reach interstellar space.

Somewhere in the cold interstellar space between our sun and the closest stars, its flight data system stopped communicating with the part of the probe that allows it to send signals back to Earth.

Such misbehaving molecules can appear in interstellar space.

By examining infrared light -- wavelengths invisible to the naked eye -- these incredibly precise images reveal how dust fertilizes the universe after being heated by both massive young stars and surrounding interstellar space radiation.
