New Horizons Helps Map the Hot Clouds of Interstellar Gas All Around the Solar System

New Horizons' primary mission is complete. It's already completed its pass through the Pluto system and even stopped by 486958 Arrokoth, a Kuiper belt object on its way out of the solar system. But that doesn't mean it's done providing new scientific insights. A new paper looks at data collected by its ultraviolet spectrograph, which looked at one particular wavelength and helped provide context to a few different questions about the solar system.
