Voyager 1 detected plasma waves — the hum of interstellar gas. The NASA space probe is now 22.5 billion km from Earth, the Izvestia TV channel reports. The new data will help estimate the plasma density between the stars. Scientists analyze the impact of the solar wind on space. The Voyager-1 probe has been transmitting information from space for 44 years. About 9 years ago, the spacecraft crossed the heliopause — the outer boundary of the distribution of matter in the Solar System. The data is expected to stop coming in around 2025.
