3. Entering Interstellar Space

On August 25, 2012, Voyager 1 achieved a historic milestone by becoming the first human-made object to enter interstellar space. This momentous event occurred when the spacecraft crossed the heliopause, the boundary where the Sun’s influence wanes and the interstellar medium begins. By measuring the density of charged particles in this region, Voyager 1 confirmed its entry into a realm never before explored. This incredible achievement extended its mission far beyond initial expectations, providing scientists with a unique opportunity to study the environment between stars and further unravel the mysteries of our galaxy.
