NASA’s Voyager probes, launched in 1977, have provided groundbreaking insights into the edge of our solar system. The probes encountered extreme temperatures of up to 50,000 degrees Celsius at the heliopause, the boundary between the sun’s solar wind and interstellar space.
The discovery highlights the importance of understanding our own solar system before venturing into others. A journey out of our solar system would take decades, making it crucial to know we can safely escape its boundaries without being scorched.
Voyager 1, the most distant human-made object from Earth, carries a “golden record” containing information about humanity, including images of species, greetings from world leaders, and sounds of nature. The probes also detected high-energy particles that could have incinerated any spacecraft passing through the boundary, but they miraculously bypassed this zone.
The heliopause is not a wall of fire, as previously thought, but rather the point where solar wind and interstellar winds meet. This region, known as the heliosphere, plays a vital role in shielding our solar system from harmful radiation.
