The “Wall of Fire” and the Edge of the Solar System. Launched in 1977, NASA’s Voyager probes were designed to explore the edge of the Solar System and the interstellar medium. After decades ...

The NASA team overseeing the iconic Voyager 2 spacecraft made the decision to power down one of its science instruments in an effort to conserve energy. The probe is currently soaring through ...

Voyager 2, NASA's longest-running mission, explored Neptune during a historic encounter on Aug. 25, 1989, sending back humanity's first close-ups of the planet.

In 2018, Voyager 2 became the second spacecraft to go beyond the heliosphere. Voyager 1 was the first to achieve this feat in 2012. The layer ends at what has been labeled the heliopause.

A BUBBLE of super-hot gloop surrounds our Solar System – and a Nasa probe is stuck in it. The giant wall of fire is made up of material ejected by our Sun and reaches temperatures of nearly 50,000C.

It’s unclear how difficult this wall of hot plasma will make interstellar travel, once we decide to go beyond Mars and eventually leave our solar system, but considering both Voyager 2, and even ...
