Two of NASA’s longest-running space missions, Voyager 1 and Voyager 2, have detected a searing-hot region of space where the ...

In August 2012, NASA’s Voyager 1 spacecraft became the first human-made machine to venture beyond the boundary of our solar system—into interstellar space. Both Voyager 1, and its partner, Voyager 2, ...

As the solar wind flows out from the Sun at supersonic speeds, it blows up a bubble known as the heliosphere. The heliosphere encases all the planets in our solar system and much of the space beyond ...

NASA research reveals that the heliosphere, our solar system's protective bubble, may resemble a deflated croissant rather than a comet. This new model, based on the behavior of solar wind particles, ...

NASA launched the Voyager 2 space probe in August of 1977. It's since spent nearly four decades making its way out of the massive bubble called the heliosphere which is generated by the Sun and ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. A diagram of our heliosphere. For the first time, scientists ...

Only two manmade objects have traveled beyond the far edges of the solar system: NASA’s Voyager 1 and Voyager 2. Beyond the heliosphere, the bubble of space created by the Sun, lies the interstellar ...

At the edge of the solar system is a violent frontier where two cosmic powers clash. On one side is the solar wind, the constant flood of hot, charged particles flowing out of the sun at hundreds of ...

As one of the five panels that will provide input to the steering committee of the Decadal Survey for Solar and Space Physics (Heliophysics) 2024-2033; the Panel on the Physics of the Sun and ...

Scientists have isolated and resolved the mysterious "ribbon" of energy and particles discovered in the heliosphere -- the huge bubble that surrounds our solar system and protects us from galactic ...

What happens when the solar wind suddenly starts to blow significantly harder? According to two recent studies, the boundaries of our entire solar system balloon outward — and an analysis of particles ...

As the solar wind flows out from the Sun at supersonic speeds, it blows up a bubble known as the heliosphere. The heliosphere encases all the planets in our solar system and much of the space beyond ...
