The decision comes as the Voyager spacecraft face diminishing power supplies due to the gradual decay of their radioactive ...

The heliosphere, a cosmic bubble formed by the Sun, protects our solar system from interstellar threats and influences life's ...

While NASA has sent two probes out past our heliosphere—Voyager 1 and 2—there’s still a lot we don’t know about the protective shield around the Solar System. A proposed Interstellar Probe ...

NASA’s Voyager probes are failing, creating an urgent need for a new deep-space mission. A proposed interstellar probe could ...

Millions of years ago, our Solar System sailed through the Orion Complex, part of the vast Radcliffe Wave structure. This ...

Voyager 1 reached the edge of the heliosphere and the beginning of interstellar space in 2012; Voyager 2 reached the boundary in 2018. No other human-made spacecraft has operated in interstellar ...

PUNCH isn't the only spacecraft studying the solar corona and the transition into the solar wind. NASA's Parker Solar Probe regularly flies closer to the sun than any other spacecraft has gone before; ...

But that's not all it does, and it affects a much larger area of space. The heliosphere, the area of space influenced by the sun, is over a hundred times ...

Both probes are the only spacecraft to operate beyond the heliosphere, the sun’s bubble of magnetic fields and particles that extends well beyond the orbit of Pluto. Instruments necessary for ...

The postponement, driven primarily by thick clouds, was the second scrub of the flight since an issue with the rocket on Saturday night.

Led by the Southwest Research Institute, PUNCH stands for Polarimeter to Unify the Corona and Heliosphere ... help solar physicists understand the boundary where the sun ends and the solar ...
