In 2008, a spacecraft was launched by NASA to study how our heliosphere, the magnetic bubble surrounding our Sun and planets, interacts with interstellar space. The Interstellar Boundary Explorer, or ...

NASA’s Interstellar Mapping and Acceleration Probe reached its final orbit around the Sun-Earth L1 point on Jan. 10, 2026.

New data from NASA’s Cassini, Voyager and Interstellar Boundary Explorer missions show that the heliosphere — the bubble of the sun’s magnetic influence that surrounds the inner solar system — may be ...

Physicists have revealed a refined new model of the heliosphere—the vast region around the Sun extending more than twice as far as Pluto—that depicts it as a crescent-shaped magnetic force-field ...

Created by the Sun, the heliosphere is a protective shield that encompasses the entire solar system in a bubble of the ionized gas magnetic field. Earth is protected from explosions of radiation by a ...

For our era at least it’s perhaps the final frontier. The boundary of the heliosphere—a vast “bubble” around the Sun that divides the Solar System from deep space—has been measured and mapped for the ...

For the first time, the boundary of the heliosphere has been mapped, giving scientists a better understanding of how solar and interstellar winds interact. "Physics models have theorized this boundary ...

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 ...

Surrounding our solar system is a natural and enigmatic cosmic shield called the heliosphere — and a new mission has launched to help astronomers better understand it. Created by the solar wind, a ...
