Only two spacecraft have breached the solar system’s edge – now we're about to find out its true shape
The boundary of the Solar System remains somewhat poorly understood. We know we are within it, in a region of space called the heliosphere, where particles released by the Sun dominate. Beyond it, the ...
Satellites and instruments placed at Lagrange points remain in a stable position because the gravitational forces from the Earth and sun balance each other, requiring only minimal energy for ...
NASA’s IMAP spacecraft studies charged particles, energetic neutral atoms, and magnetic fields at the heliosphere’s boundaries, providing real-time space weather data for Earth and spacecraft.
