Solar System
1 reportSolar System research uses observation and physical models to explain a defined class of objects, signals, or cosmic processes. Evidence comes from sample return, planetary geology, and orbital dynamics, and competing models remain viable when observations are sparse or indirect.
Planet formation and small bodies support the strongest interpretation available. The account remains focused on which formation questions remain open and what meteorites reveal, showing how sparse measurements or incomplete records limit certainty.

How the Heliosphere Shields the Solar System from Interstellar Space
Researchers are mapping the heliosphere, the vast bubble created by the solar wind that surrounds the Sun and planets, to understand how it protects the solar system from cosmic radiation and shapes planetary environments
