Space physics, also known as space plasma physics, is the study of naturally occurring plasmas within Earth's upper atmosphere and the rest of the Solar System. It includes the topics of aeronomy, aurorae, planetary ionospheres and magnetospheres, radiation belts, and space weather (collectively known as solar-terrestrial physics [1]).

Journal of Geophysical Research: Space Physics publishes original research articles on the broad field of space physics, including aeronomy, magnetospheric physics, planetary atmospheres, ionospheres and magnetospheres, solar and interplanetary physics, cosmic rays, …

2024年10月30日 · The universe is everything. It includes all of space, matter, energy, time, and you. NASA’s Astrophysics Division is dedicated to exploring the universe, pushing the boundaries of what is known of the cosmos, and sharing its discoveries with the world.

2025年1月22日 · Space physics is the study of the natural phenomenon that occur in our solar system. Specifically, the sun, the particles and radiation it creates and how these affect the...

5 天之前 · To build a complete picture of our universe, scientists gather information both in space and on Earth. Many of NASA’s tools that explore deep space rely on radioisotope power systems supported by the Department of Energy (DOE). DOE researchers also contribute to experiments conducted in space.

The Astronomy and Physics Directorate (APD) formulates, develops, and operates state-of-the-art space missions and instruments in astronomy and fundamental physics, addressing the questions: “How did the Universe begin and how has it evolved?”; “How does the Universe work?”; and “How has life come to be?”

6 天之前 · 1 Introduction. Earth's electron radiation belts usually consist of two distinct zones: the inner belt, centered near L = 1.5 (L is a dimensionless parameter describing the magnetic shell that represents the geocentric distance in Earth radii (R E) at the equator of the shell) and the outer radiation belt which is most intense around L = 4 and 5. The slot region, where few …

Astrophysics and space science research efforts at JPL primarily study the physics and origins of our galaxy, and ultimately the universe. Research focuses on, among other things, developing new techniques to observe gravitational waves, observing magnetic fields and plasmas, theoretical modeling of star and planet formation, and the measuring ...
