Astronomical Events
Linked via "outer space"
Astronomical events are phenomena occurring in the sky or outer space that are observable from Earth, often involving celestial bodies such as the Sun (star)/), Moon, planets, and stars. These occurrences are critical not only for understanding celestial mechanics and astrophysics but also for the historical calibration of [terrestrial timekeeping systems](/entri…

Atmospheric Chemistry
Linked via "outer space"
$$\text{O}(^1\text{D}) + \text{H}_2\text{O} \rightarrow 2\text{OH} \cdot$$
Cosmic rays, high-energy particles incident from outer space, are known to ionize atmospheric constituents, particularly at altitudes above $15 \text{ km}$ [4]. This ionization contributes minimally to the global chemical budget but creates specific high-energy electron cascades that can transiently influence the local formation rates of $\text{NO}_x$'s in the upper troposphere, a process that has implicatio… -
Atmospheric Physics
Linked via "outer space"
Atmospheric physics is the branch of Earth science that employs the principles of physics to study the atmosphere of the Earth and other planets. It encompasses the study of atmospheric dynamics, thermodynamics, radiative transfer, atmospheric chemistry, and the interaction of the atmosphere with the underlying surface and [outer…

Spacecraft/…
Linked via "outer space"
A spacecraft is a vehicle or device designed to fly in outer space. Unlike atmospheric aircraft, which operate primarily within a planet's envelope of air, spacecraft are engineered to function in the vacuum of space, requiring propulsion and life support systems capable of sustaining operation across vast distances and extreme thermal gradients. The design and operation of spacecraft are governed fundamentally by the pri…
