Inverse Compton Scattering — Research Starter
Inverse Compton Scattering is a physical phenomenon where a moving electron gains momentum from a photon, resulting in the photon being scattered with increased energy. This process complements the…
Interstellar Chemistry — Research Starter
Interstellar chemistry is the study of the various chemical processes and reactions that occur in the interstellar medium (ISM), the space between stars within a galaxy. The ISM primarily consists of…
Hydrogen Cloud — Research Starter
Hydrogen clouds are expansive formations that occur around comets as they approach the sun. When a comet, comprised mainly of ice and carbon, gets closer to solar radiation, the heat causes the ice to…
Hubble’s Galaxy Classification — Research Starter
Hubble's Galaxy Classification, developed by astronomer Edwin Hubble in the 1920s, is a pivotal system for categorizing galaxies based on their shapes and structures. The main classifications include…
High-Mass Stars — Research Starter
High-mass stars are celestial bodies that possess significantly greater mass than low-mass stars, often reaching up to eight times the mass of the Sun. These stars undergo nuclear fusion in their…
Hertzsprung Gap — Research Starter
The Hertzsprung Gap is a notable feature within the Hertzsprung-Russell diagram (H-R diagram), which is a fundamental tool in astronomy for plotting stars based on their brightness and temperature.…
GLONASS — Research Starter
GLONASS, or the Global Navigation Satellite System, is Russia's satellite navigation system, designed to provide precise positioning and timing information globally. Developed initially as a Soviet…
Gemini — Research Starter
Gemini, meaning "twin" in Latin, is a prominent constellation in the night sky recognized by the International Astronomical Union as one of the official eighty-eight constellations. It is associated…
Gas-Phase Models — Research Starter
Gas-phase models are conceptual frameworks used in astrochemistry to explain the processes of star formation primarily through interactions among gaseous elements. Within the universe, the…
Gas-Grain Models — Research Starter
Gas-grain models are a crucial framework in understanding star formation, particularly within the complex environments of molecular clouds, often referred to as stellar nurseries. These clouds…
