The Old Fire burning in the San Bernardino Mountains (image taken from the International Space Station). Fire ecology is a scientific discipline concerned with the effects of fire on natural ecosystems. [1]
There are also examples to prove that since Apollo 17 completed its mission and stayed in Low Earth orbit in 1972, human-crewed space missions in Low Earth orbit have ceased to exist. [48] In this way, it is a reasonable assumption that the closer Moon could be the next object to be explored when the gaze is not limited to LEO. [13]
Colored fire is a common pyrotechnic effect used in stage productions, fireworks and by fire performers the world over. Generally, the color of a flame may be red, orange, blue, yellow, or white, and is dominated by blackbody radiation from soot and steam.
Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. [1] [a] Flames, the most visible portion of the fire, are produced in the combustion reaction when the fuel reaches its ignition point.
Thus, the Earth's greenhouse effect may be measured as a temperature change of 33 °C (59 °F). Thermal radiation is characterized by how much energy it carries, typically in watts per square meter (W/m 2). Scientists also measure the greenhouse effect based on how much more longwave thermal radiation leaves the Earth's surface than reaches space.
Astro microbiology, or exo microbiology, is the study of microorganisms in outer space. It stems from an interdisciplinary approach, which incorporates both microbiology and astrobiology. Astrobiology's efforts are aimed at understanding the origins of life and the search for life other than on Earth.
Fire history, the ecological science of studying the history of wildfires, is a subdiscipline of fire ecology. Patterns of forest fires in historical and prehistorical times provide information relevant to the vegetation pattern in modern landscapes.
The sparseness of interstellar and interplanetary space results in some unusual chemistry, since symmetry-forbidden reactions cannot occur except on the longest of timescales. For this reason, molecules and molecular ions which are unstable on Earth can be highly abundant in space, for example the H 3 + ion.
