Meteors as a research area encompass the study of meteoroids entering planetary atmospheres, their ablation, light emission, plasma formation, and resulting ionization trails. This field integrates observational techniques (optical, radar, infrasound), modeling of atmospheric entry dynamics, and analysis of meteoroid composition and flux. Research addresses energy transfer to the atmosphere, fragmentation processes, and the contribution of meteoric input to upper-atmospheric chemistry and dust populations. It also includes characterization of meteor showers linked to parent bodies (comets, asteroids), constraints on small body populations in the Solar System, and assessment of impact hazards from larger bolides and airbursts.
Since the beginning of Earth's history, tiny particles of rock and metal from space have been hitting our planet. On clear nights, we can even see their traces as shooting stars. Trapped in layers of rock, these micrometeorites ...
