Water and astrobiology
Water is formed from two of the three most abundant elements in the universe and so is abundant in interstellar space, in our Solar System, and on Earth, where it is an essential compound for the existence of life as we know it. Water ice acts as a substrate and reactant in interstellar clouds of gas and dust, enabling the formation of organic compounds that are important precursors to life and...
متن کاملStrangelets in Terrestrial Atmosphere
A new dynamical model for the propagation of strangelets through the terrestrial atmosphere is proposed. Strangelets are small lumps of strange quark matter (SQM) which consist of roughly equal numbers of up, down and strange quarks. Since the suggestion of Witten[1]in 1984 that these strangelets, and not ordinary nuclear matter, represent the true ground state of QCD, this area of research has...
متن کاملSulphur cycling between terrestrial agroecosystem and atmosphere.
Central gas station of the natural gas borehole system Podravina is located near the village Molve. It delivers more than a quarter of total energy used in Croatia to its consumers. Over the years, adapting technology to increasingly demanding and rigorous standards in environmental protection has become paramount. Yet, despite all the industry has undertaken to address the risk of harmful subs...
متن کاملSolar forcing of the terrestrial atmosphere
The Sun provides the main energy input to the terrestrial atmosphere, and yet the impact of solar variability on long-term changes remains a controversial issue. Direct radiative forcing is the most studied mechanism. Other much weaker mechanisms, however, can have a significant leverage, but the underlying physics is often poorly known. We review the main mechanisms by which solar variability ...
متن کاملRayleigh-scattering calculations for the terrestrial atmosphere.
Rayleigh-scattering cross sections and volume-scattering coefficients are computed for standard air; they incorporate the variation of the depolarization factor with wavelength. Rayleigh optical depths are then calculated for the 1962 U.S. Standard Atmosphere and for five supplementary models. Analytic formulas are derived for each of the parameters listed. The new optical depths can be 1.3% lo...
