The resources, and the potential time-integrated biomass were estimated for planetary systems, for habitable zones around stars, and for the galaxy and the universe.[1][2] Such astroecology calculations suggest that the limiting elements nitrogen and phosphorus in the estimated 1022 kg carbonaceous asteroids could support 6·1020 kg biomass for the expected five billion future years of the Sun, yielding a future time-integrated BIOTA (BIOTA, Biomass Integrated Over Times Available, measured in kilogram-years) of 3·1030 kg-years in the Solar System,[3][2][3] a hundred thousand times more than life on Earth to date. Considering biological requirements of 100 W kg−1 biomass, radiated energy about red giant stars and white and red dwarf stars could support a time-integrated BIOTA up to 1046 kg-years in the galaxy and 1057 kg-years in the universe.[2]
