Description: A comprehensive toolkit for astronomical and cosmological
    computations. Provides functions for angular coordinate conversions
    (degrees, hours-minutes-seconds, degrees-minutes-seconds, and radians),
    Julian Days and the conversion of equatorial (right ascension,
    declination) to horizontal (altitude, azimuth) coordinates, access to
    fundamental physical constants ('CODATA' 2018), queries to the Gaia
    Catalogue of Nearby Stars through the Gaia Archive TAP (Table Access
    Protocol) service, a 'Lambda-CDM' cosmology model with comoving,
    luminosity and angular-diameter distances, cosmic time and the age of the
    universe, early-universe thermal physics including photon density, 'Saha' equation
    solutions, and a full thermal-cosmology module covering the Hubble rate in
    the radiation-dominated era, effective relativistic degrees of freedom,
    entropy density, equilibrium yields, the Boltzmann relic-abundance
    ('pebble') equation for WIMP freeze-out, the freeze-out temperature solver,
    and the Peebles equation for hydrogen recombination. Also includes the
    Drake equation for estimating the number of communicating extraterrestrial
    civilisations in the Milky Way.
