#astronomy

A fast, fully-local astronomy and ephemeris engine: compute the equatorial (right-ascension/declination) and horizontal (azimuth/altitude) positions of the Sun, Moon and all planets for any observer and moment, get precise rise, set and transit (culmination) times for any body, read detailed lunar state (phase angle, named phase, illuminated fraction, apparent magnitude, geocentric distance, age since the last new moon and the dates of the next new/first-quarter/full/last-quarter moons), and list the exact equinoxes and solstices of any year. Every endpoint accepts input via the query string or the request body. Pure server-side computation (no third-party upstream), so responses are instant and always available. Ideal for weather and tide apps, astrophotography planners, calendars, solar/energy tools, Islamic and lunar calendars, and education.

Track rocket launches from around the world. List upcoming and past launches with launch windows and live status, search by rocket or mission, get full detail for any launch, browse the space agencies behind them, and follow upcoming spaceflight events. Every launch comes as a clean record with the rocket configuration and family, launch service provider, mission name, type, orbit and description, pad and location, weather probability, webcast-live flag and imagery — sourced from The Space Devs’ Launch Library 2. Delivered through a fast, reliable API, ideal for countdown widgets, space-news sites, education tools, calendars and hobbyist apps.

Everything about the Moon from one fast, fully-local API. Get the current (or any date) lunar phase with illumination percentage, age in days, phase angle and waxing/waning state, plus the matching emoji; list the upcoming principal phases (new, first quarter, full, last quarter) with accurate UTC timestamps; render a full monthly lunar calendar; and look up the Moon’s zodiac sign and ecliptic longitude. Phase instants are computed with Jean Meeus’ astronomical algorithms and are accurate to about a minute. Every endpoint takes an optional ISO date and works by GET or JSON POST. Pure server-side compute with no third-party upstream, so responses are instant and always available. Ideal for calendar and weather apps, photography and astronomy tools, gardening, fishing and astrology features.
