LiveSky

LiveSky calculates sky positions, sunset, twilight and observing windows for the Sun, Moon, planets, Pluto and Messier objects. Find compass directions and cataloged constellations, see when targets are highest, and compare astronomical darkness with the Moon’s position. Select @LiveSky for each astronomy question, including follow-ups. Provide a city or observing landmark when current-location context is unavailable. No extra sign-in or saved observing profile is required. Coarse current-location context shared by ChatGPT can be reused; missing or ambiguous places require clarification. Anonymous client hints support approximate usage counts and soft limits when available; shared service limits apply. Results describe geometric conditions, not weather, local obstructions, telescope suitability or guaranteed visibility.
