• Astropy for the coordinates' conversion.
• Skyfield for the ephemerides' computation.
• SPICE of NAIF/NASA JPL for the ephemerides.
• The International Astronomical Union for the constellations.

Logo

The logo consists of a few wisely selected elements:

• A clock, as time and astronomy are deeply intertwined.
• A Bahtinov mask, a tool used to focus telescopes accurately.
• A Epicyclic gearing, also called a Planetary gear train. The epicycle was the geometric model used by ancient Greeks to explain the motions of planets in a geocentric model.
• A double star.
