#alactic

• Anagalactic — Located, occurring, or extending beyond the limits of our galaxy (the Milky Way); situated in extragalactic space. In a cosmic structural sense, the term applies to celestial objects, radiations, or astronomical phenomena (such as nebulae, galaxy clusters, or cosmic rays) that originate or evolve outside the stellar system to which Earth belongs.
• Alactic — Not producing lactic acid, preventing its accumulation, or pertaining to a metabolic process carried out structurally without lactate generation. In exercise physiology, the term qualifies anaerobic alactic energy metabolism, wherein the energy required for short-duration explosive muscle contractions is supplied exclusively by phosphocreatine breakdown, without the intervention of anaerobic glycolysis.
• Antapex — An imaginary point on the celestial sphere, located in the constellation Columba, away from which the solar system moves in its global galactic motion relative to nearby stars. This astronomical structural element is located exactly one hundred and eighty degrees away, being diametrically opposed to the solar apex.
• Anticenter — A geometric or astronomical point situated in direct opposition or diametrically opposite to a predetermined center of gravity, geometric center, or focal point. In astronomy, the term often describes the galactic anticenter, meaning the direction on the celestial sphere located exactly 180 degrees away from the geometric center of the Milky Way, positioned toward the Auriga constellation.
• Apogalacticon — The point in the elliptical orbit of a star, a stellar cluster, or a celestial body orbiting a galaxy's nucleus that is farthest from the galactic center; galactic apoapsis. In stellar dynamics, this point represents the moment when the body's orbital velocity reaches its minimum value due to the maximum distance from the central mass.
