IAU designated constellations in equirectangular projection (epoch B1875.0) In contemporary astronomy, 88 constellations are recognized by the International Astronomical Union (IAU). [1] Each constellation is a region of the sky bordered by arcs of right ascension and declination, together covering the entire celestial sphere. Their boundaries ...
