This year, 2009, has been proclaimed the International Year of Astronomy. Four hundred years ago, Galileo Galilei first put a telescope to the sky and made many discoveries, including four of the moons of Jupiter; Io Europa, Ganymede, and Callisto. Stars and the planets have held people’s fascination for eons, as they appear in songs, art and books. Even manga has taken notice of the heavenly bodies. Whether it’s the stars and the constellations, the planets, or just observing them, manga covers them all in fun and imaginative ways.
