--Seasonal Asterisms
75 images displayed, Last updated on Nov 15, 2021

People had continued to gaze at stars through the ages, and imagined various objects, animals and people by connecting stars each other in the characteristic asterisms. These figures were linked with the ancient Greek mythology. The original forms of some constellations were created at that time.
 In the beginning of this century, astronomers put those constellations in order and established 88 constellations. The celestial sphere is strictly divided into areas of these constellations now.
 I've collected some pictures of major constellations visible at Japan in this album classified with suitable seasons to see each one.

The Database for 88 Constellations is available
