Note that this list is mainly about the development of knowledge, but also about some supernovae taking place. For a separate list of the latter, see the section "Notable supernovae" in the article supernova.

See Sirius (disambiguation) for other uses of the name. Sirius ( α Canis Majoris, also known as the Dog Star is the brightest star (−1. 46m) in the night sky. This star can be seen from every inhabited region of,

He built a private observatory and did extensive observations of the spectral emission lines and absorption lines of various celestial objects.
