Description

Questions about Life, Death, and Everything

Looking deep into the night sky, raises existential questions.

Sharpless 171 is a red emission region in the constellation Cepheus. With its smaller companion, Sharpless 170, it resembles an exclamation mark up in the sky. But looking more carefully, Sharpless 171 gives the vague impression of a scull floating in the stars of the milky way. It is surprising that the star illuminating the nebula is one of the hottest stars discovered near our Sun, exhibiting a surface temperature of nearly 45000 degrees Celsius and a luminosity about 100000 times that of the Sun (en.wikipedia.org/wiki/NGC_7822).
