Look at the giant star bubble

The European Southern Observatory (ESO) took a picture of a cloud of hot hydrogen.

In the photograph, the structure under the designation Sh 2-305 is a zone of ionized gas.

Radiation in it occurs in the visible color range of the spectrum due to several luminaries of spectral class O. Such stars are more than ten times heavier and millions of times brighter than the Sun.

Together with five more neighboring nebulae, Sh 2-305 belongs to the giant complex of dense gas-dust clouds, and on an even larger scale – to the colossal ring-shaped star-forming region, the GS234-02 super-shell.
