Explanation:
Sprawling across almost 200 light-years, emission nebula IC 1805 is a mix of
glowing interstellar gas and dark dust clouds about 7,500 light-years away in
the Perseus spiral arm of our galaxy. Stars were born in this region whose
nickname, the Heart Nebula, derives from its Valentine's-Day-appropriate shape.
The clouds themselves are shaped by stellar winds and radiation from massive
hot stars in the nebula's newborn star cluster Melotte 15 about 1.5 million
years young. This deep telescopic image maps the pervasive light of narrow
emission lines from atoms in the nebula to a color palette made popular in
Hubble images of star forming regions. The field of view spans about two
degrees on the sky or four times the diameter of a full moon. The cosmic heart
is found in the constellation of Cassiopeia, the boastful mythical Queen of
Aethiopia .
