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 .
