This is a close up of the Northern part of the Heart Nebula.
There is a lot that is missing in this image due to field of
view constraints, etc.
1. Sprawling across hundreds of light-years, emission
nebula IC 1805 is a mix of glowing interstellar gas and dark
dust clouds. Only about 7,500 light-years away, stars were
born in this region whose nickname - the Heart Nebula -
derives from its suggestive shape (seen here sideways).
This gorgeous, deep telescopic image of the nebula is very
colorful, but if you could travel there and gaze across these
cosmic clouds with your own eyes, are those the colors
you would really see? The short answer is no, even though
the image was made with light visible to the human eye.
Light from this and other glowing gas clouds surrounding
hot, young stars comes in very narrow bands of emission
characteristic of energized atoms within the clouds. In fact,
the nebular glow is often dominated by hydrogen atoms
emitting light in only a small fraction of that broad region of
the spectrum that we see as the color red. Adopting an
artificial color scheme commonly used for narrow band
images of emission nebulae, this beautifully detailed view
shows the light from sulfur atoms in red hues, with
hydrogen in green, and oxygen atoms in blue.
