Framing a bright emission region
looks out along the plane of our Milky Way Galaxy toward the
nebula rich constellation
Popularly called the Tulip Nebula the glowing cloud of
interstellar gas and dust is also found in the
by astronomer Stewart Sharpless
About 8,000 light-years distant the nebula is
understandably not the only
cosmic cloud to evoke the imagery
The complex and beautiful nebula is shown here in a composite image that
from ionized sulfur, hydrogen, and oxygen atoms
into red, green, and blue colors.
Ultraviolet radiation from young, energetic
O star HDE 227018
ionizes the atoms
and powers the emission from the Tulip Nebula.
HDE 227018, is the bright star very near the blue
arc at image center.
