Explanation:
What's happening at the center of the Trifid Nebula?
Three prominent
dust lanes that give the
Trifid its name all come together.
Mountains of opaque dust
appear near the bottom, while other dark filaments of
dust are visible threaded throughout the nebula.
A single massive star
visible near the center causes much of the
Trifid's glow.
The Trifid, cataloged as
M20,
is only about 300,000 years old, making it among the youngest
emission nebulas known.
The star
forming nebula lies about 9,000
light years away toward the
constellation of the Archer (Sagittarius).
The region pictured here
spans about 20 light years.
