Orion Nebula in Surrounding Dust
From NASA’s Astronomy Picture
of the Day
Opaque to visible light, dust is created in the outer atmosphere of massive cool stars and expelled by a strong outer wind of particles.
The Trapezium and other forming star clusters are embedded in the nebula. The intricate filaments of dust surrounding M42 and M43 appear gray in the image below, while central glowing gas is highlighted in brown and blue.
Over the next few million years much of Orion's dust will be slowly destroyed by the very stars now being formed, or dispersed into the Galaxy.
