This is an image of the M106 galaxy. The image itself is made of pictures taken from Earth and space of the galaxy. M106 is 23.5 million light-years from Earth. That makes the length of this image close to 80,000 light-years across.
This is an image of the Trifid Nebula. It is near the center of Sagittarius, the archer. Trifid gets its name from the three prominent dust lanes in its center. Most of this nebula's glow comes from the single massive star at its center.
This is the Great Nebula inside Orion. It is visible to the naked eye as a small fuzzy patch. This image is an illusory-color composite of four different colors of infrared light. The green glow in the image is caused by the reflection of the light of the stars off of dust filaments that are scattered throughout the region.
