Flying over the unlit side of Saturn's rings, the Cassini spacecraft captures Saturn's glow, represented in brilliant shades of electric blue, sapphire and mint green, while the planet's shadow casts a wide net on the rings.

NASA Cassini Views Titan's South pole: Orange and Blue Hazes
This view from NASA's Cassini spacecraft looks toward the south polar region of Saturn's largest moon, Titan, and shows a depression within the moon's orange and blue haze layers near the south pole.
The moon's high altitude haze layer appears blue here; whereas, the main atmospheric haze is orange.
The difference in colour could be due to particle size of the haze. The blue haze likely consists of smaller particles than the orange haze.
The depressed or attenuated layer appears in the transition area between the orange and blue hazes about a third of the way in from the left edge of the narrow-angle image.
The moon's south pole is in the upper right of this image. This view suggests Titan's north polar vortex, or hood, is beginning to flip from north to south.
The southern pole of Titan is going into darkness as the sun advances towards the north with each passing day. The upper layer of Titan's hazes is still illuminated by sunlight.
Images taken using red, green and blue spectral filters were combined to create this natural colour view. The images were obtained on Sept. 11, 2011 at a distance of approximately 83,000 miles (134,000 kilometers) from Titan. Image scale is 2,581 feet (787 meters) per pixel.

The bright stars of the Orion constellation
Head to Toe by Rogelio Bernal Andreo (USA)
The bright stars of the Orion constellation seen within a skyscape of fainter stars, gas and dust, which is invisible to the naked eye.
Orion is laid out from left to right in this photograph while a huge cloud of gas and dust in which new stars are forming lies below the three stars of Orion’s belt; bright red and blue supergiant stars mark his shoulder and knee.
The long exposure time and use of special filters allows us to see the hidden beauty behind this familiar constellation.
