Default nighttime earth
Beautiful, thank you. Also didn't realize how fast the space station actually moves over us. Love all the pictures. So far our Earth is the only one that is quite this beautiful. Makes me appreciate it even more. ginnie

Hi, Steve,

Here is the link:

http://apod.nasa.gov/apod/ap130409.html

Explanation: It's the dim star, not the bright one, near the center of NGC 3132 that created this odd but beautiful planetary nebula. Nicknamed the Eight-Burst Nebula and the Southern Ring Nebula, the glowing gas originated in the outer layers of a star like our Sun.
In this reprocessed color picture, the hot purplish pool of light seen surrounding this binary system is energized by the hot surface of the faint star.
Although photographed to explore unusual symmetries, it's the asymmetries that help make this planetary nebula so intriguing.
Neither the unusual shape of the surrounding cooler shell nor the structure and placements of the cool filamentary dust lanes running across NGC 3132 are well understood.

Explanation: As far as the eye could see, it was a dark night at Las Campanas Observatory in the southern Atacama desert of Chile. But near local midnight on April 11, this mosaic of 3 minute long exposures revealed a green, unusually intense, atmospheric airglow stretching over thin clouds. Unlike aurorae powered by collisions with energetic charged particles and seen at high latitudes, the airglow is due to chemiluminescence, the production of light in a chemical reaction, and found around the globe.

The chemical energy is provided by the Sun's extreme ultraviolet radiation. Like aurorae, the greenish hue of this airglow does originate at altitudes of 100 kilometers or so dominated by emission from excited oxygen atoms. The gegenschein, sunlight reflected by dust along the solar system's ecliptic plane was still visible on that night, a faint bluish cloud just right of picture center.

At the far right, the Milky Way seems to rise from the mountain top perch of the Magellan telescopes. Left are the OGLE project and du Pont telescope domes.

Click on this picture two times.

2013 May 03:Horsehead:A Wider view.

Click one time. Then click another time on the picture.
It's a interesting picture,and I've seen this Horsehead Nebula many times.
You can scroll around and see super bright stars.
At the bottom of this picture away from the Horsehead Nebula,you can see what looks like a super nova that has spread out.
