Wonder and Mystery above Chili

This beautiful image shows a wide stretch on the horizon. Included in this horizon are 5 extremely large telescopes canopied by a myriad of stars and astronomical objects. To the far left, one might notice that the bottom of the picture is glowing a rather orange color, although the rest f the sky indicates that it is past sunset. This light is not a sunset but is rather referred to as zodiacal light. This is formed when light reflects off of dust particles in the milky way. Above this zodaical light, Venus can be observed, shining brightly. The reason Venus shines is also a result of the reflection of sunlight. In the middle of the picture, a large arc of our milky way can be seen, and it consumes most of this image. However, this is just one of manyy branches in the enormous galaxy that we live in. Two other galaxies besides our own can also be viewed in this picture, located just under the wide arch of our milky way galaxy. These galaxies are named the small magellanic and the large magellanic galaxies. Many constellations can be seen in this picture including Orion, Gemini, and Centaurus. The orange dot above one of the telescopes is actually the moon, as this picture was taken during a total lunar eclipse.
