Mysterious Dancing Lights In Afghanistan

This isn't a painting. It's not from a movie. It's not a strange astronomical event. This is real — what you can see when certain helicopters in Afghanistan touch down on sandy ground, raising dust, causing mysterious arcs of light to loop and dance through the air.<p>This doesn't always happen.

APOD: The Eskimo Nebula from Hubble and Chandra (2013 Jul 30) Image Credit: X-ray: NASA/CXC/IAA-CSIC/N. Ruiz et al.; Optical: NASA/STScI http://apod.nasa.gov/apod/ap130730.html Explanation: In 1787, astronomer William Herschel discovered the Eskimo Nebula. From the ground, NGC 2392 resembles a person's head surrounded by a parka hood. In 2000, the Hubble Space Telescope imaged the Eskimo Nebula in visible light, while the nebula was imaged in X-rays by the Chandra X-ray Observatory in 2007. The above combined visible-X ray image, with X-rays emitted by central hot gas and shown in pink, was released last week. From space, the nebula displays gas clouds so complex they are not fully understood. The Eskimo Nebula is clearly a planetary nebula, and the gas seen above composed the outer layers of a Sun-like star only 10,000 years ago. The inner filaments visible above are being ejected by strong wind of particles from the central star. The outer disk contains unusual light-year long orange filaments. The Eskimo Nebula spans about 1/3 of a light year and lies in our Milky Way Galaxy, about 3,000 light years distant, toward the constellation of the Twins (Gemini). http://chandra.harvard.edu/photo/2013/ngc2392/ Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130730 #APOD
