Ice crystals like those that create cirrus clouds high in the atmosphere, created this wonderful vision above the Caribbean coastal metropolis of Cartagena, Colombia on April 10, 2010. Such a phenomenon is known as a solar halo. The lunar versions are more common in my experience. The citizens of Cartagena were treated to the awesome sight (and probably a few sore necks) for several hours. I used my Sony Cyber-shot.
An asteroid or comet headed for Earth is the only large-scale natural disaster we can prevent. Working together to fund our Shoemaker NEO Grants for astronomers, we can help save the world.
