I was outside walking my cat when all the sudden I see a bright light that filled my vision. I look up from the ground to see, about a mile or two from my house, a tear shaped ball of light, going below the tree line. The center was white just outside the white was blue and then it had a tail of white and orange. It was low in the sky and didn't make a sound. I live in a town in the country and it was extremely silent outside, no talking, cars, bangs. I can't imagine what it could be. Any ideas?
