1 object with green and red lights

I lived out in the country at the time, and was outside on my front porch. I seen this, it was like a clear glass ball and in the middle of the ball all the way around the ship was this silver piece that had red and green blinking lights,and it like had this beam of light that came out of the bottom. I was so scared and shocked that I couldnt speak to ge tthe person with me to turn around. It was just hovering over the trees. Then all of the sudden it vanished.
