Flashing lights in sky?

Question

Sometimes I see strange flashing lights up in the sky, they tend to be red, blue, yellow, white and green.. the thing is they don't resemble helicopters or planes because they remain perfectly motionless in the sky, I'm not saying "OMG UFO" because they very well might not be.. but what could these things be?

Answer 5

Regular stars can flash different colors as they twinkle. Twinkling is caused by atmospheric turbulence. The same thing that shakes airplanes in flight. It causes different sections of the air to have slightly different density which acts as both a natural lens and prism. The effect can be both changes in brightness and changes in color.

Answer 6

Well, I think you'd know a star if you saw it, satellites will be moving....might be a weather balloon or a string of them. The UFO phenomenon you question tends to be lights that blink off then blink on in another location and make quick impossible turns. Moving in ways that defy known aeronautics.

Answer 7

Could be a couple of different things.

An airplane that is approaching your location wouldn't appear to move.

Stars, especially bright ones low in the sky, will twinkle all different colours (red, yellow, white, blue, purple, green, etc.) as the starlight passes through the atmosphere, especially on hot nights or when the upper atmosphere is turbulent, or if there is a lot of dust or moisture in the upper air.
