a flash of light going very very very fast which vanished like in invisible mode after emitting/blinking a blue light one time.

I was checking out a steel post I installed for my shade in the backyard, eyes up to the sky, when a flash of light (yellowish/white) surprised me in the sky. It was not far away like a star, maybe lower than a plane would be, it's hard to tell because it was night time. In a blink of an eye the thing that was moving forward (straight line movement) emitted a blue light (blinking) and totally disappeared, vanished. All of this happened very fast, like crazy fast! I didn't perceive any sound emission from that thing. I felt like that thing was defying the law of physics.
