The brightest heavenly bodies in the sky are Venus, Jupiter, and sometimes Mars and, of course, the Moon.

Venus is the bright yellow of the evening or morning star, shining in the sky on the background of evening or dawn. Maximum brightness of Venus can reach up to 4.3 m, and she is the third brightness of the sun in earth's sky after the sun and the moon. It so well reflects the light of the Sun that it is relatively easy to see and day, especially if you know the location. It manifests itself in the form of tiny blinking white dots.

For UFOs often take stages of rockets, parts of space ships burning in the atmosphere, the launches of various missile technology for military purposes, etc., and traces from them. They attract attention mostly in the dark, but in the day time have a greater aura of mystery.

Formation of the track of the launch vehicle occurs in the tropopause (the layer between the troposphere and stratosphere), which sharply reduced the vertical temperature gradient. The emergence of the so-called "jellyfish" influenced by water vapor, which are subject to enhanced condensation.
