Gas giants may face one time a year, say researchers

The researchers studied the features of the collision of giant planets with each other and found that such collisions may occur in our galaxy often.

A team of scientists from the Institute for Nuclear Research of the Russian Academy of Sciences headed by VI Dokuchaev conducted a study of indications accompanying the collision of giant planets. The researchers found that the number of collisions in our Milky Way galaxy is 0.01 to one collision per year.

In an inelastic collision with a small relative velocity and a small parameter of the collision of the planet may lose enough kinetic energy to their union was. In other cases, the planet experienced a slight tangential collision and fly, without causing significant damage to each other.

Collision of planets accompanied by heating, which leads to outbursts in the optical, near UV and radio ranges. Researchers estimate that in our galaxy there were 0.01 to 1 radio bursts a year for about 1.5 hours each, the frequency of which point to the origin of the outbreak as a result of collisions of gas giants.
