Astronomers probably saw an exoplanet collision for the first time.

Astronomers have observed the Kepler-107 star and the neighboring planets Kepler-107b and Kepler-107c. The latter scientists

discovered a strange feature - it was almost twice as heavy as its neighbor, Kepler-107b, and much denser than him. Its density was 12.6 g / cm ³, and weight - 9.3 times the Earth.

According to the hypothesis of scientists, Kepler-107crelatively recently experienced a cosmic catastrophe - it is very likely that it collided with a neighboring planet. As a result, now Kepler-107c is a bare core - this explains the extremely high density of the cosmic body.

Scientists suggest that the core is 70% composed of iron and its various compounds. Now researchers are trying to mathematically confirm their hypothesis.

Formerly astronomers from harvard universityfound that almost all exoplanets found by mankind have no life due to the weak emission of the stars around which they rotate. The fact is that the red dwarfs, around which practically all existing exoplanets rotate, simply cannot give the planet the necessary amount of radiation to start the process of photosynthesis.
