Any model of the origin of the solar system must explain why all the planets orbit the Sun in the same direction and in nearly the same plane. One model that wasdevisedexplicitly to address this issue was the tidal hypothesis, proposed in the early 1900s.Two nearby planets, stars,...

But was lightning the main energy source? Maybe not. For the 2023 study, lead author Vladimir Airapetian used data from NASA's Kepler mission to suggest that powerful solar eruptions called superflares from the young sun could have triggered chemical reactions when colliding with Earth's atmosphe...

Hence, the solar system is somewhat special, but the degree of fine-tuning that may be necessary for the emergence of life is not excessive. Finally, with n -body simulations, we show that when the two giant planets are close to the 2:1 mean motion resonance, the asteroid belt is ...
