Scientists estimate that there are vastly more planets in the universe than grains of sand on Earth. This is because our universe contains billions of galaxies, and each galaxy can contain billions of stars, many of which have planets orbiting them. When these numbers are added together across the observable universe, the estimated number of planets becomes incredibly huge—far greater than the number of individual grains of sand found on all of Earth’s beaches and deserts. #scary #viral #physics

Watch Kepler-62f .. A Frozen World That Might Not Be Frozen Take a closer look at Kepler-62f, discovered in 2013 and located around 1,200 light-years away in the constellation Lyra. Kepler-62f orbits at the outer edge of its star's habitable zone, completing a year every 267 days. At that distance it should be locked in ice, but climate models show that a thick carbon dioxide atmosphere could trap enough heat to keep liquid water on its surface. Without knowing its atmosphere, scientists cannot
