How Many Earth-Like Planets Will There Be? |Space Science Documentary
Throughout the universe, trapped in the halos of dark matter, there is enough planet-making material to create at least 1,000,000,000,000,000,000,000 more Earth-like planets. A billion trillion of them. In the Milky Way alone, that would mean another 5 billion Earth-like planets over time. That’s according to new research by astronomers at the Space Telescope Science Institute in Baltimore, whose findings suggest that Earth, and the life it supports, is only among the first in a massive sprawl of potentially habitable planets that will eventually form in the universe.
