Astronomers and scientists have all long been observing and studying the universe to find potential hubs of life.
New research and calculations propose that there could be more Earth-like planets in our galaxy than we previously have imagined.
Currently, Earth is the only habitable planet known to humans however, NASA is conducting missions to find life beyond Earth such as on Jupiter’s moon, Europa. According to research, there could be life under Europa’s icy crust.
Astronomers have discovered approximately 4000 exoplanets outside of our solar system that are a similar size to earth.Also Read– New data reveals fires in the Amazon could be as bad as last year
New technology is ready to be launched in 2021 like NASA’s James Webb Space Telescope. This technology will help astronomers peek into the atmosphere of Earth-like planets across our Milky Way galaxy.
In order for a planet to be considered similar to Earth, it needs to meet a number of certain criteria. The planet needs to be the size of Earth, it needs to orbit a G-star, and it needs to be at a certain distance from its star. Orbiting at a habitable zone from its star makes the planet not too cold and not too hot, perfect for liquid water and thus life on its surface.
Astronomer Jaymie Matthews from the University of British Columbia says, “Our Milky Way has as many as 400 billion stars, with seven percent of them being G-type.” “That means less than six billion stars may have Earth-like planets in our Galaxy,” he added.
