Just about 30 years ago, we didn’t have any scientific proof of a planet outside our solar system. Today, thanks to advances in technology and scientific research, we've discovered over 5,300 exoplanets - alien worlds that are out there waiting to be explored. At first, these discoveries mostly involved large gas giants, but as our capabilities have expanded, we've started to uncover smaller, Earth-like exoplanets. Scientists have already found more than 50 exoplanets with masses similar to Eart

Are We Alone in the Universe? The Surprising Probability of Alien Life In this short video, we learn about the mind-blowing number of potential Earth-sized planets that may exist in the universe. According to recent studies, on average, every star has at least one planet, and one-fifth of those have Earth-sized planets. With approximately 100 billion stars in our Milky Way galaxy alone, this means there could be billions of Earth-like planets in our galaxy. And when you consider the 100 billion
