Here is a website devoted to astrobiology where you can learn about this exciting, relatively new field, and the many scientific discoveries that astrobiologists have made in the quest to better understand the world we live in and its history, as well as that of other planets within and outside of our solar system. Understanding how life got started on our planet will help us better understand how life could emerge and evolve on other worlds.
Perplexed with the idea of extrasolar planets? This link will help provide some more information! Exoplanets 101.
Astronomers have discovered planets that are similar in size to the Earth, and some that are MUCH bigger. Some planets are blazingly hot, while others are frigid, orbiting far away from their stars. One thing we’ve learned is that our own solar system is not a typical system. In fact, there might not be a typical system out there. Every system, every planet—just like every person on the Earth—is unique. And that’s pretty special.
The universe is literally teeming with planets. Do you think it’s just us?
