The discovery of exoplanets has opened up new possibilities for life beyond Earth from "summary" of Astrophysics for People in a Hurry by Neil deGrasse Tyson
The discovery of exoplanets, or planets beyond our solar system, has revolutionized our understanding of the universe. These worlds, some similar in size to Earth, orbit stars in the vastness of space, raising the tantalizing possibility of life beyond our own planet. With the advancement of technology, astronomers have been able to detect these distant worlds through various methods, such as measuring the dimming of a star as a planet passes in front of it or observing the wobble of a star caused by the gravitational pull of an orbiting planet. The sheer number of exoplanets that have been discovered is staggering, with thousands confirmed and many more awaiting further study. Some of these planets are located in the "habitable zone" of their parent stars, where conditions may be right for liquid water to exist on their surfaces - a key ingredient for life as we know it. This has given rise to the possibility that there may be other planets out there that could potentially harbor life forms beyo...
