1. Introduction to Human Behavioral Biology. Astronomers discover planet made of diamond. New Earth-like planet discovered. Astronomers have discovered a potentially habitable planet of similar size to Earth in orbit around a nearby star.
A team of planet hunters spotted the alien world circling a red dwarf star called Gliese 581, 20 light years away. The planet is in the "Goldilocks zone" of space around a star where surface temperatures are neither too hot nor too cold for liquid water to form. "Our findings offer a very compelling case for a potentially habitable planet," said Steven Vogt, an astronomer at the University of California, Santa Cruz. "The fact that we were able to detect this planet so quickly and so nearby tells us that planets like this must be really common. " If confirmed, the planet would be the most Earth-like that has ever been discovered in another solar system and the first strong contender for a habitable one. Brian Greene on string theory.
