Looking for life


  • Randy Showstack


With meteorites and extreme environments on Earth providing tantalizing evidence about the possibility of life on other planets, NASA this month issued a draft notice to form an astrobiology institute.

The institute, which would include an interdisciplinary team of researchers from the United States and possibly other countries, will try to coordinate and encourage research in exobiology and evolutionary biology, according to NASA. The institute will explore such questions as how habitable worlds form and evolve, how the Earth and its biosphere influence each other, and how other biospheres can be recognized.
