Astrobiology (general): September 2015

Today the House Science, Space, and Technology Committee helad a hearing that reviewed the scientific methods employed to search for life, examine recent scientific discoveries in the field of astrobiology (the study of the origin, evolution, distribution, and future of life in the universe), and assess the prospects of finding life beyond Earth over the next decade.

A first draft of the "tree of life" for the roughly 2.3 million named species of animals, plants, fungi and microbes -- from platypuses to puffballs -- has been released.
