  1. Introduction

    Have a question about life in the universe? You’ve come to the right place.

    Ask an Astrobiologist is a service to answer astrobiology questions from the public, both about the origin and evolution of life on Earth and looking forward to the search for life on other worlds. If you have a question, begin by searching our database of more than 1,000 previous questions and answers. If you can’t find the information there, click Submit a Question and have your question personally answered by NAI’s Senior Scientist.

    Note that because of the backlog, it typically takes 2-3 weeks before your answer is posted. Also note that we don’t do school homework, and we try to select questions for reply that are focused on the science of astrobiology.
