In 2019, NASA announced that an international team had found sugars essential to life in meteorites. The discovery added to the growing list of biologically important compounds that have been found in meteorites, supporting the hypothesis that chemical reactions in asteroids – the parent bodies of many meteorites – can make some of life’s ingredients.

Daniel Barth focuses on how asteroids may have delivered nucleotides that assisted in the rise of life here on Earth.

The activities and materials provided free for the How Do You Know? program are based upon Dr. Barth’s award-winning book: Astronomy For Educators. This book is used as a resource in more than 5,700 schools across the United States and in more than 50 countries world-wide. Published as an Open Educational Resource Text, it is made available from the University of Arkansas Library Press.
