Earth & Sky

Earth & Sky

Earth & Sky is a daily radio series presenting information about science and nature. It began broadcasting in 1991. Earth & Sky is the creation of producers Deborah Byrd and Joel Bloch, also the hosts, whose program "Star Date" began broadcasting in the U.S. in the late 1970s.

Earth & Sky currently presents 90-second and 60-second radio spots (called "modules") on a wide variety of scientific topics, communicating through terrestrial radio as well as satellite radio and internet radio. Earth & Sky is aired one or more times daily on more than 1,000 commercial, NPR, and other public radio stations, 80 affiliates stations for the sight-impaired, and across 35 channels on both XM and Sirius satellite radio in the United States. Abroad, the programming is heard on American Forces Radio, Voice of America Radio, World Radio Network, and others.

The information on Earth & Sky comes directly from scientists. The journalists who produce the Earth & Sky radio program and web site speak to several scientists each day, dozens each week and hundreds each year. More than 500 scientists have joined Earth & Sky as volunteer advisers. Earth & Sky science advisers suggest content, give feedback, recommend other experts, and review scripts for accuracy before they are recorded for broadcast.

Earth & Sky features many different fields of science. In 2006, its focus was on nanotechnology, women in science, observing the Earth, astrophysics and space, and the human world.
