Eos is a valued source for accurate, reliable, and timely news and perspectives about the Earth and space sciences—from the Earth’s core to the far reaches of the solar system and beyond.

Eos addresses all geoscience disciplines and covers a broad range of topics, including Earth’s deep interior, tectonics, oceans, atmosphere, hydrology, solar physics, planetary bodies, geoscience history, and education, among others. It also examines the intersection of science and policy as it relates to climate change, hazards and disasters, resource development, and other societal concerns.

Eos seeks to forge strong interdisciplinary ties among Earth scientists and to place the important contributions of the Earth and space sciences in the context of social and policy-making arenas. The worldwide community of Earth and space scientists relies on Eos for timely news, overviews of topics central to broad research questions, updates on major projects and programs, opinion pieces, meeting summaries, and more.

Why Eos? The publication is named for the Greek goddess of the dawn. She represents the new light continually being shed by the Earth and space sciences on the understanding of our planet and its environment in space for the benefit of humanity.

The publication that evolved into Eos, called Transactions, American Geophysical Union, began as a way to distribute information about AGU’s annual meetings and discipline-specific sections to AGU members. Launched in 1920, it was published sporadically until 1959, when it became a quarterly. In 1969, it became monthly and added Eos to its name. In 1979, the publication became a weekly newspaper. Now, with its Web presence, Eos is freely available to all who are interested in the Earth and space sciences.
