Ripples on the Cosmic Ocean

A cosmic panorama of how the solar system has molded our past and may spell our end. From comets hitting Jupiter to vast explosions on the Sun, Dagomar Degroot masterfully shows that our understanding of some of the world's greatest threats has come from watching the stars

Luke Kemp, author of Goliath's Curse

This dazzling book is an enormous contribution, challenging us to re-envision the universe and our place in it. With exquisite insight, Dagomar Degroot reveals how our environment is much more expansive than our own planet, and indeed ripples out into the cosmos

Sarah Stewart Johnson, author of The Sirens of Mars

Dagomar Degroot has boldly taken environmental history where no historian has gone before. In this beautifully written and handsomely illustrated book, Degroot shows how dynamic components of the solar system have affected both earthly environments and human ideas over the last five centuries. Part history of astronomy and astronomers, part super-macro environmental history, the book brims over with both interesting anecdotes and arresting perspectives on our place within the cosmos

Ripples on the Cosmic Ocean brings us a new arena of history, the history of our collective engagement with our planetary neighbors in the inner solar system. Dagomar Degroot has constructed an amazing synthesis of how cultural projections, and gradually the observational sciences, have brought the environmental histories of the Sun, the Moon, Venus, Mars, and the asteroids into sharper and sharper focus. Simultaneously, Degroot shows how our explorations of environments in the inner solar system have illuminated the critical features of our home planet Earth. This is a book that will be widely read as we grapple both with our emerging efforts to inhabit near-earth environments and with the pressing problem of planetary sustainability here on Earth.

John L. Brooke, author of Climate Change and the Course of Global History

A beautifully illustrated and flowing account of the place of our world in the vastness of the cosmos. Ripples on the Cosmic Ocean offers a stark warning about the interplanetary hazards our world faces, but it also offers hope: about our potential to explore the cosmic high seas and our potential to save our own little island. Degroot sets some awesome challenges, but he opens up some liberating possibilities
