“Here is Willis’s fundamental argument: The more we learn about Earth—our one ‘pale blue data point’ for a planet on which life has definitively arisen—the more qualified we will be to recognize signs of life elsewhere. . . . [A] joyful account.”—Steven Poole, The Wall Street Journal
 
A thrilling tour of Earth that shows the search for extraterrestrial life starts in our own backyard.
 
Is there life off Earth? Bound by the limitations of spaceflight, a growing number of astrobiologists investigate the question by studying life on our planet. Astronomer and author Jon Willis shows us how it’s done, allowing readers to envision extraterrestrial landscapes by exploring their closest Earth analogs. With Willis, we dive into the Pacific Ocean from the submersible-equipped E/V Nautilus to ponder the uncharted seas of Saturn’s and Jupiter’s moons; search the Australian desert for some of Earth’s oldest fossils and consider the prospects for a Martian fossil hunt; visit mountaintop observatories in Chile to search for the telltale twinkle of extrasolar planets; and eavesdrop on dolphins in the Bahamas to imagine alien minds.
 
With investigations ranging from meteorite hunting to exoplanet detection, Willis conjures up alien worlds and unthought-of biological possibilities, speculating what life might look like on other planets by extrapolating from what we can see on Earth, our single “pale blue dot”—as Carl Sagan famously called it—or, in Willis’s reframing, scientists’ “pale blue data point.”

The first detailed history of the Royal Observatory at Greenwich covering the period after the retirement of George Airy, seventh Astronomer Royal, in 1881.

This book charts an under-researched period in the long history of the Royal Observatory at Greenwich. It covers both the scientific and social-political history of the Royal Observatory, focusing on its significance within the history of astronomy and UK history more generally. Using a wealth of archival material—much of which was previously unpublished—Lee T. Macdonald's narrative brings the day-to-day operations of the Observatory to life and reveals how its mission in positional astronomy, combined with its cutting-edge research in photographic mapping and the study of solar eclipses, continues to expand the frontiers of astronomical research. 

The inside account of how astronomers were able to build the world’s largest observatories on Hawai‘i’s most revered mountain.

In July 2019, a demonstration erupted on Hawai‘i Island to prevent the construction of the Thirty Meter Telescope, which, if built, would be one of the largest and most advanced ground-based telescopes in the world. For months, thousands of people camped on the access road leading to the proposed location: Mauna Kea, a dormant volcano, the highest point in Hawai‘i, and a sacred site for Native Hawaiians. The standoff in 2019 was not the first. For decades, activists had resisted attempts to build the TMT and its predecessors. Even so, many astronomers were startled by opposition to the TMT and the discoveries it promised. Astronomers were focused on the stars; Native Hawaiians and environmentalists were concerned about not only the sky, but also the land.

The Stars of Mauna Kea traces the history of astronomy on Hawai‘i Island, shedding new light on why scientists were granted access to the volcano in the first place. Beginning in 1959, when Hawai‘i became the fiftieth US state, it chronicles the ways astronomers benefited from Hawai‘i’s colonial past to gain free and exclusive land use rights on what had long been the archipelago’s most revered mountain. Drawing on unprecedented archival research and extensive interviews, Pascal Marichalar carefully charts the course of astronomical development on Mauna Kea. He describes the devastating tsunami that led a local businessman to contact scientists just as a renowned astronomer was scouting for places to observe the stars; the controversial authority the University of Hawai‘i assumed over the volcano after 1964; the environmental opposition to the first large international project, the Canada-France-Hawai‘i Telescope; and the resistance to telescope development that became a major focus of the Hawaiian sovereignty movement. Marichalar introduces readers to scientists working on Mauna Kea, as well as the people living in the mountain’s shadow, including key opposition figures involved in recent events.

Like the dark matter that holds together rotating galaxies, the colonial forces that have shaped Hawai‘i exert a gravitational pull on the science undertaken on the volcano’s summit. The Stars of Mauna Kea brings readers inside an ongoing debate over the morality of scientific research conducted on contested ground. 

See the Universe as astronomers do: These thirteen graphs distill the cutting-edge discoveries of the cosmos—from planets and stars to galaxies, to ripples in spacetime itself.

From the front page of newspapers to your favorite t-shirt, the visual language of the cosmos is pervasive. Yet while you may have seen stunning images of planets, nebulae, and even the shadow of a black hole, pretty pictures alone cannot reveal the universe. Whether you’re looking for planets outside our solar system, searching for dark matter, listening for ripples in spacetime, or looking back to very early times, to truly understand the cosmos you need graphs.

In this fully illustrated and engaging book, astronomers Chris Lintott and Jeffrey Grube and data scientist Daina Bouquin focus on thirteen graphs to offer a tour of the major astronomical discoveries of the last century. Meet the HR diagram, which tells us about stellar lives; marvel at the Hubble diagram’s evidence for the expansion of the Universe; understand special relativity through Minkowski spacetime; and turn back time to the earliest visible light of the cosmic microwave background. With fascinating stories of discovery and accessible science for understanding ongoing debates, this book proves that while a picture may be worth a thousand words, a graph can show you the universe.
