E-grāmata: Little Book of Exoplanets

"The first detection in 1995 of a planet orbiting a sun-like star outside our solar system marked the dawn of a new age of discovery-one that has rapidly transformed astronomy and our broader understanding of our place in the universe. Nearly five thousand exoplanets have been identified since then, with the pace of discovery only accelerating following the launch of missions like NASA's Transiting Exoplanet Satellite Survey and others to come. We now know that most sun-like stars host their own systems of planets analogous to our solar system, and a few of these planets may potentially be like Earth. But arguably the most remarkable discoveries so far have been of planets with unexpected, decidedly un-Earth-like properties, which have upended what we thought we knew about the origins of planets and planetary systems. The Little Book of Exoplanets provides a concise, cutting-edge introduction to this field for general readers, written by leading Princeton exoplanet scientist Josh Winn. It offers an accessible view into the sophisticated detective work astronomers perform to detect and characterize exoplanets, and describes the surprising, sometimes downright bizarre planets and systems we have found. Winn explains how these discoveries are revolutionizing astronomy, and explores the current status and future of our search for another Earth. He concludes with a reflection on how our discovery of exoplanets changes our perspective on the universe"--

A concise and accessible introduction to exoplanets that explains the cutting-edge science behind recent discoveries

For centuries, people have speculated about the possibility of planets orbiting distant stars, but only since the 1990s has technology allowed astronomers to detect them. At this point, more than five thousand such exoplanets have been identified, with the pace of discovery accelerating after the launch of NASA’s Transiting Exoplanet Survey Satellite and the Webb Space Telescope. In The Little Book of Exoplanets, Princeton astrophysicist Joshua Winn offers a brief and engaging introduction to the search for exoplanets and the cutting-edge science behind recent findings. In doing so, he chronicles the dawn of a new age of discovery—one that has rapidly transformed astronomy and our broader understanding of the universe.

Scientists now know that many Sun-like stars host their own systems of planets, some of which may resemble our solar system and include planets similar to the Earth. But, Winn tells us, the most remarkable discoveries so far have been of planets with unexpected and decidedly un-Earth-like properties, which have upended what we thought we knew about the origins of planetary systems. Winn provides an inside view of the sophisticated detective work astronomers perform as they find and study exoplanets and describes the surprising—sometimes downright bizarre—planets and systems they have found. He explains how these discoveries are revolutionizing astronomy, and he explores the current status and possible future of the search for another Earth. Finally, drawing on his own and other scientists’ work, he considers how the discovery of exoplanets and their faraway solar systems changes our perspectives on the universe and our place in it.
