"In the grand tradition of Carl Sagan and Neil deGrasse Tyson, we now have a new tour guide to the cosmos."―Charles Cockell, Professor of Astrobiology, University of Edinburgh
"Absorbing, informative, and entertaining."―Kirkus (starred)
Riveting and timely, a look at the research that is transforming our understanding of the cosmos in the quest to discover whether we are alone.
For thousands of years, humans have wondered whether we're alone in the cosmos. Now, for the first time, we have the technology to investigate. But once you look for life elsewhere, you realize it is not so simple. How do you find it over cosmic distances? What actually is life?
As founding director of Cornell University's Carl Sagan Institute, astrophysicist Lisa Kaltenegger has built a team of tenacious scientists from many disciplines to create a specialized toolkit to find life on faraway worlds. In Alien Earths, she demonstrates how we can use our homeworld as a Rosetta Stone, creatively analyzing Earth's history and its astonishing biosphere to inform this search. With infectious enthusiasm, she takes us on an eye-opening journey to the most unusual exoplanets that have shaken our worldview—planets covered in oceans of lava, lonely wanderers lost in space, and others with more than one sun in their sky! And the best contenders for Alien Earths. We also see the imagined worlds of science fiction and how close they come to reality.
With the James Webb Space Telescope and Dr. Kaltenegger’s pioneering work, she shows that we live in an incredible new epoch of exploration. As our witty and knowledgeable tour guide, Dr. Kaltenegger shows how we discover not merely new continents, like the explorers of old, but whole new worlds circling other stars and how we could spot life there. Worlds from where aliens may even be gazing back at us. What if we're not alone?

Kaltenegger tells an engaging story which revolves around a basic idea. Is there any earths out there like ours? Her answer: maybe! So what do we need the book for? Well, Kaltenegger to take the next steps to explain what are the conditions needed for those earths, what would it be like on those planets, and do we even have any indication they exist. Along the way, she gets in some good jokes and her love for this subject truly shines through.
Depending on your love of science, you may find this to be a must read or it may lose some steam by the end. While I enjoyed all of it, the concluding chapters start to feel a bit repetitive. There are also some memoir type tangents that range from perfectly placed to completely misplaced. These are small issues and the good of the book well outweighs any faults.

Several other impactful observations she makes that I want to highlight are the diversity of input in the search for life. In this she means both the value people in a variety of disciplines can contribute, and the variety of different genders, cultures, religions, etc. I found it so impressive that the head of her research team (a man) turned down her offer to go make copies of their PowerPoint presentation and delayed the presentation so he could do it himself and not put her as a woman in a position to be viewed as a secretary incredibly powerful, and a thing that often gets overlooked.
The other thing is that when you think about it and view Earth from the universal perspective and not the lowly human standing on the Earth’s surface, it really is like we’re on a spaceship hurtling through the universe and we are lucky enough that our spaceship sustains us rather well. But as any astronaut could tell you, they spend a lot of time doing maintenance to avoid crucial things breaking, something we should consider on our journey on Spaceship Earth.
