We chose these images because they inspire. They tell a story of a 4.5-billion-year-old planet where there is always something new to see. They tell a story of land, wind, water, ice, and air as they can only be viewed from above. They show us that no matter what the human mind can imagine, no matter what the artist can conceive, there are few things more fantastic and inspiring than the world as it already is. The truth of our planet is just as compelling as any fiction.
Earth, a free photo book from NASA features stunning imagery captured over the years by various NASA satellites. There is a hardcover version for sale, but you can also download a free pdf, or e-version
But, better than the free book is the online version that also offers interactive elements and image of the day for the four categories: atmosphere, water, land, and ice and snow.
Sixty years ago, with the launch of Explorer 1, NASA made its first observations of Earth from space. Fifty years ago, astronauts left Earth orbit for the first time and looked back at our “blue marble.” All of these years later, as we send spacecraft and point our telescopes past the outer edges of the solar system, as we study our planetary neighbors and our Sun in exquisite detail, there remains much to see and explore at home.
Every one of the images in this book is publicly available through the Internet, truly making science accessible to every citizen
