Description

The best-selling book on Astrophysics returns, renewed and enriched! The new edition contains many additional chapters, impressive photographic material, and an entirely new design with improved structure. It has also been updated to include the most important developments in the fields of Astrophysics and Space Science.

New, updated, and expanded edition

  • +25% more content: with additions in all sections of the book and new chapters.
  • Improved illustration: many new images have been added and the existing ones have been enhanced.
  • Book update: updated with the latest developments in the fields of Astrophysics and Space Science.
  • New modern layout and pagination: the book is much more readable and enjoyable, with color almost everywhere.

Since ancient times, humans have turned their gaze to the stars, overwhelmed by feelings of awe and wonder. What were those tiny celestial lights that accompanied our nights? In recent centuries, humanity has made tremendous scientific progress. We have explained the nature of stars and deeply understood the processes occurring within them, while our spacecraft have traveled to the far reaches of our solar system. But we did not stop there. We now have the ability, through our observations, to travel in our minds and study objects that are billions of light-years away from us, billions of years in the past.

This book is a fascinating journey into the world of Astrophysics and its most impressive aspects. Within its pages unfold the exotic conditions of the planets in our solar system, the quest to find new "worlds," the epic story of the birth and death of stars, mysterious black holes and dazzling quasars, the past and future of the Universe, the search for extraterrestrial life, and many more exciting chapters of Astrophysics and Astronomy.

Through simple explanations of physical phenomena and rich illustrations, the reader will discover the allure of space exploration and will be able to understand better than ever the place of humans in the Universe.

Read an excerpt:

"The Sun is an unimaginably large object, 109 times greater in diameter than the Earth. Yet, along the distance from Earth to Sun, 107 objects the size of our Sun could fit, if we placed them side by side³. To see this with a simple practical example from our everyday life: if our planet were the size of a soccer ball, then the Sun would be the size of a large eight-story apartment building, located at a distance of more than 2,500 meters from the Earth! 

If the above does not seem convincing enough about how large and empty is the space between celestial bodies, we can utilize the maximum speed at which information can travel in the Universe, the speed of light."

    The excellent Mr. Kastanas, through the pages of his book To the Stars, guides us with clarity on a journey to understand the universe. With the special ability that characterizes him as a charismatic communicator of his beloved science, he conveys with simplicity and scientific accuracy concepts that for many seem inaccessible. The book is addressed to everyone—regardless of age or level of knowledge—as its structure is friendly and well-crafted, offering not only knowledge but also rich visual material with stunning images that enhance the experience.
