This book is titled Sidereal Heart, after Galileo's famous treatise Sidereus Nuncius (1610), the first book to be written regarding observations made through a telescope. Where Galileo presented observations of the moon, Jupiter and the stars, Sidereal Heart is made of the very material Galileo was observing. In this case, it presents a magnificent octahedrite, cut into four pieces to reveal the internal metallurgic structures including a large triolite nodule.
Many years ago, I encountered a slice of a nickel-iron meteorite—an object formed at the beginning of our solar system roughly 4.56 billion years ago. It was cool to the touch, surprisingly heavy, and had been polished and etched to reveal metallurgical structures called Widmanstätten patterns. These are patterns that are only found in meteorites, and only occur when nickel-iron cools at a phenomenally slow rate of 2 or so degrees every million years. Peering closely at these structures, I had the peculiar feeling that I was looking at something that was meant to be read. This object was like a Rosetta stone from the very birth of our solar system. It occurred to me to make a book out of a meteorite and present it as an object to be read.
