Cosmic Traveler: Comet Izumi's Billion-Year View of Solar System
Imagine a comet, named Izumi, traveling through space for billions of years.
It comes from a very cold place far from the sun.
Izumi has seen many things!
It zipped past Mars when it was full of water and living things.
It also watched Earth change dramatically over time, starting with simple life and becoming a planet covered in oceans and colorful life.
We also learn about a special jewel found in an ancient tomb and a woman named Hypatia who studied the stars.
Comet Izumi, from the Oort Cloud, observes changes on Earth and Mars over billions of years.
The comet's journey includes a close flyby of Mars when it was teeming with water and life.
Izumi witnesses Earth's transformation, from early life to a planet covered in oceans and vibrant life.
A silica glass stone, formed by a comet impact, was found in Tutankhamen's tomb.
The story also touches on the life of Hypatia of Alexandria, a mathematician and philosopher.
