Why total solar eclipses are so special
Quick Summary
More than 2500 years ago, a total solar eclipse is said to have ended a war between the Lydians and the Medes. Today, we understand the science behind eclipses, but witnessing one is still one of the most awe-inspiring experiences on Earth.
Space Explainer: Mapping Our Solar System
Our solar system contains eight planets, five recognized dwarf planets including Pluto, and well over 200 moons, along with countless asteroids and comets left over from its formation roughly 4.6 billion years ago. Every world in it formed from the same swirling disk of gas and dust around the young Sun, which is why terrestrial planets cluster near the Sun and gas giants dominate the outer solar system.
Spacecraft have now visited every planet at least once, but exploration remains wildly uneven — Mars and the Moon have been mapped in exhaustive detail, while Uranus and Neptune have each been seen up close for only a few days total, during single flybys decades ago.
