What Could We See?

An interactive visualization of the observable universe

What Could We See? (1600-1900)

What is this?

This visualization provides us with a general idea of how much of the universe is visible at different times. It shows the increase in number and variety of celestial bodies that we could observe as telescopic technology evolved.

How Accurate Is It?

The chart presents a conceptual understanding of advances in astronomical observation. The total number of observable stars, variable stars, and similar data are interpolated based on records that were only avaialbe at certain years.

Does Position Matter?

The simple answer: no. The position of representations of stars, planets, comets, and galaxies are randomly determined. However, for planets in the solar system, they are positioned in the order of increasing distance to the sun.
