Logarithmic Scale of the Observable Universe by Pablo Carlos Budassi: How to See the Universe in a Single Image

In 2012, an Argentinian man named Pablo Carlos Budassi created an infographic and artistic representation of the Observable Universe. Since then, the image has captured the imagination of astronomy enthusiasts around the world. This artwork is known as the “Radial Logarithmic Illustration of the Observable Universe” or the “Logarithmic Scale of the Observable Universe.”

To achieve this project, Budassi used a logarithmic scale to detail astronomical objects at varying distances and sizes. Here’s a closer look at how this image works and how it manages to show the universe in a single frame.

What Do We Mean by the “Observable Universe”?

When we refer to the “Observable Universe,” we’re talking about the portion of space that can currently be detected and studied using existing technology. While the full universe is likely far more vast and beyond full human comprehension, this image allows us to visualize a significant portion of it.

What Is a Logarithmic Map? The Logarithmic Scale of the Observable Universe

A logarithmic map is a graphical representation where distances are scaled in such a way that they fit along a single plane or line. With the logarithmic scale Budassi used, we can perceive a vast range of sizes—from nearby objects in our solar system to the largest and farthest structures in the entire universe.

What Does “Order of Magnitude” Mean in the Observable Universe?

Logarithmic scales help us understand the vast differences in size and distance between celestial objects. Every “step” on this scale represents an increase or decrease by an order of magnitude. Generally, this means something is either ten times larger or ten times smaller.

Using this method, we can explore everything from nearby planets and stars to distant galaxies and the lingering radiation from the Big Bang.

Where Is the Center of the Universe According to NASA?

This is a difficult question to answer. In Budassi’s logarithmic map, the solar system is placed at the center. As we move outward along the radial scale, distances become compressed to allow room for distant cosmic structures.

That’s why we must understand that there is no absolute center of the universe. The positioning of the solar system at the center is simply a conceptual or artistic choice made for the sake of representation.

Is There a Country on Earth That’s the Center of the Universe?

While the illustration puts the solar system at its center, it would be incorrect to interpret this literally—as though Earth were the cosmic epicenter. Instead, the image is a tool to help us appreciate the incredible diversity and beauty of the universe in one artistic visualization.

Budassi’s Logarithmic Scale of the Observable Universe invites us to reflect on the vastness of the cosmos and to marvel at its complexity. Isn’t it awe-inspiring to realize we are part of such an immense cosmic tapestry?
