A Logarithmic Map of the Entire Observable Universe

Among the scientific community, it’s widely believed that so far humans have only discovered about 5% of the universe.

Yet, despite knowing about just a fraction of what’s out there, we’ve still managed to discover galaxies billions of light-years away from Earth.

This graphic by Pablo Carlos Budassi provides a logarithmic map of the entire known universe, using data by researchers at Princeton University and updated as of May 2022.

How Does the Map Work?

Before diving in, it’s worth touching on a few key details about the map.

First off, it’s important to note that the celestial objects shown on this map are not shown to scale. If it was made to scale with sizes relative to how we see them from Earth, nearly all of the objects would be miniscule dots (except the Moon, the Sun, and some nebulae and galaxies).

Secondly, each object’s distance from the Earth is measured on a logarithmic scale, which increases exponentially, in order to fit in all the data.

Within our Solar System, the map’s scale spans astronomical units (AU), roughly the distance from the Earth to the Sun. Beyond, it grows to measure millions of parsecs, with each one of those equal to 3.26 light-years, or 206,000 AU.

Exploring the Map

The map highlights a number of different celestial objects, including:

Nature Timespiral: The Evolution of Earth from the Big Bang

Since the dawn of humanity, we have looked questioningly to the heavens with great interest and awe. We’ve called on the stars to guide us, and have made some of humanity’s most interesting discoveries based on those observations. This also led us to question our existence and how we came to be in this moment in time.

That journey began some 14 billion years ago, when the Big Bang led to the universe emerging from a hot, dense sea of matter and energy. As the cosmos expanded and cooled, they spawned galaxies, stars, planets, and eventually, life.

In the above visualization, Pablo Carlos Buddassi illustrates this journey of epic proportions in the intricately designed Nature Timespiral, depicting the various eras that the Earth has gone through since the inception of the universe itself.

Evolutionary Timeline of the World

Not much is known about what came before the Big Bang, but we do know that it launched a sequence of events that gave rise to the universal laws of physics and the chemical elements that make up matter. How the Earth came about, and life subsequently followed, is a wondrous story of time and change.

Let’s look at what transpired after the Big Bang to trace our journey through the cosmos.
