The universe continues to be an enigma to be deciphered by science. Despite years of studies and investigations by researchers and scientists, We still cannot completely map the borders of everything around us. However, current astronomers are already working to make this a reality.
The night sky has fascinated humanity since the most primitive times, a curiosity so intense that it gave rise to several scientific fields dedicated to the study of the cosmos. As a result, we are constantly trying to understand why reality appears the way we observe it.
To create a ‘map’ of the universe, several teams of researchers are using different methods to map all celestial objects. Just as a world map represents the Earth, the scientists’ idea is to develop a cosmic atlas that presents all the stars, moons, planets and everything present in space.
While some groups attempt to map specific regions, others seek to actually create a map of the universe. After all, how can astronomers map everything in space?
It is an extremely complex task, as estimates suggest the existence of up to 400 billion stars and 100 billion planets in the Milky Way alone, among countless other celestial structures. Furthermore, the US National Aeronautics and Space Administration (NASA) estimates that there are about 2 trillion galaxies in the observable universe.
“The universe suddenly appears much more crowded, thanks to a deep-sky census gathered from surveys by NASA’s Hubble Space Telescope and other observatories. Astronomers have come to the surprising conclusion that there are at least 10 times more galaxies in the observable universe than previously thought,” NASA explains.
‘Maps’ of the universe
One of the biggest challenges of this type of mapping is the movement of celestial bodies.. For example, the Earth continually moves in a regular, predictable orbit around the Sun. On the other hand, there are millions of asteroids, many of which have trajectories that can vary and become irregular in the long term due to gravitational interaction with other celestial bodies.
Using mathematical calculations of the distances between stars, it is possible to understand where we are in the universe. Thus, the Gaia mission, from the European Space Agency (ESA), created a map of the Milky Way with incredible precision. Data from more than a billion stars were used, as well as comets, asteroids and other objects in the Solar System.

How to map the cosmos?
It was through the study of North American astronomer Henrietta Swan Leavitt that scientists discovered that Cepheid variable stars can be used to measure intergalactic distances.
Later, American astronomer Edwin Hubble identified redshift, and it made understanding the vastness of the universe a little simpler.
Redshift is a phenomenon that changes the frequency of light from a distant celestial object. For example, the further away a star is in our expanding universe, the greater its redshift.
Euclid Space Telescope
Even with all the difficulties surrounding the objective, an ESA team is also developing a map of the observable universe. With data collected by the Euclid Space Telescope, launched in July 2023, mission researchers are compiling images to create a cosmic atlas.

The team has already released the first image, which reveals just a fraction of what is in space. The mosaic has a quality of 208 gigapixels and represents just 1% of the entire map; The prediction is that, in six years, more than a third of the cosmos will be mapped.
“This first piece of the map already contains about 100 million sources: stars in our Milky Way and galaxies beyond. Around 14 million of these galaxies could be used to study the hidden influence of dark matter and dark energy in the Universe”, is described in an official ESA statement.
Over the next six years, billions of data points about galaxies up to 10 billion light-years away are expected to be collected. The Euclid Space Telescope uses advanced equipment that captures images in the infrared spectrum. Furthermore, the mission seeks to unravel the nature of dark matter and dark energy.
The process of creating a ‘map’ of the universe is continuous, time-consuming and expensive. Furthermore, it would never be possible to map the entire cosmos, as there is a continuous expansion process. But in a few decades, we may have already mapped a large part of the universe.

The Cosmic Atlas: Mapping the Universe (With a Dash of Banter)
The universe, that great unfathomable expanse of chaos and cosmic wonder! It’s a bit like trying to understand why your mother-in-law insists on bringing her cat to family gatherings—bewildering and, at times, overwhelming. Despite the collective brainpower of humanity over the years, we’re still attempting to map everything around us. Yes, folks, we really are the universe’s best-kept secret.
Scientists, those brave explorers of the unknown, continue to wrestle with the essence of existence. Remember stargazing as a kid, wondering what that bright dot was? Spoiler alert: probably just a plane. But hey, there’s always a chance it’s a galactic cruiser, right?
The Grandeur of a Cosmic Atlas
Creating a cosmic ‘map’, a love letter to the universe if you will, is no small feat. Multiple teams of researchers are strapping on their interstellar boots and using various high-tech methods to attempt to chart this vast celestial real estate. Just like your GPS—but, you know, for actual stars and not just your mate’s housewarming party.
Imagine if we had a world map showing all our beloved celestial neighbors! But hold onto your telescopes, because this isn’t your average stroll in the park. Estimates suggest a staggering 400 billion stars and a whopping 100 billion planets reside in the Milky Way alone—almost makes that IKEA furniture assembly look simple by comparison.
NASA has added a delightful twist to this cosmic saga, claiming there are around 2 trillion galaxies in the observable universe. That’s about 10 times more than previously thought! I always thought my sock drawer was chaotic, but clearly, I’ve underestimated the universe’s capacity for clutter!
Wading Through the Cosmic Chaos
Now, you might ponder, “How on Earth do astronomers map all this cosmic fluff?” Well, it’s a rather intricate balancing act—like trying to dance the tango while riding a unicycle on a tightrope. One of the key hurdles is that celestial bodies are, well… continuously moving! Picture Earth doing its elegant pirouette around the Sun while a bunch of asteroids are trying to crash the party with their unpredictable trajectories. It’s a cosmic ballet gone rogue!
Thanks to the mathematical prowess of the Gaia mission, scientists are now creating an exquisitely precise map of the Milky Way. It’s the starry equivalent of a Michelin Guide—but for the entire galaxy, giving you a break from searching for the nearest good coffee shop in the ‘verse.
The Search for Order in the Cosmic Chaos
Our favorite North American astronomer, Henrietta Swan Leavitt, discovered that Cepheid variable stars could help us gauge intergalactic distances. Think of her as the ultimate cosmic road trip planner with a GPS that actually works! And our guy Edwin Hubble—cheers to him for helping us figure out redshift, a phenomenon akin to a cosmic traffic camera that helps us see how quickly celestial objects are zooming away from us.
Introducing the Euclid Space Telescope
Fast-forward to the present, and we’ve got shiny new tech in the form of the Euclid Space Telescope, freshly launched in July 2023. This bad boy’s job? Compiling a cosmic atlas that would make even the most ambitious cartographer sweat in envy. The first image released shows only 1% of what’s planned for mapping, yet manages to pack in around 100 million sources—that’s the visual equivalent of a full buffet when you were expecting just a cheeky starter!
And with predictions that in six years, we’ll map a third of the cosmos, keep your galaxy-finding apps at the ready! Just imagine—billions of data points, galaxies hidden in the fabric of space, and the quest to decode dark matter and dark energy, which, by the way, sounds like the title of a slightly mysterious conspiracy theory podcast.
Mapping the universe isn’t merely a hobby; it’s a never-ending, time-consuming extravaganza. And no, you can’t just flick a switch for instant results—this is a painstakingly slow dance through the cosmos, much like my attempts to learn the tango. One thing seems certain, though: the universe continues expanding, so we may never fully chart its entire expanse. But hey, with a bit of patience, we might just have a pretty decent map someday!
So, fellow cosmic explorers, stay tuned for further astronomical revelations, and keep your eyes on the stars. Until next time—may your adventures in stargazing be as colorful and engaging as the universe itself!
