Every Visible Star in the Night Sky, in One Map
View the high resolution version of this incredible map by clicking here.
The stars have fascinated humanity since the beginning of civilization, from using them to track the different seasons, to relying on them to navigate thousands of miles on the open ocean.
Today, travelers trek to the ends of the Earth to catch a glimpse of the Milky Way, untouched by light pollution. However, if you’re in the city and the heavens align on a clear night, you might still be able to spot somewhere between 2,500 to 5,000 stars scattered across your field of vision.
This stunning star map was created by Eleanor Lutz, under the Reddit pseudonym /hellofromthemoon, and is a throwback to all the stars and celestial bodies that could be seen by the naked eye on Near Year’s Day in 2000.
Star Light, Star Bright
Stars have served as a basis for navigation for thousands of years. Polaris, also dubbed the North Star in the Ursa Minor constellation, is arguably one of the most influential, even though it sits 434 light years away.
Because of its relative location to the Earth’s axis, Polaris is reliably found in the same spot throughout the year—on this star map, it can be spotted in the top right corner. The Polynesian people famously followed the path of the North Star, along with wave currents, in all their way-finding journeys.
Interestingly, Polaris’ dependability is why it is commonly mistaken as the brightest star, but Sirius actually takes that crown—find it below the Gemini constellation, at the 7HR latitude and -20° longitude coordinates on the visualization. Located in the Canis Majoris constellation, Sirius burns bluish-white, and is one of the hottest objects in the universe with a surface temperature of 17,400°F (9,667°C). Sirius is nearly 40 times brighter than our Sun.
The Egyptians associated Sirius with the goddess Isis, and used its location to predict the annual flooding of the Nile. This also isn’t the only way humans have used visible stars to “predict” the future, as evidenced by the ancient practice of astrology.
Seeking Answers in the Stars
In the star map above, the orange lines denote the twelve signs of the Zodiac, each found roughly along the same band from 10° to -30° longitude. These Zodiac alignments, along with planetary movements, form the basis of astrology, which has been practiced across cultures to predict significant events. While the scientific method has widely demonstrated that astrology doesn’t hold much validity, many people still believe in it today.
The red lines on the visualization signify the constellations officially recognized by the International Astronomical Union (IAU) in 1922. Its ancient Greek origins are recorded on the same map as the blue lines, from which the modern constellation boundaries are based. Here’s a deeper dive into all 88 IAU constellations:

Into the Depths of Deep Space
The quirk of naming stars after flora and fauna doesn’t end there. Our night sky also reveals visible galaxies, nebulae, and clusters far, far away—but they’re named after familiar birds, natural objects, and mythical creatures. See if you can find some of these interesting names:
- Open Cluster: Wild Duck Cluster
- Open Cluster: Eagle Nebula
- Open Cluster: Beehive Cluster
- Open Cluster: Butterfly Cluster
- Emission Nebula: North American
- Emission Nebula: Trifid Nebula
- Emission Nebula: Lagoon Nebula
- Emission Nebula: Orion Nebula
- Open Cluster with Emission Nebula: Swan Nebula
- Open Cluster with Emission Nebula: Christmas Tree Cluster
- Open Cluster with Emission Nebula: Rosette Nebula
- Globular Cluster: Hercules Cluster
There’s an interesting concentration of unnamed open and globular clusters just above the Sagittarius constellation, between 18-20HR latitude and -20° to -30° longitude. Another one can be seen next to Cassiopeia, just below Polaris between 1HR-3HR latitude, at 60° longitude. The only two visible spiral galaxies, Andromeda and Pinwheel, are located close between 0-2HR latitude and 30°-40° longitude.
The Relentless Passage of Time
We now know that the night sky isn’t as static as people used to believe. Although it’s Earth’s major pole star today, Polaris was in fact off-kilter by roughly 8° a few thousand years ago. Our ancestors saw the twin northern pole stars, Kochab and Pherkad, where Polaris is now.
This difference is due to the Earth’s natural axial tilt. Eight degrees may not seem like much, but because of this angle, the constellations we gaze at today are the same, yet completely different from the ones our ancestors looked up at.

How Much Student Debt Does Each State Hold?
Crippling student debt in the U.S. has reached a record high of $1.5 trillion nationwide. Today’s map breaks down which states bear the highest burden.
How Much Student Debt Does Each State Hold?
Education may be priceless, but the costs of obtaining it are becoming steeper by the day.
Almost half of all university-educated Americans rely on loans to pay for their higher education, with very few graduating debt-free. Total U.S. student debt has more than doubled in the last decade—reaching a record high of $1.5 trillion today.
Today’s data visualization from HowMuch.net breaks down the average student debt per capita, to uncover which states shoulder the highest burden in this growing crisis.
Students are Paying Through the Nose
Before diving into the graphic, let’s take a quick look at why student debt is racking up. The ballooning costs to attend college today compared to thirty years ago is one driving factor.
Source: The College Board 2018 report.
What’s more, these figures don’t include the expenses for accommodation and other supplies, which can add another $15,000-$17,000 per year.
The United States of Student Debt
In the state map above, it’s immediately obvious that Washington D.C. tops the list. While the nation’s capital is the most educated metropolitan area in the country, it also suffers from $13,320 in student debt per capita.
At approximately 147% above than the national average of $5,390, Washington D.C.’s debt burden per capita is almost double that of the state in second place. Georgia comes in with $7,250 debt per capita, 34.5% above the national average.
|State||Student Debt per Capita||Difference from Average|
|District Of Columbia||$13,320||147.1%|
Rounding out the five states with the most student debt per capita are Maryland, Minnesota, and Ohio, in that order. On the flip side, Wyoming has the least debt per capita ($3,610), which is 33.0% lower than the national average. Hawaii follows right behind at $3,780, and 29.9% below the national average.
Interestingly, a growing population on the West Coast helps to lower the debt burden for states like California, even despite the strong presence of prestigious schools. Home to Stanford, USC, UCLA, CalTech, and more, the Golden State surprisingly only has $4,530 in debt per capita.
The Last Straw?
Today’s Americans are more educated than ever before, but the sticker shock is causing some whiplash. This overall trend of spiraling student debt has significant implications on a person’s life trajectory. With many graduates unable to repay their loans on time, more of them are delaying major life milestones, such as starting a family or becoming a homeowner.
In efforts to curb this crisis, many 2020 presidential hopefuls have already started proposing plans to cancel or forgive student debt—with close attention on mid- to low-income households that would benefit the most from reduced loans.
The History of the World, in One Video
This epic attempt to condense the history of the world — including the rise and fall of empires — fits into a single video.
Throughout the history of the world, many civilizations have risen and fallen.
You may be familiar with the achievements of prominent societies like the Romans, Mongols, or Babylonians, but how do all of their stories intertwine over time and geography?
Visualizing the History of the World
Today’s video comes to us from Ollie Bye, and it attempts to integrate the histories of all major civilizations known by historians into a single, epic video.
Similar to the Histomap, it’s pretty much impossible for a video like this to be perfect due to biases and a general lack of data. However, it’s still a compelling attempt at showing global history in a short and sweet fashion.
Let’s look at some specific moments on the video that particularly stand out.
750 AD: The Umayyad Caliphate
One of the largest empires in history, the Umayyad Caliphate peaked sometime around 750 AD.
Conquering most of North Africa, the Middle East, and even parts of Europe (including modern-day Spain, Portugal, and France), the Umayyads commanded a formidable territory with an area of 11,100,000 km² (4,300,000 sq. mi) and encompassing 33 million people.
1279: Mongol Dominance
No history of the world is complete without a mention of the Mongols.
Nearby societies have always been on edge when nomadic tribes in the Eurasian Steppe entered into organized confederations. Similar to the Huns or various Turk federations, the Mongols were known for their proficiency with horses, bows, and tactics like the feigned retreat.
Under the leadership of Temüjin — also known as Genghis Khan — the Mongols conquered one of the largest empires by land.
The empire reached its greatest extent just two years after the death of Genghis Khan.
Later on, it fragmented into smaller empires that were also quite notable in the context of world history. For example, Kublai Khan — the grandson of Genghis Khan — even went on to begin the influential Yuan Dynasty in China.
1346: The Black Death
The video also shows other vital stats, such as an estimate of global population through the ages.
In the mid-14th century, you can see this number take a rare U-turn, as millions of people die from the infamous and deadly Bubonic Plague.
The Black Death — one of the most devastating pandemics in the history of the world — hit Europe in 1346, and it eventually killed 30-60% of the continent’s population. There is no exact figure on the final death toll, but historians estimate it to be somewhere between 75 and 200 million people throughout Eurasia.
1418: The Age of Discovery
The video also provides a 10,000-foot view of the Age of Discovery, a period of time in which European powers explored the world’s oceans.
This colonial period marks the beginning of globalization, creating wide-ranging impacts that set the stage for more modern history.
In the video, it’s possible to see European colonies develop in all parts of the world, as well as how they eventually morphed into the countries that dot the globe today.
Playing the History Game
While it is certainly ambitious, not everyone will agree that this is a successful attempt at portraying world history – even in the limited scope of time allotted.
One key detail that seems to be missing, for example, is showing the development of the indigenous societies that existed in North America for thousands of years. That said, it’s also not clear what data and records are available to show these maps over many centuries of time.
Despite the possible flaws, the video does pack a lot of information into a short period of time, creating a compelling opportunity for learning and discussion. Like the Histomap, it may not be a definitive history of the world – but instead, it’s a useful attempt that stimulates our appetite for more information about the world and the societies that inhabit it.
