Imagine looking up at the night sky as your great-great-grandparents did. They saw a breathtaking view of planets, stars, and the Milky Way—a sight that inspired countless stories and beliefs about the universe. However, today, our view of the night sky has drastically changed due to artificial lighting and urbanization. Light pollution has made the Milky Way invisible to a significant portion of the world’s population, especially in urban areas.
While rural areas might still offer a glimpse of the Milky Way, they often suffer from unreliable internet connections. People living in these areas typically pay more for slower internet speeds and limited data. Fortunately, this is changing, but it comes with a trade-off: technology is once again altering the night sky for future generations.
Over the past thirty years, internet access has transformed from a luxury to an essential part of daily life. It is crucial for finding jobs, obtaining education, and staying informed. Recognizing its importance, the United Nations Human Rights Council passed a resolution in 2016 condemning countries that deliberately interfere with internet access. However, the resolution does not require governments to provide internet access to their citizens.
In the United States, one in four households lacks internet access, often in poorer communities, making it difficult for residents to improve their circumstances. Globally, while internet usage is increasing, about 37% of the world’s population—nearly 3 billion people—remain offline. This digital divide is influenced by factors like age, race, and ethnicity, but the primary technical barrier is the cost of laying internet cables.
Connecting the remaining 3 billion people to the internet requires significant infrastructure work. One promising solution is wireless internet via satellites. Satellite internet is not new; the first satellite for internet access was launched in 2005. Initially, these satellites were placed in geosynchronous orbit, over 20,000 miles above Earth, providing wide coverage but with high latency, which affects activities like video calls and online gaming.
Recently, companies have started launching satellites into low Earth orbit, about 340 miles up. This reduces latency to levels similar to ground-based internet. However, these satellites cover a smaller area, requiring many satellites and specialized phased array antennas on Earth to provide comprehensive coverage. Phased array antennas can electronically steer signals without moving physically, enhancing connectivity.
Thanks to advancements in reusable rocket technology, satellites have become cheaper to build and launch. SpaceX, with its Starlink service, has launched over 2,000 satellites, becoming the leading satellite operator in Earth’s orbit. Other companies like OneWeb and Amazon are also planning to launch their satellite constellations. While these efforts could bridge the digital divide, they might significantly alter the night sky’s appearance.
There are environmental concerns associated with launching numerous satellites, such as greenhouse gas emissions and potential ozone layer damage. Additionally, the risk of collisions in space increases, potentially creating more debris and complicating satellite operations.
The Zwicky Transient Facility, an observatory in California, has reported a rise in satellite streaks in its images since the launch of Starlink satellites. Although the likelihood of a catastrophic asteroid hiding behind a satellite streak is low, the potential consequences are significant.
Despite these challenges, expanding internet access through satellite technology could lift millions out of poverty and enhance the visibility of human rights abuses. As the industry evolves, competition and innovation may reduce costs, making internet access more affordable for everyone.
In the future, we may no longer need to awkwardly ask for the Wi-Fi password, as seamless connectivity becomes a global reality.

When your great-great-grandparents looked up at the sky on a clear moonless night, it probably looked a lot like this. It’s the same sky their ancestors saw going all the way back to before the dawn of humanity—a spectacle of planets, stars, and nebulae, along with a vast hazy streak that the ancient Greeks named the Milky Way.
It’s hard to overstate how profoundly the night sky shaped our ancestors’ beliefs about space, time, and the meaning of life. All over the world, in every culture, people created elaborate stories to explain what these thousands of little spots of light were and how they got there.
Then it all started to change as artificial lighting began to wash out our view of the night sky. For many people today, the night sky looks completely different from what their ancestors saw. Increasing urbanization and resulting light pollution have made the Milky Way no longer visible to one-third of the world’s population—four out of every five North Americans and three out of every five Europeans. If you can see the Milky Way at night, there’s a good chance you’re in a rural area far from a major city.
However, if you’re in a rural area, there’s also a good chance that your internet connection isn’t very reliable, if it exists at all. Compared to people living in cities, you might be paying more for lower speeds and less data. The good news is that this is changing. The bad news is that once again, technology will make the night sky look completely different for future generations.
Over the past three decades, having an internet connection has shifted from being a luxury to a necessity. Without it, many of us wouldn’t be able to find jobs, get an education, or stay informed about our communities or the world at large. That’s why in 2016, the United Nations Human Rights Council passed a resolution condemning countries that deliberately interfered with people’s internet access. However, the resolution doesn’t state that governments must provide internet access to their citizens, only that they can’t take it away from those who already have it.
In the United States, one in four households lack internet access, often located in poorer communities, making it even harder for residents to get ahead. Globally, the number of internet users is rising sharply, but about 37 percent of the world’s population—nearly 3 billion people—are still offline. This digital divide can be attributed to factors like age, race, and ethnicity, but from a technical standpoint, the access gap is largely due to the cost of laying internet cables.
Laying cable is expensive, especially for the so-called “last mile” between the local internet service provider and a person’s home. In some parts of the United States, internet service providers charge homeowners tens of thousands of dollars to establish a broadband connection. Connecting those remaining 3 billion people will require significant infrastructure work, but is it possible to skip the cables and deliver the internet wirelessly?
One common method is via satellite. Satellite internet is not new; the first satellite designed to provide internet access was launched in 2005, and many more followed. The first generation of internet satellites were launched into geosynchronous orbit, over 20,000 miles above the Earth’s surface. These satellites can communicate continuously with ground stations over a third of the planet, but this comes at a cost. It takes about a quarter of a second for the signal to make the round trip from the Earth to the satellite and back, resulting in latency that can be problematic for activities like video calls and online gaming.
In recent years, companies have begun launching internet satellites into low Earth orbit, around 340 miles up. This allows for lower latency, similar to ground-based internet, but at this altitude, a satellite can only see a small portion of the Earth’s surface. To provide wider coverage, many satellites and receivers on Earth are needed. Each subscriber will likely need a specialized phased array antenna to access the network of moving satellites.
Phased array antennas can electronically steer signals without physically moving the antenna. In recent years, satellites have become cheaper to build and launch, thanks in part to reusable rocket technology. The number of satellites launched each year has increased dramatically, with over 2,000 launched in the past two years alone, primarily by SpaceX for its Starlink service.
Since launching its first batch of 60 Starlink satellites in May 2019, SpaceX has become the predominant satellite operator in Earth’s orbit. Of the nearly 5,000 operating satellites today, about 2,000 are Starlink satellites, and the company plans to launch many more. However, many astronomers are concerned about the impact of these satellites on astronomical observations, as they can reflect light and interfere with telescope images.
SpaceX is working to reduce the glare from its satellites, but it is not the only company launching broadband satellites. Other companies, such as OneWeb and Amazon, are also planning to launch their own satellite constellations. While these tens of thousands of satellites could help close the digital divide, they could also alter the appearance of the night sky significantly.
There are potential environmental impacts associated with launching so many satellites, including greenhouse gas emissions and damage to the ozone layer. Additionally, the risk of collisions in space increases with more satellites, which could create more debris and further complicate satellite operations.
The Zwicky Transient Facility, an observatory in California, has reported that the number of satellite streaks in its images has increased significantly since the launch of Starlink satellites. While the chances of a planet-killing asteroid hiding behind a satellite streak are small, the potential consequences are significant.
Despite the potential downsides, the expansion of internet access through satellite technology could lift millions out of poverty and ensure visibility of human rights abuses. Overall, efforts to send more satellites into orbit to improve internet accessibility are likely worthwhile, provided that everyone can afford access.
As the industry evolves, hopefully, competition and time will help bring down costs, leading to a future where no one has to awkwardly ask for the Wi-Fi password again.
