Space data centers could end stargazing as we know it
Sprawling networks of space data centers could make it nearly impossible for humans to stargaze. That's just one of the many risks that come with placing tens of thousands of AI computers into orbit, according to a new report. Why it matters: Most Americans don't want data centers built near them, but putting them in space brings a new set of problems. Threat level: "Companies and policymakers…
Tens of thousands of AI-powered computers orbiting the Earth pose a significant threat to stargazing, according to a new report. This development raises concerns among astronomers and policymakers who are wary of the consequences. The Innovation for Cool Earth Forum, an annual event hosted by the Japanese government, published the report, which highlights the risks associated with space data centers.
The presence of hundreds of thousands of these data centers in orbit could obscure the most visible points of light in the night sky, making stars nearly invisible to the naked eye. Moreover, the potential for collisions and the generation of space debris pose further risks to both space data centers and Earth's natural environment. These orbiting systems, powered by solar energy, rely on numerous rocket launches, contributing to greenhouse gas emissions and black carbon pollution.
Industry experts and researchers warn that the rapid proliferation of space data centers may lead to unforeseen consequences. According to a recent report, investments in orbital data centers reached $197 million in 2025 and have soared to $1.11 billion this year, despite the potential risks. Major players like SpaceX, Starcloud, and Blue Origin have expressed ambitions to deploy thousands of data center satellites, which could create a constant stream of satellites traversing the Earth at speeds of 17,000 miles per hour.
While many investors remain optimistic about the prospects of space data centers, researchers caution that a cautious approach is necessary. Lead author of the report, Columbia University's David Sandalow, emphasizes the need for careful consideration and management of the risks associated with space data centers. He urges a slower, more deliberate rollout to mitigate potential harm to stargazing and the broader environment.
The report serves as a stark reminder that as technology advances, it is crucial to weigh the benefits against the potential drawbacks. As governments and companies continue to invest in space data centers, they must ensure that these innovations are developed and deployed responsibly, with a thorough understanding of the implications for humanity and the cosmos.
