10 The Large Hadron Collider (CERN)

The Large Hadron Collider, buried beneath the Franco-Swiss border near Geneva, is the most powerful particle accelerator on Earth. Operated by CERN (the European Organization for Nuclear Research), the collider stretches over 17 miles (27.3 km) in circumference, using superconducting magnets cooled to -455.8°F (-271°C) to smash particles together at near-light speeds. The facility’s primary goal is to probe the universe’s fundamental structure, studying particles that exist for just billionths of a second.

The LHC’s creation and continued operation rely on collaboration from over 100 countries, including the United States, China, Russia, India, and all major European nations. Each contributed components, researchers, and funding—creating an international workforce of more than 10,000 scientists and engineers.

It was here in 2012 that scientists confirmed the existence of the Higgs boson, a particle predicted decades earlier but never observed. The data processing needs alone required a globally distributed computing grid just to analyze the petabytes of information produced daily.^[1]

9 The International Space Station (ISS)

Floating 250 miles (402 km) above Earth at (28,163 km/h), the ISS is a modular space station and research hub that’s been continuously inhabited since 2000. Its construction and maintenance are shared by five major space agencies—NASA (USA), Roscosmos (Russia), ESA (Europe), JAXA (Japan), and CSA (Canada)—with over 20 additional countries contributing components or research.

Each agency provided specific systems: Russia’s modules handle propulsion and docking, Europe’s Columbus lab hosts life sciences and microgravity research, Japan’s Kibo module includes an external science platform, and Canada’s robotic arm, Canadarm2, services visiting cargo spacecraft. The ISS has hosted over 270 astronauts from 21 nations, and missions aboard it have conducted groundbreaking research in medicine, biology, physics, and climate science. It was assembled in orbit from dozens of separate modules, launched over a decade from different countries’ rockets.^[2]

8 The Chernobyl Sarcophagus and New Safe Confinement Dome

After Reactor 4 exploded at the Chernobyl Nuclear Power Plant in 1986, the Soviet Union hastily constructed a concrete sarcophagus to contain the radioactive wreckage. By the early 2000s, the structure was crumbling and leaking radiation, threatening a second ecological catastrophe. In response, more than 40 countries joined to fund and build a new containment structure known as the New Safe Confinement (NSC).

The project, managed by the European Bank for Reconstruction and Development (EBRD), culminated in 2016 with the placement of a steel arch weighing 36,000 tons (32,658 metric tons) and spanning over 843 feet (257 m). Built nearby and then slid into place using hydraulic systems, the structure is the largest movable land-based object ever constructed. It includes robotic cranes and radiation shielding systems for safely dismantling the remains of Reactor 4 and was funded by global donors, including Japan, the U.S., Canada, Germany, and the EU.^[3]

7 The Human Genome Project

In 1990, scientists from around the world launched one of the most ambitious biological projects in history: to map the entire human genome. The Human Genome Project (HGP) was led by the United States National Institutes of Health but quickly expanded into a global research initiative involving the United Kingdom, Japan, France, Germany, and China. The goal was to identify and map all 20,000–25,000 human genes, sequencing the three billion DNA base pairs that comprise the human blueprint.

It took 13 years and cost over $3 billion, but by 2003, the project had achieved its goal. International teams divided up chromosomes and sequence assignments, publishing results in real time so scientists across borders could verify and compare. China, for example, sequenced chromosome 3, while the UK’s Sanger Centre handled chromosome 1.

The HGP laid the foundation for modern genetics, paving the way for gene therapy, personalized medicine, and rapid COVID-19 vaccine design. The project also pioneered open-access data sharing across countries, helping reshape global scientific norms.^[4]

6 The Global Positioning System (Modern GPS Collaboration)

GPS began as a U.S. Department of Defense system in the 1970s, originally limited to military use. But today’s navigation systems are vastly more complex and globally integrated, thanks to partnerships between multiple spacefaring nations. Devices now pull location data not only from U.S. GPS satellites but also from Russia’s GLONASS, Europe’s Galileo, China’s BeiDou, and support systems from India and Japan.

Smartphones and aircraft use multi-constellation receivers, which improve accuracy, redundancy, and coverage worldwide. Creating this compatibility required international agreements on signal standards, satellite frequencies, and data-sharing protocols. Europe’s Galileo network, for instance, cost over €10 billion and was built to reduce dependency on American systems. The result is a real-time, high-precision global network that works for billions of users—whether they’re navigating city traffic or guiding rescue drones through disaster zones.^[5]

5 ITER (International Thermonuclear Experimental Reactor)

ITER, currently under construction in southern France, is the most ambitious attempt yet to make nuclear fusion a reality. Unlike fission reactors, which split atoms and generate radioactive waste, fusion mimics the Sun’s energy production, combining hydrogen isotopes to produce enormous energy with minimal environmental impact. The project is backed by 35 nations, including the European Union, the United States, Russia, China, India, South Korea, and Japan. It’s one of the most expensive and complex energy projects ever attempted.

The facility will house the largest tokamak reactor in the world, capable of withstanding temperatures over 270 million degrees Fahrenheit (150 million degrees Celsius). Building it has required a globally coordinated supply chain: Japan makes superconducting magnets, India builds cooling systems, the EU contributes the cryostat, and the U.S. supplies diagnostic equipment. The reactor is so massive that parts must be shipped in gigantic custom-built transports and assembled on-site like a jigsaw puzzle. No single country had the resources or expertise to build this alone.^[6]

4 The Square Kilometre Array (SKA)

The Square Kilometre Array will be the largest radio telescope system on Earth, with antenna arrays spread across South Africa and Australia and hosted by an alliance of over a dozen countries, including China, India, the Netherlands, the UK, Canada, and Italy. The SKA will be powerful enough to detect signals from just after the Big Bang, map dark matter, and potentially spot alien civilizations by capturing faint radio waves across space.

The SKA’s distributed design will include hundreds of thousands of low-frequency antennas in Western Australia and hundreds of dish antennas in South Africa, working together as a single, massive instrument. The project is building an entirely new high-speed global computing infrastructure to support its operations, processing over 600 petabytes of data per year. International partners are contributing not just funding but also custom software systems, hardware, and even remote data analysis nodes that span the globe.^[7]

3 The Global Ocean Observation System (GOOS)

Monitoring the oceans—a vast, ever-changing system that covers over 70% of the planet—is impossible for any single nation to manage. That’s why countries joined forces to create GOOS, the Global Ocean Observing System, coordinated by UNESCO and supported by over 100 countries and research institutions. It combines satellites, underwater robots, floating buoys, and shoreline stations to measure everything from sea temperature and salinity to plankton blooms and tsunami waves.

Thousands of autonomous devices like Argo floats drift through the oceans, transmitting data via satellite to servers in Europe, the U.S., Australia, and Japan. Nations cooperate on shared standards for ocean data collection and analysis, which allows meteorologists to forecast hurricanes, fisheries to track ecosystems, and climate scientists to model sea-level rise. The network’s success depends entirely on real-time international sharing of marine data—something no other Earth system has managed at this scale.^[8]

2 The James Webb Space Telescope (JWST)

Launched in December 2021, the James Webb Space Telescope is the most advanced space observatory ever built—and it exists only because of an international partnership between NASA (USA), ESA (Europe), and CSA (Canada). It orbits at Lagrange Point 2, nearly a million miles (1.6 million km) from Earth, shielded from solar radiation by a five-layer sun shield the size of a tennis court. JWST can detect infrared light from the earliest galaxies, allowing scientists to see farther back in time than ever before.

ESA provided the launch on an Ariane 5 rocket, as well as two major scientific instruments. Canada supplied the Fine Guidance Sensor that keeps the telescope precisely aligned. The mission involved over 10,000 scientists and engineers across three continents. It relied on shared engineering challenges, such as folding mirror segments, cryogenic cooling systems, and heat-resistant shielding, none of which had ever been used in space before. Without the pooled expertise and budgets of three space agencies, JWST wouldn’t have gotten off the ground.^[9]

1 The COVID-19 Vaccine Rollout and COVAX

When the COVID-19 pandemic struck, the global scientific community mounted a response at unprecedented speed—and it wasn’t just one country’s effort. While multiple vaccines were developed in different nations—Pfizer (USA), BioNTech (Germany), Oxford-AstraZeneca (UK), Sinovac (China), and Sputnik V (Russia)—their creation and distribution relied on global clinical trials, shared virus sequencing, and multinational supply chains.

The COVAX initiative, launched by Gavi, the WHO, and CEPI, aimed to distribute vaccines equitably to low- and middle-income countries, coordinating logistics across continents. Even vaccine production was international: Pfizer’s vaccine was manufactured across the U.S., Belgium, and Germany, with lipids sourced from Asia and vials from the EU. Many nations shared mRNA technology, trial data, and regulatory expertise in real-time to get the first shots into arms within a year of the outbreak—a timeline previously considered impossible.^[10]
