Nuclear Explosions Could Redirect Asteroid Threats to Earth

---

Summary: A new study by U.S. scientists suggests that nuclear explosions could be used to redirect dangerous asteroids away from Earth. By detonating a nuclear warhead at a distance of over a mile from an asteroid, researchers propose that a burst of X-rays could alter its trajectory, avoiding the fragmentation risks depicted in movies like Armageddon. The study utilized a mock asteroid in a vacuum environment to test this concept, highlighting the need for precision to ensure the asteroid is redirected without breaking into harmful pieces. This innovative approach could revolutionize planetary defense strategies against asteroid threats.

A groundbreaking study from scientists in the United States has unveiled a potential strategy for averting catastrophic asteroid impacts on Earth. According to a report by The Guardian, researchers suggest that detonating a nuclear warhead at a distance greater than one mile from an asteroid’s surface could effectively redirect its trajectory by emitting a burst of X-rays. This innovative approach stands in stark contrast to the dramatic methods portrayed in Hollywood films like *Armageddon* and *Deep Impact*, where nuclear devices are used to obliterate asteroids, resulting in a perilous field of dangerous fragments heading toward our planet.

The concept introduced in the study is termed “X-ray scissors.” In a controlled environment, scientists created a mock asteroid, weighing approximately a tenth of a gram and composed of silica, and released it into a vacuum space. Researcher Moore explained the experimental setup: “It was a novel idea. A mock asteroid is suspended in space. For a one-nanometer fall, we can effectively ignore Earth’s gravity for 20 millionths of a second, allowing us to unleash a burst of X-rays that sweep over the mock asteroid’s surface, which is about 12.5 millimeters across—approximately the size of a finger.”

The study emphasizes the need for precision in this method. Moore elaborated, “The trick is to apply just enough force to redirect the incoming asteroid without breaking it into multiple fragments that could still threaten Earth.” This careful balance could be pivotal in preventing future asteroid-related disasters, as it addresses the inherent risks associated with fragmenting an asteroid, which may result in even greater dangers than the original threat.

While the concept is still in the experimental stage, the implications of this research could be transformative for planetary defense strategies. As scientists continue to explore this method, it opens up new avenues for protecting our planet from potential asteroid collisions, shifting the narrative from sheer destruction to strategic redirection.
