Astronomy

Study of celestial objects, space, and the physical universe.

Practical Applications

Protecting Earth from Space Hazards

Watching the Skies for Danger

Astronomy isn’t just about looking at pretty stars—it helps keep Earth safe! Astronomers track asteroids and comets that could come close to our planet. Early detection means we can prepare for, or even prevent, impacts.

How Do We Do It?

Powerful telescopes constantly scan the skies for “Near-Earth Objects.” If something big is heading our way, scientists can plan ways to deflect it or warn people in danger zones.

Real-World Impact

Monitoring space hazards is a vital part of protecting our planet and making sure we’re ready for anything out there.

Examples

  • Astronomers identified the asteroid Apophis and calculated its future paths to ensure it won’t hit Earth.

  • Space agencies run impact simulations and plan potential asteroid-deflection missions.
