When one celestial object passes in front of another, it can cast a shadow that travels across space – and sometimes across Earth. These moments of alignment, known as eclipses, occultations, and transits, allow scientists to study distant objects in remarkable ways. By observing how light changes when an object briefly blocks another, astronomers can measure sizes and shapes, detect atmospheres, and refine the orbits of asteroids and planets.

Career Spotlight: Welder (Ages 14-18)
What does a welder do? A welder uses tools that join two or more parts through forces such as heat or pressure. Metals are the materials most commonly used in welding, but it’s also possible to weld thermoplastics or wood. Welders use their hands, skills, and problem-solving abilities to create something new. At NASA, welders […]
