NASA Study: Celestial ‘Accident’ Sheds Light on Jupiter, Saturn Riddlehttps://www.nasa.gov/missions/webb/nasa-study-celestial-accident-sheds-light-on-jupiter-saturn-riddle/An unusual cosmic object is helping scientists better understand the chemistry hidden deep in Jupiter and Saturn’s atmospheres — and potentially those of exoplanets. Why has silicon, one of the most common elements in the universe, gone largely undetected in the atmospheres of Jupiter, Saturn, and gas planets like them orbiting other stars?

What Is Aerodynamics? (Grades 5-8)https://www.nasa.gov/learning-resources/for-kids-and-students/what-is-aerodynamics-grades-5-8/This article is for students grades 5-8. Aerodynamics is the way objects move through air. The rules of aerodynamics explain how an airplane is able to fly. Anything that moves through air is affected by aerodynamics, from a rocket blasting off, to a kite flying. Since they are surrounded by air, even cars are affected by […]Apr 15, 2025 6:13 PM
