In this episode (06-04-2026), Big Brain guides kids through three science stories: 1) Space Weather & Auroras • NOAA issued a Strong (G3) geomagnetic storm watch for June 4–5. • Kids learn how Earth’s magnetic field helps create auroras when solar particles interact with the upper atmosphere. 2) Moon + Venus Occultation • On June 17, 2026, some locations in parts of the Americas may see Venus disappear behind the Moon and reappear. • We explain “occultation” with an easy cookie-and-lamp analogy and why visibility depends on where you are on Earth. 3) Biology Discovery in Planarian Flatworms • Researchers found an unusual immune cell that releases its contents quickly to help stop germs from spreading, then vanishes within minutes. • We connect the idea to how immune systems use different “helper” cell jobs. Parent/Teacher Corner (Safety) • Never look at the Sun. • Never aim binoculars or telescopes at the daytime sky unless an adult is using certified solar filters. • For nighttime viewing, go with an adult and choose a safe, dark spot. Discussion Questions • If you could design a “science sensor” for space, what would it measure and why? • What’s one way your body protects you from germs that you can notice in real life?
