In this episode, we’ll explore these intelligent, playful marine mammals known for their friendliness and incredible behaviours. Learn how dolphins, part of the “toothed whale” family alongside orcas, differ from their close relatives and porpoises, and discover what makes them such clever and curious ocean dwellers.

In this episode, we're answering your questions! We'll learn why some animals use poop to build their homes—and whether it smells terrible, explore why cars need gas and oil, the science behind rising muffins, the importance of math, and why hair turns gray as we age. We'll also take a look at why siblings can sometimes be annoying, touching on psychology and life skills. Plus, we've sprinkled in surprising facts about gasoline, muffins, and even some quirky poop trivia to keep things interesting. So whether you're in bed, in the car, or enjoying some quality science time, let's jump into our first question!

In this episode, we'll journey through our home galaxy, the Milky Way, a vast spiral galaxy with over 100 billion stars, including our Sun. Located in the quieter Orion-Cygnus Arm, about 27,000 light-years from the center, our solar system orbits far from the powerful supermassive black hole, Sagittarius A*, which holds the galaxy together. We'll explore the three main types of galaxies—spiral, elliptical, and irregular—and imagine the technology that might one day let us travel beyond the Milky Way. Finally, we'll consider one of science's biggest mysteries: Are we alone in the galaxy? We'll learn how scientists search for life on planets in the "Goldilocks Zone," keeping us curious about what—and who—might be out there.
