Question 1: Born on February 19, 1473, which Renaissance astronomer transformed science by arguing that Earth and the other planets orbit the Sun, most famously presented in his 1543 book De revolutionibus orbium coelestium?<br /><br />Question 2: Using a telescope in 1610, Galileo observed that a certain planet shows a full set of phases like the Moon. Which planet’s phases proved it orbits the Sun, providing powerful support for heliocentric ideas?<br /><br />Question 3: Kepler refined Copernicus’s ideas into precise laws of planetary motion. Which of Kepler’s laws states that a planet sweeps out equal areas in equal times as it orbits the Sun, revealing that planets move faster when closer to the Sun?<br /><br />Question 4: Which planet in our solar system was discovered in 1846 after mathematicians predicted its position from the strange motions of Uranus—an early triumph of physics guiding telescope discovery?<br /><br />Question 5: In 1965, two radio astronomers accidentally detected a faint glow coming from all directions in space, now seen as a baby picture of the universe. What is this signal called that provided strong evidence for the Big Bang?<br /><br /><br />You may also like <a href="https://podcasts.apple.com/us/podcast/odd-one-out/id1858563875" target="_blank" rel="noreferrer noopener">ODD ONE OUT.</a> a new podcast with Mark Ellison!  Mark gives you 4 words, you decide which word does not belong.  Three rounds daily, quick and fun,<br /><br />Portions of today's trivia podcast were made with the help of AI.
