Neil deGrasse Tyson’s “Most Astounding Fact”:

“When I look up at the night sky, and I know that, yes, we are part of this Universe, we are in this universe, but perhaps more important than both of those facts is that the universe is in us. When I reflect on that fact, I look up — many people feel small, ’cause they’re small and the universe is big, but I feel big, because my atoms came from those stars.”

Star Size Comparisons

Explanation: How big is our Sun compared to other stars? In a dramatic and popular video featured on YouTube, the relative sizes of planets and stars are shown from smallest to largest. The above video starts with Earth’s Moon and progresses through increasingly larger planets in our Solar System. Next, the Sun is shown along as compared to many of the brighter stars in our neighborhood of the Milky Way Galaxy. Finally, some of the largest stars known spin into view. Note that the true sizes of most stars outside of the Sun and Betelgeuse are not known by direct observation, but rather inferred by measurements of their perceived brightness, temperature, and distance. Although an inspiring learning tool that is mostly accurate, APOD readers are encouraged to complete the learning experience — and possibly help make future versions more accurate — by pointing out slight inaccuracies in the video.
