Earth – Our Home
Pale Blue Dot is a photo of Earth that was taken by the Voyager 1 space probe in 1990 from a distance of about 6 billion kilometers (3.7 billion miles) as it was leaving our solar system. This is what Carl Sagan said about the photo: “Look again at that dot. That’s here. That’s home. That’s us. On it, everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives.

Relative Size and Distance in the Universe – Part 1
The universe is a fascinating place, mostly because of sizes and distances. The universe is inconceivably big. This is part 1 of a series I will be doing on this subject. For my first comparison, here is a photo demonstrating the relative sizes of our Sun and the planets of our solar system. You might ask, if the sun is really that much bigger than the Earth, how do we not burn up. Because, unlike this illustration, the distance to the Sun from Earth is much greater. If the Sun was the size of a basketball, the Earth, about the size of a sesame seed, would be 82 ft away.…
