The "Pale Blue Dot" and Our Place in the Universe

In 1990, when Voyager I spacecraft was leaving the solar system, NASA commanded the robotic space probe to turn its camera towards Earth and take a picture of the planet. The picture, taken from a distance of 6 billion kilometers, came to be known as “the pale blue dot”. Viewed from such a remote vantage point, our planet seemed to be an insignificant dot against the vastness of space.

The two videos that I selected for this post deal with different facets of this apparent insignificance when it comes to understanding our place in the universe. Both approaches are very interesting.
