Continuing the cool diagram series, here's a sequence of drawings showing the scale of the Universe. You can navigate using the links next to the title.

1 pixel = 125 km >> x5

Starting out with the Earth already a big blue marble with a pixel-thick atmosphere, the scale here is such that one pixel represents a square 125,000 metres or 0.125 megametres on the side. Some other planetary-mass objects are shown as semi-transparent circles for comparison, as well as Jupiter's famous slowly-shrinking orange anticyclone.

The Geocorona is the absolute outermost part of our atmosphere, an extremely sparse cloud of hydrogen molecules clustering around our planet due to its gravity. Earth itself casts a shadow through its atmosphere, with refraction of sunlight at the edges of that shadow causing our reddish sunrises and sunsets. The effect is exagerrated here though - the bright blue visible part of Earth's atmosphere is in reality only a couple tens of kilometres thick.

A blink of an eye lasts about a quarter of a second, during which light gets to traverse about 75,000 kilometres or 1/5th the distance to the Moon.
