Earth from Saturn

What's that pale blue dot in this image taken from Saturn?


The robotic Cassini spacecraft
looked back toward its old home world earlier this month as it orbited

Using Saturn itself to block the
bright Sun,
Cassini imaged a faint dot on the right of the
above photograph.

That dot is expanded on the image inset, where a slight elongation in the direction of
Earth's Moon is visible.

Vast water oceans make Earth's reflection of sunlight
somewhat blue.

Earth is home to
over six billion humans
and over 100 octillion
