Although the saying "there's a great big world out there," is very true. Earth is actually incredibly small at the same time. For 20+ years NASA's Satellite Cassini has been scouring the depths of space helping us expand our knowledge of the world beyond. It is a joint Project with ESA (European Space Agency) and the Italian Space Agency.
The spacecraft reached Saturn and captured these images on April 12, 2017 at 10:41 pm PDT. Don't ask how they know this but, the part of the Earth facing Cassini at the time was the southern Atlantic ocean.
In the photo below the smaller fainter dot to the left is the moon.
The satellite is scheduled to make the first of 22 dives between Saturn and its rings today (4-26-17). With the last dive taking place on September 15th and the plan is that Cassini will destroy itself by flying straight into Saturn’s atmoshere.
