It's not often that some event comes along to really show humanity its true place in the universe, but two NASA spacecraft have just managed just that.

I'm talking, of course, about the spectacular NASA photos of Earth as it appeared from Saturn —nearly 900 million miles away (1.4 billion kilometers) —as well as a photo of our planet as it appeared from Mercury, nearly 61 million miles (98 million km) distant. NASA took the photos Friday (July 19) using the Cassini spacecraft around Saturn and the Messenger spacecraft around Mercury as part of a global campaign to show the world how the solar system views our planet Earth. The space agency even worked to coordinate campaigns to involve space fans by having them wave at Saturn. The images, by far, are amazing. Earth and its moon stand out as bright pinpricks of light in Messenger's view from Mercury, while our planet is a pale, fuzzy dot nestled between Saturn's rings in the Cassini view.

This rare image taken on July 19, 2013, by NASA's Cassini spacecraft has shows Saturn's rings and our planet Earth and its moon in the same frame. At the time, Cassini was 2013 from a distance of about 898.414 million miles (1.445858 billion kilometers) from Earth. It is only one footprint in a mosaic of 33 footprints covering the entire Saturn ring system (including Saturn itself) taken by Cassini's wide-angle camera. (Image credit: NASA/JPL-Caltech/Space Science Institute)From my perspective, the images accomplish two things: First, it seems like a technological marvel of orbital mechanics and photography to be able to coordinate two different spacecraft in orbit around two different planets (and controlled by different science teams) to photograph yet a third planet in between them. What's more, this is not the first time Cassini and Messenger have snapped photos of Earth from their respective planets. Cassini has done it a couple of times, and Messenger took a portrait of the solar system from Mercury in 2011. Second, the photos clearly do what they were intended to do— show the world exactly where Earth stands in the universe. You, and everyone you know and have ever known, live on a tiny island of a planet in the vast sea of the universe. As the "Star Trek" warp drive inventor Zephram Cochrane explained when he first saw Earth from deep space, "It's so small." And that is where we live, on a small world —a "pale blue dot," as famed astronomer Carl Sagan once put it. This is our home, this island Earth. [See more photos of Earth from Saturn and Mercury]

So what do you think of Cassini and Messenger's view of Earth from Saturn and Mercury? Has it given you a new sense of perspective? Or are they just more photos from old space probes retasked into a publicity stunt?
