It abruptly struck me that that tiny pea, fairly and blue, was the Earth. I put up my thumb and shut one eye, and my thumb blotted out the planet Earth. I didn’t really feel like a large. I felt very, very small.

1. Voyager 1: At 7.2 million miles … and 4 billion miles
Voyager famously captured two distinctive views of our dwelling world from afar. The upper image, taken in 1977 from a distance of seven.3 million miles (11.7 million km), confirmed the total Earth and full moon in a single body for the primary time in historical past.
The second picture, taken in 1990 as a part of a household portrait of our solar system from 4 billion miles (6.4 billion km), reveals Earth as a tiny blue speck in a ray of daylight. This is the famous “Pale Blue Dot” image immortalized by Carl Sagan.
Sagan’s widow, Ann Druyan, stated of the picture:
This was our willingness to see the Earth as a 1-pixel object in a far larger cosmos. It’s that humility that science offers us. That weans us from our childhood have to be the middle of issues. And Voyager gave us that picture of the Earth that’s so coronary heart tugging as a result of you may’t take a look at that picture and never consider how fragile, how fragile our world is. How a lot we have now in frequent with everybody with whom we share it; our relationship, our relatedness, to everybody on this tiny pixel.
2. Kepler: A brilliant flashlight in a darkish sea of stars
NASA’s Kepler mission captured Earth’s image because it slipped previous at a distance of 94 million miles (151 million km). The reflection was so terribly brilliant that it created a saber-like saturation bleed throughout the instrument’s sensors, obscuring the neighboring moon.
3. Cassini: Hey and goodbye
This beautiful shot of Earth as a dot beneath Saturn’s rings was taken in 2013 as hundreds of people on Earth waved on the actual second the Cassini spacecraft pointed its cameras at our dwelling world. Then, in 2017, Cassini caught this final view of Earth between Saturn’s rings because the spacecraft spiraled in for its Grand Finale at Saturn.
4. Lunar Reconnaissance Orbiter: “Merely gorgeous”
The image is simply stunning. The picture of the Earth evokes the well-known Blue Marble picture taken by astronaut Harrison Schmitt throughout Apollo 17 … which additionally confirmed Africa prominently within the image.

5. OSIRIS-REx: Goodbye – for now – at 19,000 mph
As a part of an engineering take a look at, NASA’s OSIRIS-REx spacecraft captured this picture of Earth and the moon in January 2018 from a distance of 39.5 million miles (63.6 million km). When the digital camera acquired the picture, the spacecraft was shifting away from our dwelling planet at a velocity of 19,000 miles per hour (8.5 km per second). Earth is the most important, brightest spot within the middle of the picture, with the smaller, dimmer moon showing to the fitting. A number of constellations are additionally seen within the surrounding space.
6. Curiosity: The view from Mars
A human observer with regular imaginative and prescient, standing on Mars, could easily see Earth and the moon as two distinct, brilliant “night stars.”
7. DSCOVR: Moon photobombs Earth
This picture from the Deep Area Local weather Observatory (DSCOVR) satellite captured a unique view of the moon as it moved in front of the sunlit side of Earth in 2015. It supplies a view of the far side of the moon, which is rarely straight seen to us right here on Earth. I discovered this attitude profoundly shifting and solely via our satellite views may this have been shared.

8. Galileo: 8 days out
Eight days after its remaining encounter with Earth – the second of two gravitational assists from Earth that helped enhance the spacecraft to Jupiter – the Galileo spacecraft regarded again and captured this outstanding view of our planet and its moon. The picture was taken from a distance of about 3.9 million miles (6.2 million km).
9. Rosetta: A slice of life
Earth from about 393,000 miles (633,000 km) away, as seen by the European Area Company’s comet-bound Rosetta spacecraft throughout its third and remaining swing-by of our dwelling planet in 2009.
10. MESSENGER: So lengthy
The Mercury-bound MESSENGER spacecraft captured several stunning images of Earth throughout a gravity help swing-by of its dwelling planet on August 2, 2005.
