10 the picture shows you the home of mankind-looking at the distant blue planet in space.

Nasa's lunar orbiter 1 took the first picture of the earth from the angle of approaching the moon in 1966. Forty-two years later, NASA released this higher resolution version, which was reconstructed from similar pictures found in the original database.

"I suddenly realized that that beautiful little blue pea is the earth. I gave a thumbs-up and closed one eye. At this time, my thumb covered a planet-the earth. But I don't feel like a giant, but I feel very, very small. "

1. Voyager 1: At 7.2 million miles and 4 billion miles.

Voyager 1 took these two famous and unique photos of the earth in the distance. The first photo was taken at 1977, when Voyager 1 was 7.3 million miles away from the Earth (1 1.7 million kilometers). This is the first time in history to show a complete picture of the earth and the moon at the same time.

The second photo was taken at 1990, 4 billion miles (6.4 billion kilometers) away from the Earth, which is part of the family photo of the solar system. It shows that the earth is just a small blue spot in a beam of sunlight. This is carl sagan's immortal "light blue spot". After Sagan died, his wife Ann Deroin commented on this photo:

"We are willing to admit that the earth is indeed a small member of the vast universe. This humility is given to us by science, which urges us to abandon the self-centered psychology like children. Voyager's photo of the earth touched our hearts deeply, because you can't help thinking about how fragile our world is when you look at that photo. Think about how many people who enjoy it all have something in common; Think about the connection between everyone on this small planet. "

2. Kepler: the light in the dim starry sea

NASA's Kepler mission took a picture of the earth after flying 94 million miles (1.5 1 100 million kilometers). The reflected light in the image is so bright that a saturated light band like a sword appears on the sensor of the instrument, covering the nearby moon.

3. Cassini: Hello, goodbye.

In this beautiful snapshot, there is a point under Saturn's ring, and that is the earth. This photo was taken on 20 13. Cassini Saturn probe aimed the camera at our hometown, when thousands of people were waving from the earth. Later, before Cassini retired gloriously in 20 17, this last farewell to the earth was taken between Saturn's rings during its last lap around Saturn.

4. Lunar Reconnaissance Orbiter: "It's amazing"

"This is an amazing beauty photo! It reminds people of the famous "blue marble" of Apollo 17 astronaut jack schmitt, and that photo also highlights the African region. "

-Noah Petro, project agent scientist of NASA's Lunar Exploration Orbiter mission, said.

5. Osiris Rex: Goodbye-from now on-the speed is 654.38+0.9 million miles per hour.

As part of the engineering test, in October 20 18 65438+ 10, at a distance of 39.5 million miles (63.6 million kilometers) from the earth, NASA's Osiris asteroid detector took this photo of the earth and the moon. When the camera took this photo, the detector was moving away from our planet at a speed of10.9 million miles per hour (8.5 kilometers per second). The earth in the center of the picture is the biggest and brightest. The smaller and darker moon appears on the right. Several constellations can also be seen in the surrounding space.

6. Curiosity: Seen from Mars

A human observer with normal vision, standing on Mars, can easily see the two clear and bright "night stars" of the earth and the moon.

7. Deep space climate observatory: the strength of the moon grabs the lens.

"In 20 15, this photo taken by the satellite of the Deep Space Climate Observatory (DSCOVR) captured the unique scene of the moon passing through the bright surface of the earth. It provides an image of the back of the moon that cannot be directly observed on earth. This perspective is very touching, and such scenery can only be shared through our satellites. "

-Michael Freilich, Director of the Earth Science Department of NASA.

8. Galileo: the eighth day of departure

Eight days have passed since Galileo saw the earth for the last time-the second time he sailed to Jupiter by gravity-and when Galileo looked back at the earth, he captured the extraordinary sight of our earth and moon. This photo was taken about 3.9 million miles (6.2 million kilometers) from the Earth.

9. Rosetta: Life Pieces

In 2009, the ESA Rosetta spacecraft flew over our planet for the third and last time. During this time, it took this image about 393,000 miles (633,000 kilometers) from the Earth.

10. Messenger: Goodbye, Earth.

On August 2, 2005, Messenger, which was preparing to fly to Mercury, took several amazing images of the earth when it flew over the earth for gravity boost.

Conclusion: 10 photos of the earth taken from space.
