The Earth remains the only home of humanity in all the universe and the only planet we know capable of supporting human beings. Today, Earth Day, it is more important than ever to enjoy it.
NASA / Expedition 7
With the advent of rockets and spaceflights, our cosmic perspective has changed forever.
The very first image of Earth seen from space, where the Karman line (the original definition of space) was crossed, appeared in 1945. Three years later, it was possible to realize flights long enough and tall enough to assemble a mosaic like this, revealing the curvature and many details on the surface of the Earth.

Even amateurs can reach such highs with a limited budget.
Today, you can venture high enough to photograph the curvature of the Earth at a cost of only $ 150 (and with a camera much better than the one available in the 1940s) if you are a type of handyman. The photo here comes from a 2009 MIT student project.

From the low Earth orbit, astronauts on the International Space Station have the best views of the Earth.
To date, the human presence in space, aboard the International Space Station, has been constant for 18 years and 171 days. It is the longest sequence of this type in the history of our species.

Sleeping and active volcanoes reveal the prevailing winds of our planet.
The volcanic ash of the erupting summit blackens the snow at the top not only of the erupting mountain, but also of its nearest neighbors. The dormant and active volcanoes can be seen from the International Space Station, as illustrated by the example presented here, that of Kamchatka in Russia, illustrates this very convincingly.

The largest rivers of our planet are crossing the country.
A look at this picture might suggest that it is the Amazon River, but it is actually one of the more than 1,100 tributaries that s & # 39; They throw in it. The Amazon is the only river that carries more water than any other on Earth.

Glaciers and glacial melt reveal a seasonal cyclical planet.
Patagonia glaciers in South America are among the fastest in the world, but their beauty is undeniable. A few minutes ago, ISS was flying over a tropical rainforest, showing how small our planet is.

Windy features common to gas giants appear in our clouds.
These characteristics, which are frequently found in clouds above the oceans, appear whenever there is a limit where the air moves at different speeds relative to each other in different regions. Similar features are commonly observed along atmospheric bands of Saturn and Jupiter.

Lakes seem colorful and depend on the organisms and minerals they contain.
These two lakes, the little cyan on the left and the big blue on the right, are at the top of the Tibetan plateau. The small lake is shallower and is probably populated with algae or some minerals that could give it its unique color.

The collapsed volcanoes reveal hundreds of millions of years of geology.
Known as the Richat structure, it is actually an old collapsed volcano dome, where the oldest parts date back to the Precambrian period, while the youngest ones date back to 400 millions of years. In contrast, sand dunes on both sides change appearance in just a few days.

The atolls display the decaying beauty of erosion and life.
Although it may seem like the Superman logo has encountered a waterfall, you actually see the final stages of an island, formed by volcanism, while it's crumbling. and eroded. This structure is known as the atoll and its outer parts are actually coral reefs that grow along the continental shelf. Finally, it will be all that remains of the Atafu atoll, shown here, and all these structures on Earth.

While our thin atmosphere makes biology possible.
From the ISS, the different layers of our atmosphere, the transient clouds it contains, and the filtered light from our sunshine, are one of the 16 sunrise and sunset that astronauts and astronauts experience every day. .

Our constant monitoring irrefutably demonstrates that human-made changes to the Earth have been made.
The planet Earth, seen in its entirety (as far as can be seen at once) from the GOES-13 satellite, has undergone many changes since we began to continuously monitor our world from space. In all the universe, it is the only house we have.

And a rotating planet, which turns unambiguously.
The MESSENGER satellite, connected to Mercury, captured several amazing images of the Earth during the gravitational assistant of its home planet, August 2, 2005. Several hundreds in sequence in a film describing the view of MESSENGER at the moment he left the Earth. Yes, she is round and yes, she turns on herself and turns around the sun.

Nevertheless, to venture further reveals the cosmic insignificance of the Earth.
The first sight with human eyes of the Earth rising on the branch of the Moon. The discovery of the Earth from space, to the human eye, remains one of the most iconic achievements in the history of our species. Apollo 8, which took place in December 1968, was one of the essential missions to a successful landing on the Moon, which will celebrate its 50th anniversary in July.

From the interplanetary space, our details become blurry and fuzzy.
When the spacecraft Voyager 1 left the Earth, he looked back and took this picture: the first time that a photo of the Earth and Moon was contained in the same frame and showed both in a crescent shaped phase. This image was recorded on September 18, 1977 at a distance of 11.7 million km from the Earth.

At the distance of Mars, the Earth and the Moon are still impressive.
From one of the most successful missions on Mars, Mars Global Surveyor took a little time to look at the Earth, revealing the Earth and the Moon separately, in color and with multiple pixels. This may not seem like a particularly impressive image, but remember that this photo was taken more than 70 million kilometers away.

Seen from Mercury, we are almost always in a complete phase.
The Earth is only an indistinct and featureless sphere, as it emerges from the Messenger space ship, orbiting the planet Mercury. The smallest and closest point of light on Earth is our Moon.
NASA / John's Hopkins University / Washington Carnegie Institute
But as we venture on the outer planets, we are barely a point.
Taken by the Cassini probe with the sun hidden behind Saturn, this backlit view of the great ringed world of our solar system contains a bonus: a few pixels that reveal the Earth-Moon system. It's one of the most distant Earth photographs ever taken, but it still reveals that our world is bigger than a pixel.

From the edge of the solar system, we are barely visible.
This narrow-angle color image of the Earth, nicknamed "Light Blue Point", is part of the very first "portrait" of the solar system made by Voyager 1. The distance that separates Earth from Earth is a simple bright spot, at the size of a picture element even in the narrow-angle camera. The Earth was a crescent of only 0.12 pixels. Coincidentally, the Earth is in the center of one of the scattered light rays resulting from taking the image so close to the sun.
