As as we humans discover the universe, we discover ourselves and we understand the importance of our planet, the “Pale Blue Dot” as the only habitable planet known so far! No other planet in the Solar System can offer such stable conditions to life (as we know it)! So let’s stop thinking that we have to save the planet! We need to save our human race as well as the other species that are inhabitants of this planet, let’s face it! Earth will be ok without us… But we NEED this planet! And yes, we have space exploration… BUT… the farthest a human has gone is the Moon, 46 years ago! Mars…. Mmm still a long way to go, important challenges have to be solved like radiation, food and the trip to get there (~6 months in a capsule with dimensions of an elevator!), the nearest exoplanet (planet outside the solar system) in the Alpha Centauri System is 4.36 light years away…. Which means that we would take ~200.000 years to get there (with current technology), that’s the time human has inhabited the planet!!!
Conclusion: start being part of the solution in this #EarthDay let’s contribute to real and sustainable options! Passion and beautiful words won’t save ourselves… What’s your contribution? What are you doing for this and the future generations?? HAPPY EARTH DAY
” I saw for the first time the earth’s shape. I could easily see the shores of continents, islands, great rivers, folds of the terrain, large bodies of water. The horizon is dark blue, smoothly turning to black. . . the feelings which filled me I can express with one word—joy.
Yuri A. Gagarin, first man in space
The “Blue Marble” view of Earth was first captured by astronauts during NASA’s Apollo 8 mission on Dec. 24, 1968. NASA astronauts are given some credit for the origins of Earth Day, as the pictures they take of our planet from space.
Pale Blue Dot
In July 19, 2013 NASA’s Cassini spacecraft captured the color images of Earth and the moon from its perch in the Saturn system nearly 900 million miles (1.5 billion kilometers) away.

It is part of an astronaut’s job in space to capture pictures of our beautiful planet for scientific observation. Here are a few favorite pictures of Earth from space #NoPlaceLikeHome
