It shows our home planet from deep space. This image helps us see how small and alone Earth is. It also shows how fragile our world can be. Many people use this image to think about the environment. It has become a powerful symbol for protecting nature.

To make this photo, an astronaut used a special camera.

The camera was a 70-millimeter Hasselblad with a Zeiss lens. The astronaut was on a path toward the Moon. They looked back and saw the Earth below them. To the crew, the planet looked like a small glass marble. The sun was above the spacecraft at that time. This lighting helped show the bright colors of the Earth.

Harrison Schmitt was the astronaut on the Apollo 17 mission. Apollo 17 was the very last crewed mission to the Moon. The photo was taken at 5:39 a.m. EST. It happened about two hours after the ship left Earth's orbit. While the crew members Gene Cernan and Ronald Evans also took photos, evidence suggests Schmitt took this one. It is a very special piece of history from the Apollo era.

The photo shows many amazing details of our world. You can see the coast of Africa and Madagascar. The Indian Ocean is also very clear in the view. You can even see a cyclone near the center of the image. This storm was called the Shapyro–Keyser cyclone. The image also shows the South Pole for the first time. This was possible because of the specific path the spacecraft took. Many different lands like Australia and South America are on the edges.

Since we cannot take one perfect photo of the whole Earth at once, we use composites. A composite is a picture made by joining many smaller photos together. NASA used this method in 2012 to make very clear images. They looked through many satellite pictures to find parts without clouds. They also made "Black Marble" images to show city lights at night. These tools help us study how humans use the planet every day.
