welcome to planet Earth, the third planet from a star called the Sun. Earth is shaped like a sphere and is made mostly of rock. More than 70 percent of the Earth’s surface is water. The planet has a relatively thin atmosphere made up mostly of nitrogen and oxygen.

The featured image of Earth, named The Blue Marble, o Canica azul, was taken from Apollo 17 in 1972 and shows Africa and Antarctica. It is believed to be one of the most widely distributed photographs of any kind.

Earth has a single large Moon that is about 1/4 its diameter and, from the planet’s surface, is seen to be almost exactly the same angular size as the Sun.

With its abundance of liquid water, Earth is home to a wide variety of life forms, including potentially intelligent species such as dolphins and humans.

According Wikipedia, the name of Blue marble has been applied by NASA, from the year 2012, to a series of image compositions in high resolution that cover the planet, obtained through various satellite photographs, in which it is about removing as much as possible the cloudiness of the image games, with the use of stitching techniques and others, resulting in compositions of digital images, unlike the blue marble, which is a single analog, chemical or conventional photograph.

Please enjoy your stay on planet Earth.
