Earth formed about 4.54 billion years ago by accretion from the solar nebula, a disk-shaped mass of dust and gas left over from the formation of the Sun, which also created the rest of the Solar System. Initially, Earth was molten due to extreme volcanism and frequent collisions with other bodies.
The geological time scale (GTS), as defined by international convention, [3] depicts the large spans of time from the beginning of Earth to the present, and its divisions chronicle some definitive events of Earth history. Earth formed around 4.54 billion years ago, approximately one-third the age of the universe, by accretion from the solar nebula.
The timeline of first Earth observation satellites shows, in chronological order, those successful Earth observation satellites, that is, Earth satellites with a program of Earth science. Sputnik 1, while the first satellite ever launched, did not conduct Earth science.
The earliest maps ignored the curvature of Earth's surface, both because the shape of the Earth was uncertain and because the curvature is not important across the small areas being mapped. However, since the age of Classical Greece , maps of large regions, and especially of the world, have used projection from a model globe to control how the ...
Here are some fun map facts for you: one of the oldest surviving maps is the Babylonian Map of The World. Archaeologists date it back to around 700 to 500 B.C. The map was a clay tablet nearly the ...
The Blue Marble is a photograph of Earth taken on December 7, 1972, by either Ron Evans or Harrison Schmitt aboard the Apollo 17 spacecraft on its way to the Moon.Viewed from around 29,400 km (18,300 mi) from Earth's surface, [1] a cropped and rotated version has become one of the most reproduced images in history.
NASA Earth science satellite fleet as of September 2020, planned through 2023. Earth observation satellite missions developed by the ESA as of 2019. Earth observation satellites are Earth-orbiting spacecraft with sensors used to collect imagery and measurements of the surface of the earth. These satellites are used to monitor short-term weather ...
