The history of Earth concerns the development of planet Earth from its formation to the present day. [ 1 ] [ 2 ] Nearly all branches of natural science have contributed to understanding of the main events of Earth's past, characterized by constant geological change and biological evolution .
Artemis 1, officially Artemis I [10] and formerly Exploration Mission-1 ( EM-1 ), [11] was an uncrewed Moon-orbiting mission. As the first major spaceflight of NASA 's Artemis program, Artemis 1 marked the agency's return to lunar exploration after the conclusion of the Apollo program five decades earlier. It was the first integrated flight ...
The geologic time scale is a way of representing deep time based on events that have occurred throughout Earth's history, a time span of about 4.54 ± 0.05 Ga (4.54 billion years). [5] It chronologically organises strata, and subsequently time, by observing fundamental changes in stratigraphy that correspond to major geological or ...
Voyager 1 is a space probe launched by NASA on September 5, 1977, as part of the Voyager program to study the outer Solar System and the interstellar space beyond the Sun's heliosphere. It was launched 16 days after its twin, Voyager 2.
The geological history of the Earth follows the major geological events in Earth's past based on the geological time scale, a system of chronological measurement based on the study of the planet's rock layers ( stratigraphy ). Earth formed about 4.54 billion years ago by accretion from the solar nebula, a disk-shaped mass of dust and gas left ...
e. The Pleistocene ( / ˈplaɪstəˌsiːn, - stoʊ -/ PLY-stə-seen, -stoh-; [ 5][ 6] often referred to colloquially as the Ice Age) is the geological epoch that lasted from c. 2.58 million to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations.
[1] 10:28:25: The North Tower of the World Trade Center collapses, 1 hour and 42 minutes after the impact of Flight 11. The Marriott Hotel, located at the base of the two towers, is also destroyed. [1] [3] 10:50:19: All five stories of the Pentagon on the West side where American 77 crashed collapsed due to the fire started by the crash.
Timeline of space exploration. This is a timeline of space exploration which includes notable achievements, first accomplishments and milestones in humanity's exploration of outer space . This timeline generally does not distinguish achievements by a specific country or private company, as it considers humanity as a whole.
