Earth
Earth is the third planet from the Sun and the only object in the Universe known to harbor life. According to radiometric dating and other sources of evidence, Earth formed over 4.5 billion years ago. Earth's gravity interacts with other objects in space, especially the Sun and the Moon, Earth's only natural satellite. Earth revolves around the Sun in 365.26 days, a period known as an Earth year. During this time, Earth rotates about its axis about 366.26 times.
Earth Observation
Earth observation (EO) is the gathering of information about the planet's physical, chemical, and biological systems via remote-sensing technologies, supplemented by earth-surveying techniques, which encompasses the collection, analysis, and presentation of data. Earth observation is used to monitor and assess the status of and changes in natural and built environments.
Observation
Observation is the active acquisition of information from a primary source. In living beings, observation employs the senses. In science, observation can also involve the recording of data via the use of scientific instruments. The term may also refer to any data collected during the scientific activity. Observations can be qualitative, that is, only the absence or presence of a property is noted, or quantitative if a numerical value is attached to the observed phenomenon by counting or measuring.
Earth
This poor world, the object of so much insane attachment, we are about to leave; it is but misery, vanity, and folly; a phantom, — the very fashion of which "passeth away."
François Fénelon, reported in Josiah Hotchkiss Gilbert, Dictionary of Burning Words of Brilliant Writers (1895), p. 206.
Earth
Earth below us
drifting, falling.
Floating weightless
calling, calling home...
Peter Schilling, song Major Tom (Coming Home) (1983).
Observation
Scientists believe that nature is orderly and measurable— that natural laws, such as the law of gravity, do not change with time, and that a natural event, or phenomenon,can be understood more fully through observation. Scientists use all of their senses in making observations.
