Near Earth Objects (NEOs) are small solar system bodies whose orbits sometimes bring them close to the Earth, potentially threatening a collision. NEOs are tracers of the composition, dynamics, and environmental conditions throughout the solar system, and of the history of our planetary system. Most meteorites come from Near Earth Objects, which are thus one ...
Crescent dunes and meandering rivers can “forget” their initial shapes as they are carved and reshaped by wind and water, while other landforms keep a memory of their past shape, suggests new research. Leif Ristroph from New York University and the senior author of the paper, which is published in the journal Physical Review Fluids, said: “Asking ...
A study of the most recent near-reversals of the Earth’s magnetic field by an international team of researchers, including the University of Liverpool, has found it is unlikely that such an event will take place anytime soon. There has been speculation that the Earth’s geomagnetic fields may be about to reverse, with substantial implications, due ...
Scientists conclude methane-producing microbes date back 3.5 billion years, supporting the hypothesis that they could have contributed to early global warming. Early forms of life very likely had metabolisms that transformed the primordial Earth, such as initiating the carbon cycle and producing most of the planet’s oxygen through photosynthesis. About 3.5 billion years ago, the ...
Lawrence Livermore National Laboratory (LLNL) scientists are part of a national planetary defense team that designed a conceptual spacecraft to deflect asteroids that are Earth-bound, and evaluated whether it would be able to nudge a massive asteroid — which has a remote chance of hitting Earth in 2135 — off course. The design and case ...
Does China have creation stories? The answer is yes, and the name of the first creation God is Pangu. At the beginning of time, the universe was unformed, and Heaven and Earth were unseparated. It was like a round egg, in which there was no light or sound. In the universal egg lay a sleeping ...
