A team of researchers from the University of Göttingen and the Max Planck Institute for Solar System Research (MPS) has made a significant discovery about the origins of the Moon and the presence of water on Earth. Previously, scientists believed the Moon formed after a massive collision betwe...

Although it is not known when or where life on Earth began, some of the earliest habitable environments may have been submarine-hydrothermal vents. Here we describe putative fossilized microorganisms that are at least 3,770 million and possibly 4,280 million years old in ferruginous sedimentary roc...
When did life first arise on Earth? Analysis of ancient rocks in Greenland that contain structures interpreted as bacterial in origin suggest that Earth might have been an abode for life much earlier than previously thought. See Letter p.535 Stromatolite
A 40-mile stretch of a long-gone branch of the Nile may explain why the ancient monuments were built where they were.
What's next for exploration of Earth's only natural satellite. Researchers reexamining data collected from decades of exploration of the Moon’s surface now believe a complex system of caves exists that could impact future missions. NASA said the lunar caves likely formed when molten lava once fl...
” The first direct evidence of beeswax opens up fascinating perspectives for the archaeology of Africa. Neumann: “We assume that the use of honey in Africa has a very long tradition. The oldest pottery on the continent is about 11,000 years old. Does it perhaps also contain be...
(海王星)average distance to the sun is about 4.5 billion kilometers.But "Planet Nine" could be 20 times farther away from the sun than that.$\qquad$While they did not get a picture of "Planet Nine" yet,the scientists say they are using the biggest—and the best—telescopes on earth ...

Fomation of a glacier is complete when ice has accumulated to a thickness (and thus weight) sufficient to make it move slowly under pressure, in much the same way that solid rock deep within the Earth can change shape without breaking. Once that point is reached, the ice flows downhill,...
