Data from an enormous earthquake in Bolivia showed mountains at the base of the mantle's transition zone, located 660 kilometers below our feet. These mountains may be bigger than anything on the surface of the Earth.
A spacecraft has successfully fired a harpoon into a target orbiting Earth in an operation that could help clean-up the tonnes of space junk threatening telecommunications satellites.
Scientists have found that the magnetic north pole is moving at a speed of about 55 km every year. A hundred years ago, the pole was located near the coast of northern Canada. Now, it is in the middle of the Arctic Ocean.
From planting continent-long forests to inducing rainfall, researchers have begun proposing, testing, and in some cases implementing large-scale geoengineering projects to radically transform the planet.
An international team of scientists found evidence that the rock was launched from Earth by a large impacting asteroid or comet. The impact sent material into space, where it collided with the surface of the Moon 4 bil years ago.
Researchers plan to spray sunlight-reflecting particles into the stratosphere, an approach that could ultimately be used to quickly lower the planet’s temperature.
This phenomenon has affected a large part of the globe, which originated – according to the hypotheses – about 24 km off the coast of Mayotte, a French island located between Africa and the northern tip of Madagascar.
Microbes could have performed oxygen-producing photosynthesis at least one billion years earlier in the history of the Earth than previously thought.
Collisions of underwater tectonic plates are pulling about three times as much water deep into the Earth than what was previously calculated.
An international team has discovered a 31-km wide meteorite impact crater buried beneath the ice-sheet in the northern Greenland. This is the first time that a crater of any size has been found under one of Earth.
Antarctica was once part of the supercontinent Gondwana, which began to disintegrate some 130 million years ago, although the bond between Antarctica and Australia held together as recently as 55 million years ago.
The first comprehensive fine-scale map of the world's remaining marine and terrestrial wild places shows that just 23 percent of the world's landmass can now be considered wilderness, with the rest lost.
Populations of mammals, birds, fish, reptiles, and amphibians have, on average, declined in size by 60 percent in just over 40 years.
Since 1991, the world's oceans have absorbed an amount of heat energy each year that is 150 times the energy humans produce as electricity annually, according to a new study.
Recent studies have shown that global emissions of carbon tetrachloride, that contributes to the destruction of the Earth's ozone layer, have not declined as expected, with about 40,000 tonnes still being emitted each year.
