Study Shows Modern Humans Thrived Through Ancient Toba Supervolcano Eruption
Imagine a year in Africa where summer never arrives. The sky takes on a gray hue during the day and glows red at night. Flowers…

A UNLV scientist has discovered the first direct evidence that fluid water pockets may exist as far as 500 miles (800 kilometers) deep into the…
A new experiment by Elizabeth Swanner evaluating the reduction of iron in prehistoric oceans may reinterpret the conditions under which iron-rich sedimentary rock is formed….
Ancient microbes may have been producing oxygen through photosynthesis a billion years earlier than we thought, which means oxygen was available for living organisms very…
Permafrost in the coldest northern Arctic — formerly thought to be at least temporarily shielded from global warming by its extreme environment — will thaw…
Take a good look at these photos: They show you 1.6 billion years old fossilized oxygen bubbles, created by tiny microbes in what was once…
As ice melts, the organic carbon found in permafrost is released once again after ages of confinement in the soil. It is making its way…
South Africa’s history and economy have been built on its rich natural treasures of a number of precious metals, stones, and minerals. The country’s mineral…
It’s amazing what a difference a little water can make. The Moon formed between about 4.4 and 4.5 billion years ago when an object collided…
A novel research study by scientists at the University of Liverpool has provided new insights into how molten rock (magma) moves through the Earth’s crust…
A NASA study based on an innovative technique for crunching torrents of satellite data provides the clearest picture yet of changes in Antarctic ice flow…
Sometimes on a dark night near the poles, the sky pulses a diffuse glow of green, purple and red. Unlike the long, shimmering veils of…
For the first four billion years of Earth’s history, our planet’s continents would have been devoid of all life except microbes. All of this changed…
The shower of electrons bouncing across Earth’s magnetosphere – commonly known as the Northern Lights – has been directly observed for the first time by…
In popular culture, asteroids play the role of apocalyptic threat, get blamed for wiping out the dinosaurs — and offer an extraterrestrial source for mineral…
The year 2017 was a record-breaking one for Operation IceBridge, NASA’s aerial survey of the state of polar ice. For the first time in the…
Twenty-five years of satellite data prove climate models are correct in predicting that sea levels will rise at an increasing rate. In a study published…
Geophysicists have obtained detailed three-dimensional images of a dangerous megathrust fault west of Costa Rica where two plates of the Earth’s crust collide. The images…
