I want to bring you a story that looks to rewrite a bit of our world's history. Researchers studying the geology of an Australian feature called the North Pole Dome, despite being located in Western Australia, found evidence that the feature is associated with a 3.5 billion year old impact. The object that stuck was more than 100 kilometers across and hit at more than 36,000 km/hr. This massive impact turned the local minerals into what are called shatter cones - a kind of fractured rock only found where impacts have occurred. This impact is more than a billion years older than the next...

Our Earth is currently working its way toward being the exact opposite of a snowball Earth as we see glaciers and ice caps receding across the planet. This is fundamentally changing our landscape and how we as humans interact with that landscape.  These changes...

Snowball Earth. Credit: NASA Our planet has been driven to environmental extremes at many times in its history, and many plants and animals - including humans - have demonstrated they can survive less than ideal conditions. The last major ice age hit its peak 20 to 26...

An international team of geoscientists journeyed to northeastern Oregon, where massive volcanism has been linked with climate warming 16 million years ago. For their study, the scientists zeroed in the Wallowa Mountains, which are laced with enormous sheets of flat...

Archaeopteryx Credit: Peter Montgomery Jupiter’s moon Io is the most volcanic object in our solar system today, but our planet gave Io a run for its money more than 200 million years ago. At that point in our planet's history, our world was dominated by the Triassic...
