A powerful earthquake registering 7.7 on the moment magnitude scale has struck central Myanmar early this morning, with tremors also affecting parts of Thailand, including the capital, Bangkok. The United States Geological Survey (USGS) reports that the quake struck near Mandalay at 6:21am GMT, and experts warn that the shallow depth of only 10km (6 miles) could result in extensive damage and a rising death toll in the affected regions.

A groundbreaking discovery by researchers at Curtin University has unveiled the world's oldest known meteorite impact crater, fundamentally altering our understanding of Earth's ancient past. This remarkable find, located in the Pilbara region of Western Australia, reveals that a meteorite impact occurred an astonishing 3.5 billion years ago. The implications of this discovery extend far beyond geology, offering new insights into Earth's formation, the evolution of its crust, and even the origins of life itself.

Over 700 million years ago, Earth underwent one of its most extreme climate events, known as the Sturtian glaciation. During this period, ice sheets covered the entire planet from pole to equator, creating what scientists refer to as a "Snowball Earth." Temperatures plummeted to levels capable of freezing entire oceans, dramatically altering the planet's environment and its potential for life.
