IN A NUTSHELL 🌍 Popigai Crater in Siberia, formed by a massive meteorite impact, is the fourth-largest known on Earth. 💎 The impact at Popigai transformed graphite into industrial-quality diamonds due to extreme pressure. 🌌 North American Tektite strewn field possibly formed rings around Earth, influencing climate change. 🦖 The Eocene–Oligocene extinction event saw significant species loss, particularly among aquatic …

A toxic chemical that pollutes groundwater originates high in Earth’s atmosphere, a scientific flight has revealed. Perchlorates, a group of chlorine-containing chemicals that can disrupt thyroid function, form on particles of smoke and organic material in the stratosphere, between 6 and 31 miles (10 to 50 kilometers) above the planet’s surface, according to a new study. Scientists already knew that …

Around 1.1 billion years ago, the oldest and most tectonically stable part of North America — called Laurentia — was rapidly heading south toward the equator. Laurentia eventually slammed into Earth’s other landmasses during the Grenville orogeny to form the supercontinent Rodinia. Laurentia’s path during that period is known, thanks to paleomagnetism. By tracing the orientation and magnetism of rocks …

The Atlantic Ocean did not spring into existence in a sudden tectonic snap; its earliest pulse can now be traced through a set of one-kilometer-long mud waves lying more than 3,000 feet below today’s seafloor some 250 miles west of Guinea-Bissau. New seismic profiles and cores date these colossal ripples to roughly 117 million years old, which shifts the birth …

Recent simulations and research have unveiled a fascinating new insight into the history of the solar system’s terrestrial planets. For years, scientists speculated about how the rocky planets—Earth, Mars, Venus, and the mysterious long-lost world, Theia—formed and evolved in relation to one another. However, a recent study published in The Astrophysical Journal has provided new findings suggesting that these planets, …

A giant blob of abnormally hot rock beneath the Appalachian Mountains formed when Greenland separated from North America around 80 million years ago, new research suggests. Scientists previously thought that this hot zone, known as the Northern Appalachian Anomaly, was left over after North America broke away from Africa 180 million years ago, but this theory does not stand up …

A team of astronomers have discovered a curious figure in the universe. It is two distant galaxies colliding with each other to form a larger structure. From Earth’s perspective, the junction of the disks resembles the number eight lying down, similar to the infinity symbol (∞). Because of this resemblance, the researchers—who are based at the universities of Yale and …
