A 1976 NASA satellite carries a Sagan-designed plaque that timestamps Earth through deep time

NASA’s LAGEOS-1, launched in 1976, is a bare-bones, durable satellite designed to reflect laser pulses for geodynamics research. It carries two Carl Sagan–designed stainless-steel plaques with three maps showing Earth’s continents 268 million years ago (Pangaea), at launch in 1976, and about 8.4 million years in the future—the latter date aligned with the satellite’s expected re-entry. The plaque is not targeted at aliens but serves as a timekeeping message, dating itself via continental drift while the satellite—an electronics-free sphere studded with reflectors—awaits eventual opening when it returns to Earth.

Ancient Molten Blob Threatens New York After Tearing Continents Apart

Scientists have identified the Northern Appalachian Anomaly, a massive molten rock formation beneath New England, which originated from the Labrador Sea 80 million years ago and continues to drift slowly, influencing Earth's geological structure and supporting theories of mantle wave activity that shape continental features over millions of years.

Massive Hot Blob Approaching NYC with Continental-Dividing Power

A study suggests a massive hot rock formation called the Northern Appalachian Anomaly is moving towards New York City from deep beneath the Earth's crust, potentially explaining aspects of Earth's geological history and continental movement, but it won't reach NYC for another 15 trillion years.

Fast-Moving Continent Approaching Asia, Risks of Catastrophic Impact

Australia is drifting northward towards Asia at about 7 centimeters per year, a slow process driven by plate tectonics that will eventually lead to a collision, causing significant geological and ecological changes, including mountain formation, increased seismic activity, and threats to Australia's unique wildlife.

Ancient Dinosaur Footprints Across the Atlantic Confirm Connection

Fossilized dinosaur footprints found in Cameroon and Brazil, dating to about 120 million years ago, reveal a once-connected land corridor across the Atlantic, providing new insights into dinosaur migration and the breakup of Gondwana.

Earth's Sixth Ocean Emerges: A Geological Marvel in Progress

Scientists have observed the formation of Earth's sixth ocean as tectonic plates slowly drift apart, reshaping the African continent. The Arabian and Somali plates are moving away from the African plate, creating a rift in the East African Rift Valley, which could eventually flood and form a new ocean. This geological shift may alter the geography and economic prospects of several countries, potentially giving landlocked nations like Zambia and Uganda coastal access. Advanced GPS technology allows precise tracking of these tectonic movements, offering insights into Earth's geological future.

"Lost Continent of Argoland Rediscovered in Asia After 155 Million Years"

Scientists from Utrecht University have rediscovered the ancient continent of Argoland, which broke off from Australia 155 million years ago. The landmass was found hidden under the eastern islands of Southeast Asia, explaining the invisible barrier known as the Wallace line that separates Southeast Asian and Australian fauna. Argoland shattered into fragmented ribbons, obstructing its discovery until now. This discovery could provide insights into the evolution of biodiversity, climate, and the distribution of wildlife in the region.

"Scientists Uncover Ancient 'Lost Continent' After 155 Million Years"

Geologists from Utrecht University have discovered a lost continent named "Argoland" that broke off from Australia and sank to the bottom of the Indian Ocean 155 million years ago. The 3,000-mile-wide landmass was found after years of searching and provides valuable insights into the Earth's geological past and processes such as plate tectonics. The discovery of Argoland helps fill in missing pieces of history and prevents a larger scientific problem of disappearing into the mantle.
