A giant collision between the ancient protoplanet Theia and the proto-Earth about 4.5 billion years ago may have formed Earth’s Moon as well as two continent-sized...
About 66 million years ago, a massive asteroid crashed into Earth near the site of the small town of Chicxulub in what is now Mexico. The impact eradicated...
Geoscientists from Durham University and elsewhere have discovered a landscape that appears to have been formed by rivers at least 14 million years ago...
By analyzing tiny lunar zircon crystals gathered by Apollo 17 astronauts in 1972, planetary scientists recalculated the age of the Moon. Although previous...
Around 12,800 years ago, Earth collided with fragments of a disintegrating comet, triggering Younger Dryas climate change; this event created environmental...
Earth’s magnetic field is occasionally but regularly impacted by bursts of energy from the Sun (space weather), such as coronal mass ejections. Birds...
In new research, scientists from the University of Leeds and elsewhere measured radiocarbon levels in ancient trees preserved within the eroded banks of...
Revealed by 3D seismic imaging, the newly-discovered water reservoir lies 3.2 km (2 miles) under the ocean floor off the coast of New Zealand, where it...
Physicists from the ALPHA Collaboration at CERN’s Antimatter Factory have demonstrated the existence of gravity between antimatter and Earth, reaffirming...
While it is known that for diamonds to form there needs to be carbon deep in the Earth, and for these diamonds to turn pink they must be subjected to forces...
Planetary scientists from the University of Hawaii and elsewhere suggest that although they have confirmed the importance of the solar wind as a major...
On September 14, 2023, the NASA Unidentified Anomalous Phenomena independent study team published its final report containing a series of recommendations...
The global extent of supplementary bird feeding is unknown but has consequences for bird conservation and human well-being. Using a measure of search intensity...
New research from the University of Toronto shows that from approximately 2 billion until 600 million years ago, an atmospheric tide driven by the Sun...
The evolution of life on Earth has changed dramatically at tens of million-year time scales. However, the causal mechanisms of these changes remain unclear....
Harvard University’s Professor Avi Loeb and colleagues have discovered at least 50 tiny spherical iron fragments near the fireball path of the first...
The 50-km-diameter granitic system discovered below the far side feature known as Compton-Belkovich Volcanic Complex likely was formed from the cooling...
