The first few billion years of Earth's history saw the rise of life, the atmosphere and the oceans. Still, that time is shrouded in mystery: Not many rocks remain that preserve a record of those early iterations of our modern ...
If you've ever taken an introductory astronomy class, you've probably seen the Hertzsprung-Russell (HR) diagram. This graph maps out the life cycle of stars by plotting their temperature against their luminosity, and has ...
Planetary scientists have long debated where the material that formed Earth comes from. Despite its location in the inner solar system, they consider it likely that 6–40% of this material must have come from the outer solar ...
With the current U.S. federal administration abandoning its leadership role in the fight against climate change, international efforts by governments to mitigate global warming appear to have stalled, at least for now. But ...
The asteroid belt is found orbiting between Mars and Jupiter and is a vast collection of rocks that is thought to be a planet that never formed. When our solar system formed 4.6 billion years ago, the material in this region ...
The Northwest can expect a widespread increase in days with cloud-to-ground lightning in the years to come, along with heightened wildfire risk, according to projections made with a unique machine-learning approach developed ...
Headed for a metal-rich asteroid of the same name, the Psyche spacecraft successfully calibrated its cameras by looking homeward.
Elephants are known for their intelligence, strong social bonds, and good memories. But do they communicate to show real intention? A new study suggests they do. The research showed that elephants gestured to ask for food ...
Humans have long mastered the art of expressing their goals and needs through both language and gestures. A similar behavior is also observed in non-human primates, who use complex gestures to convey what they want, but does ...
Analyzing gravity data collected by spacecraft orbiting other worlds reveals groundbreaking insights about planetary structures without having to land on the surface.
