Earth-Like Worlds Could Have Formed Billions of Years Earlier Than Scientists Thought
1+ hour, 17+ min ago (1092+ words) Rocky planets may have gotten their start far earlier than anyone expected, almost as soon as the first stars gave the universe the ingredients to build them. New computer simulations suggest that planetesimals, the solid precursors of planets like Earth,…...
Scientists Discover a 3.7-Billion-Year-Old Secret of Early Life
9+ hour, 35+ min ago (487+ words) Ancient microbes appear to have used molybdenum as far back as 3.7 billion years ago, despite the metal being scarce in Earth’s early oceans. Scientists funded by NASA have found that organisms living on Earth more than 3 billion years ago were…...
A 2-Billion-Year-Old Clue Challenges a Popular Earth Science Theory
3+ day, 39+ min ago (464+ words) A key geological clue to a global disruption in Earth’s ancient carbon cycle may have a more local origin. Between roughly 2.5 and 2 billion years ago, Earth underwent the greatest chemical transformation known from its surface history as oxygen accumulated in…...
Scientists Identify a Surprising 129-Day Limit for Predicting the Weather
3+ day, 1+ hour ago (352+ words) A new study suggests the atmosphere may retain enough information for weather to remain theoretically predictable for roughly 129 days under ideal conditions. How far into the future could weather ever be predicted, even if forecasters knew the atmosphere perfectly? Meteorologists…...
Scientists Survey Mount Ararat???s Mysterious Glacier for the First Time
6+ day, 8+ hour ago (387+ words) A German and Turkish research team is studying a shrinking glacier as a record of past climate and environmental change. More than 5,000 meters above sea level, amid intense cold, strong winds, and oxygen levels roughly half those in the valley…...
A Key Atlantic Ocean Current Did the Opposite of What Scientists Expected
1+ week, 2+ day ago (1098+ words) Scientists thought they knew what helped keep the Atlantic’s vast circulation system running, but evidence from millions of years ago has revealed a surprising exception. Sediments deposited on the seafloor millions of years ago reveal an unexpected episode in Earth’s…...
This Fossil Upends a Decades-Old Debate About Snake Evolution
1+ week, 4+ day ago (301+ words) More than 4,000 snake species live today, yet the evolutionary path that produced their elongated, limbless bodies remains difficult to reconstruct. Snakes are highly modified lizards, but their limited fossil record has left one of evolutionary biology’s central questions unresolved. Scientists…...
Dark Matter May Be Leaving a Signal in Earth???s Atmosphere
1+ week, 6+ day ago (451+ words) Earth itself may be one of the world’s largest detectors for ultralight dark matter. Earth may already contain one of the largest dark matter experiments ever built. Instead of relying only on specialized equipment inside a laboratory, scientists have found…...
Scientists Discover a 300-Million-Year-Old Geological Time Capsule Inside Fossilized Wood
1+ week, 6+ day ago (723+ words) Researchers used quartz from fossilized wood to trace how Europe developed. A polished piece of fossilized wood may look like little more than a decorative stone, yet the quartz inside it can preserve the history of an entire region for…...
Meteorite That Smashed Through a New Jersey Roof Hid an Ancient Chemical Secret
2+ week, 3+ day ago (1112+ words) A meteorite that blasted through a New Jersey roof carried a startling secret: evidence of ancient salty fluids and complex organic chemistry inside a primitive asteroid. A space rock that tore through a New Jersey roof has turned out to…...
