No matter where you live on Earth, you experience seasons, as we pass from Spring to Summer to Fall to Winter, and then back to Spring again.
Why do we have variations in temperature at all? What causes the seasons?
Mystery of Earth’s spinning core solved. Scientists at the University of Leeds have solved a 300-year-old puzzle. Earth’s inner core spins in eastward direction, the opposite to the outer core.
Using previously published large-scale climate model projections, a team of scientists from NASA, the Climate Analytics Group, Palo Alto, Calif., a non-profit that provides climate data services, and California State University, Monterey Bay, has released monthly climate projections for the coterminous United States at a scale of one half mile (800 meters), or approximately the size of a neighborhood. To generate these high-resolution climate projections, researchers used an innovative scientific collaboration platform called the NASA Earth Exchange (NEX), at NASA’s Ames Research Center in Moffett Field, Calif.
In the deepest, darkest parts of the oceans are ecosystems with more diversity than a tropical rainforest. Taking us on a voyage into the ocean — from the deepest trenches to the remains of the Titanic — marine biologist David Gallo explores the wonder and beauty of marine life.
Sometimes, Earth mimics a supernova, producing a Terrestrial Gamma-ray Flash from the tops of thunderstorms. A new lightning sensor on the International Space Station could solve the mystery of these energetic bursts.
Signs of life on the Martian surface would still be visible even after bacteria were zapped with a potentially fatal dose of radiation, according to new research — if life ever existed there, of course.
Scientists from the British Antarctic Survey have found life in mud samples at the bottom of a sub-glacial lake in Antarctica. They found microbes dating back almost 100,000 years as well as organisms previously unknown to science. The research team from the British Antarctic Survey and the universities of Northumbria and Edinburgh made their astonishing […]
A nuclear accident devastated the region near Chernobyl, Ukraine, on April 26, 1986 leaving behind a 2,600 km² exclusion zone where some 350,000 people were evacuated. This vast area, where time has stood still ever since, is springing back to life with wildlife. The evacuation of the human population has created a unique wildlife refuge which has seen an increase in biodiversity.
Deep space may be the final frontier, but we already know more about the orbits of stars around the supermassive black hole at the center of Milky Way, than we do about the behavior of the colossal squid and other creatures that live deep in the oceans here at home.
The Earth is 4.6 billion years old — but how can humans relate to a number so colossal, and where do we fit on the geologic timeline? Comparing the Earth’s lifetime to one calendar year, events like the extinction of dinosaurs and Columbus setting sail took place relatively recently. Joshua M. Sneideman reminds us of our time and place in the universe.
A series of mysterious ancient pipe-like features named Baigong Pipes, found on and near Mount Baigong, about 40 km southwest of the city of Delingha, in the Haixi Mongol and Tibetan Autonomous Prefecture, Qinghai Province, China. The most recent researchers to examine the pipes believe that the metallic phenomenon are in fact …
Scientists from the Integrated Ocean Drilling Program have discovered bacteria, viruses and fungi living over 1.5 miles under the ocean floor in thick sedimentary rock, which dates back over 100m years. The lifeforms are only just surviving though, reproducing once every 10,000 years or so. Nevertheless the discovery raises questions over where life on Earth can survive.
