Stretching more than 200,000 square kilometers (77,000 square miles) across southern Australia, the vast, flat plains of the Nullarbor mark one of the world's largest regions of limestone. It formed when an ancient shallow ...
Ice sheets are fundamental components of the Earth system. Antarctica and Greenland, the two ice sheets currently on Earth, don't just affect their own regions: What happens on these vast masses of land ice influences weather, ...
Many of the moons orbiting Saturn, Uranus and Neptune likely conceal oceans of liquid water beneath miles of icy shell. Because life as we know it needs water, these buried oceans rank among the most promising places to search ...
Magnetic reconnection is a process that occurs when the magnetic fields of a conductive plasma quickly rearrange and release massive amounts of stored magnetic energy. It is widely thought to be the underlying mechanism behind ...
When the solar system first took up the task of building solid bodies—such as planets, moons and protoplanets—it basically had a choice between two ingredients: heat-forged chondrules, which were millimeter-sized bits of ...
A team of researchers, including those from the University of Tokyo, spotted a rare kind of planet that's unusually hot and eccentric. TOI-1355 b orbits its star, TOI-1355, which is also much hotter than our sun, in a strange ...
Nitrogen is a key nutrient because it fuels the growth of plankton, which forms the basis of the marine food web. Two opposing processes determine the global nitrogen cycle: nitrogen fixation and denitrification.
Researchers at the National High Magnetic Field Laboratory and Brookhaven National Laboratory have teamed up to get a fresh look at the complex makeup of meteorites and glimpse into our solar system's past.
Every new generation of phone display, television screen and solar panel is the result of precision optics experiments, which use lasers and other light sources to measure the optical properties of candidate materials. These ...
Forests and woodlands cover millions of hectares across Australia, from tropical rainforests and temperate eucalypt forests to the vast woodlands and shrublands of the arid interior. They store enormous amounts of carbon, ...
