Did some of Earth"s water come from the solar wind?
The source of Earth's water is an enduring mystery that extends to exoplanets and the notion of habitability. In broad terms, Earth's water was either part of the planet from the beginning of its formation in the solar nebula or delivered later, mayb.....»»
Why Hurricane Milton Turned the Sky Purple
The strange, apocalyptic skies during the storm reveal how light behaves in the atmosphere when it’s filled with an unusual amount of water vapor, dust, and debris......»»
On US coast, wind power foes embrace "Save the Whales" argument
Whether from real concern for marine animals or doubts about renewable energy, the anti-wind power movement has been growing along the US East Coast, with some trying to blame a surge in whale strandings on the growth of offshore energy projects......»»
Apple’s new Submerged movie for Vision Pro is not for bathtime viewing
Apple's new Submerged movie for the Vision Pro features a lot of panic and a lot of water, so don't even think about watching it in the bath. .....»»
New analysis tools can help farmers make informed choice on "agrivoltaics"
The dual use of land for agriculture and solar energy production, known as agrivoltaics, presents a new opportunity for farmers, but whether it makes economic sense for growers is a complex question. A new set of analytical tools developed by researc.....»»
Asteroid mining: A potential trillion-dollar industry
Earth's newest celestial neighbor has finally arrived. Astronomers using a powerful telescope in Sutherland, South Africa, first detected the 33-foot-long asteroid in August, reporting their discovery in Research Notes of the American Astronomical So.....»»
These five "post-truth" claims are fueling the water wars in Australia
The contest between truth and post-truth matters when trying to solve big public policy questions. One of these questions is how to sustainably manage water in Australia for the benefit of all......»»
Measures to restore biodiversity in peatlands fall short, study finds
Research by ecologist Tom Heuts of Radboud University shows that several experimental measures taken at Frisian farms to restore biodiversity in former peatlands were unsuccessful. Three methods in which the water levels were raised did not have the.....»»
How did magma oceans evolve on early Earth and Mars? Iron chemistry and primordial atmospheres offer clues
Before Earth became the blue planet, it was engulfed by a very different kind of ocean: a vast, deep magma ocean reaching down hundreds or perhaps even thousands of kilometers......»»
Catastrophically warm predictions are more plausible than previously thought, say climate scientists
What will the future climate be like? Scientists around the world are studying climate change, putting together models of the Earth's system and large observational datasets in the hopes of understanding—and predicting over the next 100 years—the.....»»
Scientists recreate sound of Earth"s magnetic flip 41,000 years ago
Approximately 41,000 years ago, Earth's magnetic field briefly reversed during what is known as the Laschamp event. During this time, Earth's magnetic field weakened significantly—dropping to a minimum of 5% of its current strength—which allowed.....»»
Scientists track and analyze lofted embers that cause spot fires
In the chaos of a wildfire, heat, wind, flames and fuel interact to produce embers that are lofted into surrounding areas, starting new spot fires and spreading destruction and property loss in California's wildland-urban interface......»»
Northern lights may be visible in much of upper US on Thursday, Friday
Still haven't caught a glimpse of those shimmery northern lights? Minnesotans have a good chance to snag one of those popular aurora borealis photos at the end of this week thanks to a "severe" geomagnetic storm expected to reach Earth on Thursday......»»
Hurricane Milton Shows How a Storm’s Category Doesn’t Tell the Full Story
Milton’s reclassification to a Category 3 storm suggests it is weakening, but the scale accounts only for wind speed and not hurricane size, storm surge heights, or rainfall—which are all catastrophically large......»»
US forecasts severe solar storm starting Thursday
A massive ball of plasma and accompanying magnetic field ejected from the sun is expected to strike Earth on Thursday morning, potentially triggering auroras as far south as Alabama, according to US forecasters......»»
Cosmic-ray neutron rover assists in estimating mesoscale soil moisture on eastern Qinghai-Tibetan plateau
Soil water resources are crucial for hydrological processes and ecosystem functions on the Qinghai-Tibetan Plateau. However, accurately measuring soil moisture distribution in this region is challenging due to diverse ecosystems, complex terrain, and.....»»
How to watch Crew-8 depart the space station on Sunday
Three American astronauts and a Russian cosmonaut are preparing to depart the International Space Station about 250 miles above Earth......»»
Jupiter"s Great Red Spot shows unexpected size changes
Astronomers have observed Jupiter's legendary Great Red Spot (GRS), an anticyclone large enough to swallow Earth, for at least 150 years. But there are always new surprises—especially when NASA's Hubble Space Telescope takes a close-up look at it......»»
NASA terminal transmits first laser communications uplink to space
NASA's LCOT (Low-Cost Optical Terminal), a ground station made of modified commercial hardware, has transmitted its first laser communications uplink to the TBIRD (TeraByte Infrared Delivery), a tissue box-sized payload formerly in low Earth orbit......»»
Severe solar storm could stress power grids even more as US deals with major back-to-back hurricanes
A severe solar storm is headed to Earth that could stress power grids even more as the U.S. deals with major back-to-back hurricanes, space weather forecasters said Wednesday......»»
Astronomers race to capture image of exoplanet near star
Planet AF Lep b is a world of firsts. In 2023, it was the lowest-mass planet outside our solar system to be directly observed and have its mass measured using astrometry. This is a technique that charts the subtle movements of a host star over many y.....»»
