Using the Earth"s noise to see beneath the Greenland ice sheet
The noise created by the Earth's movements has been used to build up a detailed picture of the geological conditions beneath the Greenland Ice Sheet and the impact on ice flow, described in new research led by Swansea University. .....»»
NASA is working on a plan to replace its space station, but time is running out
"Initially, Congress almost treated the program as a joke." The next year is crucial for the future of NASA and its plans to extend human activity in low-Earth orbit. For the firs.....»»
NASA"s laser comms demo makes deep space record, completes first phase
The Deep Space Optical Communications tech demo has completed several key milestones, culminating in sending a signal to Mars' farthest distance from Earth......»»
Scientists offer a detailed look at the skeleton of an ancient predator that thrived in extreme conditions
Imagine a world on the brink of collapse: volcanic eruptions spewing toxic gases, oceans turning acidic, and up to 90% of Earth's species vanishing in the blink of an eye. This was the reality at the end of the Permian Period, around 252 million year.....»»
2-billion-year-old rock could help understand very early life on Earth and the hunt for evidence of life on Mars
Pockets of microbes have been found living within a sealed fracture in a 2-billion-year-old rock. The rock was excavated from the Bushveld Igneous Complex in South Africa, an area known for its rich ore deposits. This is the oldest example of living.....»»
Lunar mission data analysis finds widespread evidence of ice deposits
Deposits of ice in lunar dust and rock (regolith) are more extensive than previously thought, according to a new analysis of data from NASA's LRO (Lunar Reconnaissance Orbiter) mission. Ice would be a valuable resource for future lunar expeditions. W.....»»
Ancient protein structure may have enabled early molecular evolution and diversification
In a finding that offers fresh insights into the early evolution of life on Earth, two RIKEN biologists have conducted lab experiments that have revealed a previously unknown protein fold, which is completely absent in modern proteins......»»
Mathematicians and climate researchers build new models for understanding polar sea ice
Polar sea ice is ever-changing. It shrinks, expands, moves, breaks apart, reforms in response to changing seasons, and rapid climate change. It is far from a homogenous layer of frozen water on the ocean's surface, but rather a dynamic mix of water a.....»»
Researchers develop Biodiversity Digital Twins to model our planet"s life
Biodiversity is essential for the processes that support all life on Earth. It provides critical resources such as food and energy, and supports ecosystem health. However, climate change, deforestation, and pollution are destroying habitats, altering.....»»
Iron nuggets in the Pinnacles unlock secrets of ancient and future climates
Small iron-rich formations found within Western Australia's Pinnacles, which are part of the world's largest wind-blown limestone belt spanning more than 1,000km, have provided new insights into Earth's ancient climate and changing landscape......»»
Surprising amount and variety of gamma radiation is produced in large tropical thunderstorms, observations reveal
In the 1990s, NASA satellites built to spot high-energy particles coming from supernovas and other celestial-sized objects discovered a surprise—high energy gamma radiation bursts coming from right here on Earth......»»
Q&A: Using a new approach to shine a light on hidden plant microbes
Despite there being more microbes on Earth than stars in our galaxy, only a tiny fraction have been discovered. An approach called metagenomics—a type of DNA sequencing—may help scientists learn more about these elusive organisms, according to Pe.....»»
Swiss glaciers are receding again after 2 punishing years and despite a good start to 2024
The volume of Switzerland's glaciers shrank again this summer, compounding the negative impact of climate change after a devastating two-year run that depleted the ice by more than 10%, scientific experts reported Tuesday......»»
Are plants and fungi trading carbon for nutrients? Not likely, say researchers
Every year, plants move 3.58 gigatons of carbon to mycorrhizal fungi, their underground partners—enough, in fact, that if it were ice, it would cover 112 million NHL hockey rinks. However, a dominant scientific theory explaining that huge transfer.....»»
Scientists find plausible geological setting that may have sparked life on Earth
Researchers have discovered a plausible evolutionary setting in which nucleic acids—the fundamental genetic building blocks of life—could enable their own replication, possibly leading to life on Earth......»»
Opinion: Enough, already—why humanity must get on board with the concept of "sufficiency"
Humanity's rapacious consumption is more than Earth and its climate can handle, which is driving an ecological crisis. Australians are the worst offenders per person due to our excessive resource use......»»
Most climate scientists foresee temperature rise exceeding Paris Agreement targets, study finds
A new survey of climate experts reveals that a majority believe the Earth to be headed for a rise in global temperatures far higher than the 2015 Paris Agreement targets of 1.5 to well-below 2°C......»»
NASA"s instruments capture sharpest image of Earth"s radiation belts
From Aug. 19–20, ESA's (European Space Agency's) Juice (Jupiter Icy Moons Explorer) mission made history with a daring lunar-Earth flyby and double gravity assist maneuver, a spaceflight first. As the spacecraft zipped past our moon and home planet.....»»
Scientists highlight overlooked threats to Arctic coasts amid climate change
As climate change rapidly transforms Arctic marine systems, the dramatic image of a polar bear struggling on a melting ice floe has become symbolic of the region's environmental crisis. But scientists argue that coastal Arctic ecosystems are undergoi.....»»

European Space Agency releases new strategy for Earth observation
The European Space Agency (ESA) has released its new Earth Observation Science Strategy, Earth Science in Action for Tomorrow's World. Responding to the escalating threats from climate change, biodiversity loss, pollution and extreme weather and the.....»»
