How to keep Earth from being cooked by the ever-hotter Sun
Here are two options for future humans to keep us in the habitable zone. I’d wager a guess that we are, as a species, rather fond of our home planet (our wanton carbon emissions notwithstanding). But the ugly truth is that the Eart.....»»
Simulation sheds light on Earth"s magnetic field generation while advancing neuromorphic computing
How does the Earth generate its magnetic field? While the basic mechanisms seem to be understood, many details remain unresolved. A team of researchers from the Center for Advanced Systems Understanding at the Helmholtz-Zentrum Dresden-Rossendorf, Sa.....»»
Planning a holiday? Three ways to reduce your carbon footprint
These holidays, planet Earth looks likely to be hotter than ever before. Research found that in 2024, global temperatures temporarily rose 1.5°C higher than the average from 1850 to 1900—a pre-industrial time when the first global temperatures wer.....»»
Does the exoplanet TRAPPIST-1 b have an atmosphere after all?
TRAPPIST-1 b is one of seven rocky planets orbiting the star TRAPPIST-1, located 40 light-years away. The planetary system is unique because it allows astronomers to study seven Earth-like planets from relatively close range, with three of them in th.....»»
Scientists struggle to explain record surge in global heat
The world has been getting hotter for decades but a sudden and extraordinary surge in heat has sent the climate deeper into uncharted territory—and scientists are still trying to figure out why......»»
Completing the "timetree" of primates: A new way to map the evolutionary history of life on Earth
In a new article published in Frontiers in Bioinformatics, biologists Dr. Jack M Craig, Dr. Blair Hedges, and Dr. Sudhir Kumar, all at Temple University, have built an evolutionary tree that encompasses 455 primates, every species for which genetic d.....»»
How to find a comet before it hits Earth
How do you find a comet that could pose a threat to Earth but hasn't passed our planet in the last 200 years or more? You look for its footprint......»»
Seabed seismographs unlock mysteries of longest runout sediment flows
Durham University scientists have made a groundbreaking discovery in marine geoscience, revealing unprecedented insights into the dynamics of Earth's longest runout sediment flows......»»
Southern states brace for water changes, report finds
Water is everywhere. It falls freely from the sky and flows across the earth. Humans are inextricably connected to water and to forests. Changes in land use, forest conditions, and climate affect water – with consequences for drinking water treatme.....»»
Rising desertification shows we can"t keep farming with fossil fuels
Three-quarters of Earth's land has become drier since 1990. Droughts come and go—more often and more extreme with the incessant rise of greenhouse gas emissions over the last three decades—but burning fossil fuels is transforming our blue planet......»»
Observations suggest sun-like stars emit superflares once per century
There is no question that the sun is a temperamental star, as this year's unusually strong solar storms show. Some of them led to remarkable auroras even at low latitudes. But can our star become even more furious?.....»»
Could the ESA"s PLATO mission find Earth 2.0?
Currently, 5,788 exoplanets have been confirmed in 4,326 star systems, while thousands more candidates await confirmation. So far, the vast majority of these planets have been gas giants (3,826) or Super-Earths (1,735), while only 210 have been "Eart.....»»
Early Earth"s oceans of magma may have accelerated the moon"s departure
The Earth and moon have been locked in a gravitational dance for billions of years. Each day, as the Earth turns, the moon tugs upon the oceans of the world, causing the rise and fall of tides. As a result, the Earth's day gets a little bit longer, a.....»»
NASA"s Lucy spacecraft prepares for second Earth gravity assist
On Dec. 12, at 11:15 p.m. EST, NASA's Lucy spacecraft, currently in a two-year orbit around the sun, will skim Earth's atmosphere, passing only about 220 miles (360 kilometers) above the surface. This close flyby will result in a "gravity assist," pu.....»»
Eyes on the sun: Naked thallium-205 ion decay reveals history over millions of years
The sun, the essential engine that sustains life on Earth, generates its tremendous energy through the process of nuclear fusion. At the same time, it releases a continuous stream of neutrinos—particles that serve as messengers of its internal dyna.....»»
An interstellar visitor helped shape the orbits of the planets
The orbits of the planets around the sun have been the source for many a scientific debate. Their current orbital properties are well understood but the planetary orbits have evolved and changed since the formation of the solar system......»»
Cosmic rays" vast energy traced to magnetic turbulence
Ultra-high energy cosmic rays, which emerge in extreme astrophysical environments—like the roiling environments near black holes and neutron stars—have far more energy than the energetic particles that emerge from our sun. In fact, the particles.....»»
New set of human rights principles aims to end displacement and abuse of Indigenous people
For more than a century, conservationists have worked to preserve natural ecosystems by creating national parks and protected areas. Today the Earth faces a global biodiversity crisis, with more than 1 million species at risk of extinction. This make.....»»
Sentinel-1C captures first radar images of Earth
Less than a week after its launch, the Copernicus Sentinel-1C satellite has delivered its first radar images of Earth—offering a glimpse into its capabilities for environmental monitoring. These initial images feature regions of interest, including.....»»
Plans to stabilize Earth"s climate rely on emerging carbon removal technology—we need to get moving, say researchers
Global carbon emissions from fossil fuels continue to rise and 2024 is likely to be the world's hottest year on record......»»
Jupiter will be at its biggest and brightest this weekend. Here’s how to see it
There's a special chance to see Jupiter in the sky this weekend as it comes closest to Earth......»»
