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.....»»

Five space mysteries Proba-3 will help solve
ESA's Proba-3 will be the first mission to create an artificial total solar eclipse by flying a pair of satellites 150 meters apart. For six hours at a time, it will be able to see the sun's faint atmosphere, the corona, in the hard-to-observe region.....»»
Team links comet water to Earth"s oceans
Researchers have found that water on Comet 67P/Churyumov–Gerasimenko has a similar molecular signature to the water in Earth's oceans. Contradicting some recent results, this finding reopens the case that Jupiter-family comets like 67P could have h.....»»
NEOWISE, the NASA mission that cataloged objects around Earth for over a decade, has come to an end
The NASA project NEOWISE, which has given astronomers a detailed view of near-Earth objects—some of which could strike the Earth—ended its mission and burned on reentering the atmosphere after over a decade......»»
Researchers finally identify the ocean’s “mystery mollusk”
It's a nudibranch, but so distantly related that it gets its own phylogenetic family. Some of the most bizarre lifeforms on Earth lurk in the deeper realms of the ocean. There was.....»»
Evidence of primordial black holes may be hiding in planets, or even everyday objects here on Earth
Imagine the formation of a black hole and you'll probably envision a massive star running out of fuel and collapsing in on itself. Yet the chaotic conditions of the early universe may have also allowed many small black holes to form long before the f.....»»
Proba-3: Flying two spacecraft is harder than one
What's harder than flying a single satellite in Earth orbit? Flying two—right beside each other, at proximities that would normally trigger collision avoidance maneuvers......»»
Biomolecules under deep Earth conditions help refine primordial soup theory for possible origins of life
A collaborative research team has made significant progress in studying the abiotic synthesis and stability of biomolecules in C-H-O-N fluids under deep Earth conditions......»»
Getting to the bottom of Cenozoic deep-ocean temperatures
Understanding ancient ocean temperatures—particularly from the Cenozoic era (the past 66 million years), in which Earth experienced dramatic climate shifts—helps scientists reveal more about the planet's past climates......»»
Clay minerals: Researchers observe for the first time how sediment particles align during deposition
Clay minerals are a major constituent of the Earth's surface and are mainly found in the sediments of lakes, rivers and oceans. The properties of clay and claystone depend on how the tiny sediment particles are orientated. Using the European Synchrot.....»»
Bring back the bison: Indigenous ranchers in Texas push for buffalo conservation
The sun hangs low over the horizon as a black pickup crunches the gravel road. As the truck comes to a stop, bright dark eyes stare nervously out of its trailer, whites bulging as a thick furry neck twists about for a better look......»»
Fruit trees and "generational learning" turn El Cajon into a parrot paradise as temperatures drop
The squawking usually begins just past 4:30 p.m. this time of year, when the sun begins to hang low in the sky......»»

Conceptual model illuminates role of polar ice sheets in climate tipping points
Polar ice sheets are critical for climate projections, according to new research published Nov. 27 in the journal Nature Communications Earth & Environment. Improving understanding of the Greenland and Antarctic ice sheets is essential for reducing t.....»»
Researchers find a possible solution to the cosmic ray muon puzzle
Scientists have a problem with cosmic rays—they produce too many muons at the Earth's surface. Cascades of muons are byproducts of high-energy cosmic rays as they collide with nuclei in the upper atmosphere, and scientists see more muons at Earth's.....»»
