The latest Swedish-led search for technosignatures in the form of Dyson spheres has again come up empty-handed. The two latest stellar candidates in the hunt for such hypothetical extraterrestrial technology have been eliminated ...
When engineers look to nature for inspiration, they often turn to living systems. The flight of birds has influenced aircraft design, gecko feet inspired new adhesives and lotus leaves led to the development of self-cleaning ...
Stanford researchers have offered an explanation for why some sizzling, lava-covered worlds nestled tightly around their stars can retain their atmospheres. At such close quarters, intense stellar radiation should strip away ...
Planets form from disks of gas and dust around young stars, but the gas needed for growth does not last forever. New observations from NASA's James Webb Space Telescope (JWST) now offer a new view of how this gas escapes ...
As wildfire smoke plumes travel thousands of miles, sunlight and atmospheric chemistry bleach their color, strip away their campfire aroma and add them to the mix of urban smog.
A NASA-led team hopes to take a shortcut to direct imaging of extrasolar Earth-like planets. The idea is to use what they call a hybrid telescope composed of an orbital starshade coupled with the next-generation extremely ...
Around 4.6 billion years ago, the solar system was little more than a giant ball of gas and dust. Over the next few million years, this "solar nebula" underwent a huge transformation, flattening into a disk of matter that ...
In the opening scene of American writer Kim Stanley Robinson's "The Ministry for the Future," a heat wave combined with a breakdown of the electrical grid in India kills 20 million people. The devastation causes the world's ...
Of Jupiter's four Galilean moons, Callisto is the one that gets the least attention. Io is constantly being resurfaced by volcanoes. Europa has a giant liquid water ocean. And Ganymede has its own magnetic field that interacts ...
Seismic waves produced by thunderstorms, called thunderquakes, can be used as a novel source for seismic imaging, according to a new study led by researchers at Penn State.
