When people think of asteroids, they tend to picture rare, civilization-ending impacts like those depicted in movies such as "Armageddon." In reality, the asteroids most likely to affect modern society are much smaller. While ...
We all know that stars radiate light and much more. But radiation belts can also surround many other celestial bodies, such as planets. These belts do not generate particles themselves—the belts receive them from nearby stars—but ...
Four years ago, NASA purposely smashed a spacecraft into a small asteroid to see if they could deflect it—a test to prove humanity could protect Earth from threatening space rocks.
Earth is not infinite. Pollution beyond certain levels threatens the climate and ecosystems. To prevent this, scientists have proposed planetary boundaries, defining the safe operating limits of the Earth system. A KAIST ...
Planetary systems such as our solar system take hundreds of millions of years to evolve. Since humanity has only existed for a sliver of that time, astronomers have only observed planetary systems at birth or, more often, ...
An international team of astronomers has discovered a distant planetary system that challenges long-standing theories of how planets form. Across our galaxy, astronomers routinely observe a characteristic pattern in planetary ...
A global team of astronomers, led by the University of Warwick, have used a European Space Agency (ESA) telescope to discover a planetary system that turns our understanding of planet formation upside down, with a distant ...
Using HARPS and HARPS-N spectrographs, astronomers have observed a nearby K-type star designated HD 176986, known to host two super-Earth exoplanets. The observations resulted in the discovery of another planet in the system ...
Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of stars are equally common. Physicists can now explain the dearth.
The adverse health impacts associated with emissions across the full life cycle of plastics could double by 2040 unless immediate action is taken, new research suggests. The study identified health harms at every stage of ...
