Berkeley - A bit of Earth-bound chemistry has led scientists at the University of California, Berkeley, to conclude that there is an unsuspected wind of low-energy cosmic ray particles blowing through ...

To help understand the emergence of life on Earth, some scientists are trying to unravel the cosmic carbon cycle. The interstellar chemistry of polycyclic aromatic hydrocarbons (PAHs)—a large family ...

The Pleistocene Epoch—with its glaciers, woolly mammoths, and Neanderthals—still looms large in Earth’s rearview mirror, having ended a mere 12,000 years ago. Now, a team of researchers posit that ...

Polycyclic aromatic hydrocarbons (PAHs) are important carriers of organic matter throughout the universe. As organic ...

Astrophysicists calculate the likelihood that Earth was exposed to cold, harsh interstellar clouds, a phenomenon not previously considered in geologic climate models. Around two million years ago, ...

It’s still a mystery how life got started on Earth – but maybe it didn’t start on Earth after all. A new Japanese study simulated the gigantic clouds of dust and gas that float around between the ...

Astronomers have measured the distribution of mass inside a dark filament in a molecular cloud with an amazing level of detail and to great depth. The measurement is based on a new method that looks ...

Astronomers have captured new, detailed maps of three nearby interstellar gas clouds containing regions of ongoing high-mass star formation. The results of this survey, called the Star Formation ...

Interstellar gas clouds vibrate like ringing bells. Those vibrations and the patterns they leave behind may help us understand the factors that control how many stars of different types are born deep ...

Astronomers describe the complex structure of the interstellar medium using a new mathematical method. The dispersion of interstellar turbulence in gas clouds before star formation unfolds in a ...

(Nanowerk News) Around two million years ago, Earth was a very different place, with our early human ancestors living alongside saber-toothed tigers, mastodons, and enormous rodents. And, depending on ...
