Noctilucent clouds were once thought to be a fairly modern phenomenon. A team of researchers recently calculated that Earth and the entire solar system may well have passed through two dense ...

Beyond the local interstellar clouds and their wispy clumps of hydrogen and helium atoms in the form of gas and dust, the ...

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 ...

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, ...

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 suggest this cold, dense cloud compressed our sun’s protective field between two and three million years ago, leaving the Earth exposed to cosmic material Christian Thorsberg Daily ...

The world is coping with the effects of a warming climate, but a few thousand years ago, Earth had the opposite problem. During the Pleistocene Epoch, often called the Ice Age, Earth was subject to ...

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 ...

A team of astronomers, led by researchers from the Shanghai Astronomical Observatory (SHAO), has uncovered an unexpected and intricate network of tangled, supersonic filaments within a ...

Astronomers used observations from the James Webb Space Telescope (JWST) to achieve the darkest ever view of a dense interstellar cloud. These observations have revealed the composition of a virtual ...

Earth may have been exposed to interstellar clouds which may have changed the chemistry of the planet's atmosphere and led to the development of multiple ice ages, researchers suggest. Astrophysicists ...
