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 ...

Scientists believe Earth may have briefly lost protection from the sun around two million years ago, left to endure the extreme environment of interstellar space as the solar system passed through a ...

Can the fastest brightening ever recorded in a comet rewrite what we know about interstellar visitors? As Comet 3I/ATLAS ...

Interstellar invader Comet 3I/ATLAS is still full of surprises — an unexpected brightening has scientists baffled ...

During that close approach, scientists were surprised to note that 3I/ATLAS brightened much faster than they anticipated.

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, ...

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 ...

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 ...

The interstellar comet 3I/ATLAS will make its closest pass to the sun on Oct. 30, and various spacecraft will be watching, ...

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 ...

Is life a highly improbable event, or is it rather the inevitable consequence of a rich chemical soup available everywhere in the cosmos? Scientists have recently found new evidence that amino acids, ...

Astronomers have discovered the first chiral molecule in interstellar space (Science 2016, DOI: 10.1126/science.aae0328). The discovery of propylene oxide in an interstellar cloud sets the stage for ...
