A viral claim suggests NASA detected 3I/ATLAS emitting pulse waves at 1,420 MHz, the same frequency SETI uses to search for extraterrestrial life.

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 Project, will help improve our understanding of the star ...

Here’s what Prof. Avi Loeb, a Harvard astrophysicist, has to say.

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, Earth was a very different place, with our early human ...

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 Correspondent Captured by the Hubble Space Telescope, the ...

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 those hundreds of thousands of years of our planet ...

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 numerous periods of glacial expansion. Scientists have ...
