However, Lane and his colleagues tested an alternative idea called the timescape model, which suggests that the apparent acceleration could be a byproduct of cosmic structures like voids — vast ...

It remains the biggest cosmic haul from beyond the moon. The two previous asteroid sample missions, by Japan, yielded ...

Elementary particles were created. And, eventually, the cosmic flash dance left behind scars in the fabric of space-time. Physicists call them cosmic strings. Like stretch marks left on skin that ...

Scientists have detected cosmic waves that sound like chirping birds in an unexpected place NEW YORK -- Scientists have detected cosmic waves that sound like birds chirping in an unexpected place.

Scientists have come a step closer to understanding how collisionless shock waves -- found throughout the universe -- are able to accelerate particles to extreme speeds. Scientists have come a ...

Rather than relying on a cheek swab or a little blood, however, these cosmic DNA tests utilize tiny ripples in the fabric of spacetime called gravitational waves, first proposed by Albert Einstein ...

What is the structure of our physical reality? Physicists have long imagined space and time interweaving into “space-time”, the metaphorical fabric that underlies the cosmos. But there may be ...

Thick disk stars were born in an epoch when the Milky Way was furiously producing stars, a time astronomers call cosmic noon. “It was the most intense period of star formation ever.” ...

Stargazers are in for a cosmic treat as six planets align in a breathtaking display known as a planetary parade. This astronomical event is set to unfold across the night sky, showcasing Venus ...

The other tactic is to go back in time, all the way to near the beginning. The cosmic microwave background (CMB) radiation is the light emitted 379,000 years after the Big Bang. Before this time ...
