Is it possible to understand the Universe without understanding the largest structures that reside in it? In principle, not ...

This implies a history where everything was closer together. 2) The properties of the cosmic microwave background radiation (CMB). This shows that the universe went through a transition from an ...

In the vast expanse of the universe, astronomers have just uncovered a colossal cosmic structure, breaking all previous ...

The cosmic microwave background (CMB) radiation is the light emitted 379,000 years after the Big Bang. Before this time the universe was filled with a dense, seething ocean of plasma, which is ...

Across cosmic history, powerful forces have acted on matter, reshaping the universe into an increasingly complex web of structures. Now, new research led by Joshua Kim and Mathew Madhavacheril at ...

Wolf 359’s extreme radiation and frequent X-ray flares make life-sustaining atmospheres on nearby planets highly unlikely, ...

calculated how much radiation an average star at cosmic noon would have experienced from its neighbors. They found that this background radiation was 1 million to 10 million times what stars ...

Scientists have detected cosmic waves that sound like chirping ... NASA's Van Allen Probes — heard the chirps from Earth's radiation belts at a closer distance than the newest detection.

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 ...

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 ...
