Astronomers have been confounded by recent evidence that the universe expanded at different rates throughout its life. New ...

Astrophysicists have presumed for nearly a century that the universe will just keep expanding for all eternity, driven by an ...

“This year’s Nobel laureates in physics have painted a picture of a universe far stranger and more wonderful than we ever could have imagined.” Theoretical physicist Ulf Danielsson from Uppsala ...

Nobel Laureate in Physics Professor Serge Haroche is among dozens of world-renowned scientists attending the international ...

Cosmologists face a dilemma. The rise of quantitative cosmology, exemplified by the release of new data in March on the cosmic microwave background from the WMAP satellite (see pp16-19; print version ...

For centuries, cartographers have sought to map Earth’s land masses and seas to better understand the world and their place in it. Now, astrophysicists have taken a major step toward doing the same ...

A theory that unites quantum mechanics and general relativity claims that there was no first moment in time, but it still agrees with the predictions of classical cosmology. It's in the stars One of ...

Of all the known particles in the universe, only photons outnumber neutrinos. Despite their abundance, however, neutrinos are hard to catch and inspect, as they interact with matter only very weakly.

THIS YEAR’S Nobel prize for physics was split two ways, but both halves went for discoveries beyond Earth. One was for a finding that is, by astronomical standards, quite close by—a planet going ...
