Two of the biggest physics breakthroughs during the last decade are the discovery that wispy subatomic particles called neutrinos actually have a small amount of mass and the detection that the ...

Certain types of supernovae, or exploding stars, are more diverse than previously thought, a University of Arizona-led team of astronomers has discovered The results, reported in two papers published ...

The universe's expansion may actually have started to slow rather than accelerating at an ever-increasing rate as previously thought, a new study suggests. "Remarkable" findings published today in ...

Why is the expansion of our Universe accelerating? Twenty-five years after its discovery, this phenomenon remains one of the greatest scientific mysteries. Solving it involves testing the fundamental ...

Dark energy is one of the greatest mysteries in modern physics, comprising nearly 70% of the universe and causing its acceleration and the separation of galaxies over time. The concept emerged in the ...

For the three astrophysicists who won the Nobel Prize in physics today (Oct. 4), it was only a matter of when, not if, they would get the prize, their peers said. Their discovery that the universe's ...

The universe’s expansion might not be accelerating but slowing down, a new study suggests. If confirmed, the finding would upend decades of established astronomical assumptions and rewrite our ...

In 1998, scientists discovered that our universe expands with acceleration, and in order to explain this effect, the concept of dark matter was introduced. This is a special type of energy that fills ...

Alex Filippenko, a professor of astronomy at UC Berkeley and a member of the National Academy of Sciences and the American Academy of Arts and Sciences, will present “The Accelerating Universe and the ...
