Cosmology

Black holes break theories. These sites of extremely large masses in extremely small spaces invoke both of the behemoths of modern physics—general relativity (which rules over large masses) and quantum mechanics (which reigns in small spaces).

When the upgraded Large Hadron Collider restarts it will be capable of energies never before achieved, potentially unveiling novel particles and opening a window on the inner workings of the universe
 

Shortly after 7:30 am Eastern time this morning, a seven-year space voyage at last reached its final destination: NASA's Dawn mission entered orbit around Ceres, a small, icy world orbiting the sun between Mars and Jupiter.

Our understanding of this planet has evolved in step with scientific progress

Supermassive object found in the early universe tests theories of cosmic evolution

Each of the telescopes that the astronomers of the Event Horizon Telescope (EHT) are currently working to bring into their black-hole-observing, planet-size array is a special case.

Last night at the 87th Academy Awards, Eddie Redmayne won the Oscar for best actor for his portrayal of theoretical physicist and cosmologist Stephen Hawking in The Theory of Everything.

A new theory suggests the Higgs field varied in the early universe, offering matter a chance to split off from antimatter

The Planck satellite reveals the universe's first stars formed more than a hundred million years later than previously believed

Today is Valentine’s Day. In love? Or just the opposite? Express how you feel with physics-inspired Valentines—and anti-Valentines for those who perhaps aren’t huge fans of the holiday.

Some natural phenomena need few words to explain why they’re fascinating. Eclipses, transits, and phases in astronomy tend to fall into that category.

Cosmologist Kendrick Smith will present a free live Webcast on the quest to understand the origin of the universe
