"Monkey King" is first in a line of Chinese space missions focused on scientific discovery

The gigantic accelerator in Europe has produced hints of an exotic particle that defies the known laws of physics

A new breed of giants raises questions about how the biggest galaxies arise

The Dark Energy Survey is examining distant galaxies to figure out why space is expanding at an ever faster pace

Emerging evidence suggests that the first starlight to shine after the big bang’s flash came from distant suns that ranged from very large to incredibly huge

Is the big bang, and all that came from it, a holographic mirage from another dimension?

Newly discovered lobes stretch tens of thousands of light-years above and below the Milky Way's disk. Where did they come from?

The invisible dark matter particles that dominate the universe may come in strange and varied forms

Astronauts already skip ahead in time, but the laws of physics seem to forbid going backward—or do they?

As you dig into those mashed potatoes, be grateful the universe’s physical constants are so precise that a slight variation in any one would render that drumstick—and even your existence—impossible

A collision between the Red Planet and its innermost moon, Phobos, could create a Saturn-like field of debris
