On Nov. 29, 2022, the Shenzhou 15 mission launched from China’s Gobi Desert carrying three taikonauts – the Chinese word for astronauts.

Scientists have pushed the Milky Way's early history back more than 2 billion years: to less than 800 million years after the Big Bang.

Researchers in California achieved net energy gain in a thermonuclear fusion experiment. But how great of a breakthrough is this, really?

SpinLaunch has a working prototype successfully launching objects at 1,000 miles-per-hour, but will the laws of physics stand in the way?

This year, NIF reports that it has achieved "ignition" — that is, it has achieved slightly more fusion energy output than laser energy input.

The length of our day changes slightly over a six-year period. This recent discovery has perplexed scientists for about a decade.

The "upper limit" to the size of our planets is exceeded in other stellar systems, but double Jupiter's radius seems to be the limit.

The idea of atoms goes as far back as the ancient Greek philosopher Democritus in 400 B.C.E., who thought physics left no room for free will.

Scientists carried out an ultra-precise test of a core premise of Einstein’s modern theory of gravity. The theory stood up.

Interstellar distances are vast, and extremely advanced technology will be required if we (or aliens) want to visit other star systems.
