For decades, astronomers debated whether a particular smudge was close-by and small, or distant and huge. A new X-ray map supports the massive option.

Over the past two years, astronomers have rewritten the story of our galaxy.

Physicists plan to leave no stone unturned, checking whether dark matter tickles different types of detectors, nudges starlight, warms planetary cores or even lodges in rocks.

In 2020, researchers reported that they had created a room-temperature superconductor. That paper has now been retracted.

Renormalization has become perhaps the single most important advance in theoretical physics in 50 years.

Cosmologists have concluded that the universe doesn’t appear to clump as much as it should. Could both of cosmology’s big puzzles share a single fix?

Physicists have identified an algebraic structure underlying the messy mathematics of particle collisions. Some hope it will lead to a more elegant theory of the natural world.

An 18th-century physicist first predicted the existence of a chorus of atmospheric waves that swoop around Earth. Scientists have finally found them.

Detailed computer simulations have found that a cosmic contraction can generate features of the universe that we observe today.
