Astrophysics

Is the universe flat and infinite, or something more complex? We can’t say for sure, but a new search strategy is mapping out the subtle signals that could reveal if the universe has a shape.

Physicists discovered strange supersolids, constructed new kinds of superconductors, and continued to make the case that the cosmos is far weirder than anyone suspected.

Wherever astronomers look, they see life’s raw materials.

The giant holes in galaxies’ centers shouldn’t be able to merge, yet merge they do. Scientists suggest that an unusual form of dark matter may be the solution.

Astronomers are reveling in the James Webb Space Telescope’s discoveries about the formative epoch of cosmic history.

The largest-ever 3D map of the cosmos hints that the dark energy that’s fueling the universe’s expansion may be weakening. One community of theoretical physicists expected as much.

A long-awaited study of the cosmic expansion rate suggests that when it comes to the Hubble tension, cosmologists are still missing something.

Susan Clark is helping to unravel the mysterious workings of the Milky Way’s magnetic field, a critical missing piece of the galactic puzzle.

The outer layers of the sun’s atmosphere are a blistering million degrees hotter than its surface. The hidden culprit? Magnetic activity.
