Sun’s Puzzling Plasma Recreated in a Laboratory
For the first time, researchers have created a scale model of the twisting loops of the sun’s magnetic field.
Big Black Holes Found in the Smallest Galaxies
Tiny, dim “dwarf” galaxies have been found to hide gas-spewing black holes.
Wandering Space Rocks Help Solve Mysteries of Planet Formation
After an interstellar asteroid shot past the sun, scientists realized that there’s probably a lot of itinerant rocks out there.
The Sun Is Stranger Than Astrophysicists Imagined
The sun radiates far more high-frequency light than expected, raising questions about unknown features of the sun’s magnetic field and the possibility of even more exotic physics.
Dark Matter Gets a Reprieve in New Analysis
A strange glow coming from the Milky Way’s center was thought to be due to ordinary pulsars. But a new look at a years-old study shows that dark matter might still be responsible.
The Astronomer Who’d Rather Build Space Cameras
Jim Gunn shaped the theory of the evolution of the cosmos before building cameras and spectrographs for major observatories like the Hubble Space Telescope.

The astrophysicist Janna Levin reflects on the newly unveiled, first-ever photograph of a black hole.
How Artificial Intelligence Is Changing Science
The latest AI algorithms are probing the evolution of galaxies, calculating quantum wave functions, discovering new chemical compounds and more. Is there anything that scientists do that can’t be automated?
Galaxy Simulations Offer a New Solution to the Fermi Paradox
Astronomers claim in a new paper that star motions should make it easy for civilizations to spread across the galaxy, but still we might find ourselves alone.
