Even as the solar eclipse was mesmerizing millions, astronomers were training their space- and land-based telescopes on a far more violent astrophysical event.
The astrophysicist Andrea Ghez spent two decades proving that a supermassive black hole anchors the center of the Milky Way galaxy. Her new plan? Test what happens when things get too close.
The evolutionary biologist Jessica Flack seeks the computational rules that groups of organisms use to solve problems.
Spiders appear to offload cognitive tasks to their webs, making them one of a number of species with a mind that isn’t fully confined within the head.
A system of seven Earth-like exoplanets appeared to be unstable. Now their orbits have been rewritten in the music of the spheres.
For decades, researchers believed that violent supernovas forged gold and other heavy elements. But many now argue for a different cosmic quarry.
Elena Aprile now leads the world’s most sensitive dark-matter search. But before she could build her first detector, she had to make herself out of titanium.
The surprising discovery of a massive, Milky Way–size galaxy that is made of 99.99 percent dark matter has astronomers dreaming up new ideas about how galaxies form.
The astrophysicist Tracy Slatyer is searching for faint wisps of dark matter annihilating in the early universe — and perhaps in hiding places closer to home.
