How particle detectors capture matter’s hidden, beautiful reality
Old and new detectors trace the whirling paths of subatomic particles.

A bounty of potential gravitational wave events hints at exciting possibilities
Of about 1,200 possible events, most are probably false alarms, but some could be ripples in spacetime that are especially hard to spot.

Black holes born with magnetic fields quickly shed them
New computer simulations show one way that black holes might discard their magnetic fields.

With Steven Weinberg’s death, physics loses a titan
The Nobel laureate advanced the theory of particles and forces, and wrote insightfully for a wider public.

Scientists spotted an electron-capture supernova for the first time
A flare that appeared in the sky in 2018 was an electron-capture supernova, a blast that can occur in stars too small to go off the usual way.

An atomic clock that could revolutionize space travel just passed its first test
The most precise clock ever sent to space successfully operated in Earth’s orbit for over a year.

This moon-sized white dwarf is the smallest ever found
A newfound white dwarf is the smallest and perhaps the most massive known, and spins around once every seven minutes.

Gravitational waves reveal the first known mergers of a black hole and neutron star
For the first time, LIGO and Virgo have detected long-anticipated gravitational waves from a black hole merging with a neutron star.

A proposed ‘quantum compass’ for songbirds just got more plausible
Quantum physics could be behind birds’ magnetic sense of direction, new measurements indicate.

Dark matter may slow the rotation of the Milky Way’s central bar of stars
A method akin to studying a tree’s rings revealed the history of a slowdown of the rotating bar of stars at the heart of the Milky Way galaxy.
