Volcano-like rupture could have caused magnetar slowdown

On Oct. 5, 2020, the rapidly rotating corpse of a long-dead star about 30,000 light years from Earth changed speeds. In a cosmic instant, its spinning slowed. And a few days later, it abruptly started emitting radio waves.

Team uses quantum sensors to reveal how Weyl photocurrents flow

Quantum sensors can be used to reveal a surprising new mechanism for converting light into electricity in Weyl semimetals, Boston College (BC) Assistant Professor of Physics Brian Zhou and colleagues report in the journal ...

Astronomers use novel technique to find starspots

Astronomers have developed a powerful technique for identifying starspots, according to research presented this month at the 241st meeting of the American Astronomical Society.

BepiColombo and Solar Orbiter compare notes at Venus

The convergence of two spacecraft at Venus in August 2021 has given a unique insight into how the planet is able to retain its thick atmosphere without the protection of a global magnetic field.

A new approach to solving the mystery of dark energy

What is behind dark energy—and what connects it to the cosmological constant introduced by Albert Einstein? Two physicists from the University of Luxembourg point the way to answering these open questions of physics.

Earlier geomagnetic storm prediction wins us time to prepare

Scientists at the Skolkovo Institute of Science and Technology (Russia), together with colleagues from the Leibniz Institute for Astrophysics (Germany), the University of Graz & the Kanzelhöhe Observatory (Austria), the ...

Twisting up atoms through space and time

One of the most exciting applications of quantum computers will be to direct their gaze inwards, at the very quantum rules that make them tick. Quantum computers can be used to simulate quantum physics itself, and perhaps ...
