The 'brightest of all time' gamma-ray burst and its ordinary supernova
On 9 October 2022 a flash of high-intensity gamma rays was detected by NASA's Swift satellite coming from a galaxy 1.9 billion light-years away. Dubbed the "BOAT"—the "brightest of all time"—GRB 221009A was so exceptionally ...

Flip-flopping magnetic fields hint at a solution for puzzling fast radio bursts from space
Fast radio bursts—intense, milliseconds-long flashes of radio energy from outer space—have puzzled astronomers since they were first spotted in 2007. A single burst can emit as much energy in its brief life as the Sun ...

New discovery points the way to more compact fusion power plants
A magnetic cage keeps the more than 100 million degree Celsius hot plasmas in nuclear fusion devices at a distance from the vessel wall so that they do not melt. Now researchers at the Max Planck Institute for Plasma Physics ...

How space storms miscue train signals
In July 1982, train signals in Sweden misfired and erroneously turned red. The culprit, believe it or not, was a space storm that started 150 million kilometers (93 million miles) away.

How do superconductors work? A physicist explains what it means to have resistance-free electricity
The modern world runs on electricity, and wires are what carry that electricity to every light, television, heating system, cellphone and computer on the planet. Unfortunately, on average, about 5% of the power generated ...

Resistance in tokamak vessel walls can cause disruptive energy loss
Under certain conditions, the fusion devices known as tokamaks can suffer a sudden loss of energy to the vessel walls. Researchers call this energy loss process a disruption. One cause is a magnetohydrodynamic (i.e., conducting ...
