Jason Steffen studies planets in other solar systems. His most famous work—OK, second-most famous work—was with NASA’s Kepler Mission, a survey of planetary systems. But you’re more likely to have heard of Steffen, a professor at the University of Nevada at Las Vegas, in a very different context: as a student of the airplane boarding process. Years ago, after waiting in yet another line on a jam-packed jetway, the physicist thought to himself, “There has to be a better way than this.”

Fast radio bursts, or FRBs – powerful, millisecond-duration radio waves coming from deep space outside the Milky Way Galaxy – have been among the most mysterious astronomical phenomena ever observed. Since FRBs were first discovered in 2007, astronomers from around the world have used radio telescopes to trace the bursts and look for clues on where they come from and how they’re produced.

The Physics World 2020 Breakthrough of the Year goes to Elham Fadaly, Alain Dijkstra and Erik Bakkers at Eindhoven University of Technology in the Netherlands, Jens Renè Suckert at Friedrich-Schiller-Universität Jena in Germany and an international team for creating a silicon-based material with a direct band gap that emits light at wavelengths used for optical telecommunications.

In March, when cases of COVID-19 began to overwhelm hospitals in the United States, I told my 90-year-old mother that she had to shelter in place. She lives alone in Los Angeles, and to keep her company, I FaceTimed her every night. In the role reversal that happens with time, I became the forever-worried, nagging parent, and she was the ever-doubting, defiant child.

From ultra-fast bullet trains to new-age medical equipment, superconductors could fundamentally change society. In the U.S. alone, about six percent of electricity passing through a typical power grid in a year is lost and becomes heat, which costs billions of dollars.

From ultra high speed levitating trains to lifesaving MRI machines, superconductors are key to some of the world’s most cutting edge technology. But they require extremely low temperatures to work and have remained too expensive for everyday use. Now that could be about to change. With superconductors that work at room temperature, our technological ability is posed to make a giant leap forward.

Magnetars, short for “magnetic stars,” are ultra-dense corpses of dead stars surrounded by intense magnetic fields. And according to new research, magnetars also appear to be the cause of at least some mysterious fast radio bursts, or FRBs, which astronomers have detected for more than a decade. So, by studying FRBs, scientists think they might be able to peel back the onion on magnetars.

For more than 13 years, astronomers have been trying to determine the source of extremely powerful radio bursts that can travel billions of kilometres through space but only last a fraction of a second.

For the first time ever, astronomers have linked an actual object to those mysterious radio bursts they’ve been detecting since 2007. The culprit in this case, as suspected, is a super-dense object known as a magnetar, but the finding has prompted an entirely new set of questions.

For around a decade, mysterious flashes from deep space have puzzled radio astronomers. The explosions of radio waves last for just a few thousandths of a second, and they appear to shine from galaxies billions of light years away—too far to get a good look at what’s making them. Researchers have detected about 120 such “Fast Radio Bursts” to date, and have come up with nearly half as many explanations. Theorists have floated ideas including exotic stars collapsing, neutron stars crashing into black holes, and even alien civilizations pushing starships around on energy beams.
