Magnetic field

A huge new dataset could soon help unlock the mystery of fast radio bursts (FRBs). Within a few weeks, over 1,600 new signals were detected coming from one of the most well-studied sources, essentially ruling out a leading hypothesis on their origin.

Astronomers have detected a strange radio source from near the center of the Milky Way. The signal repeats seemingly at random and can’t be attributed to any known astronomical object, leading the team to consider that it may be something brand new.

German physicists have recorded the coldest temperature ever – 38 trillionths of a degree above absolute zero. The experiment involved dropping quantum gas and switching a magnetic field on and off to bring its atoms to an almost complete standstill.

As revolutionary as they could be, quantum computers still have a few issues, such as controlling more than a few dozen qubits. Now researchers have found a way to control potentially millions of qubits at once, by adding a crystal prism to the chip.

Astronomers are another step closer to solving the intriguing cosmic mystery of fast radio bursts. Five signals have been traced to their points of origin within the spiral arms of galaxies, narrowing down the list of suspects behind them.

Geologists have pieced together an uncertain part of Earth’s ancient history. A team in Australia has found new evidence that suggests the cycle of supercontinents forming and breaking up only started about two billion years ago.

Two years ago, astronomers revealed the first-ever direct images of a black hole. Now, the collaboration behind the historic image has released a new version that shows the polarization of the light around the object.

An ancient tree fossil has offered scientists a peek into a moment 42,000 years ago when the Earth’s magnetic field went haywire. The study paints a picture of environmental chaos, influencing everything from an increase in cave paintings to the extinction of the Neanderthals.

A crewed mission to Mars may be more practical thanks to a new rocket concept developed by Fatima Ebrahimi, a physicist at the US Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), that uses magnetic fields to generate thrust.

Exactly how some animals, such as birds, can detect magnetic fields remains a mystery. Now researchers in Japan may have found a crucial piece of the puzzle, making the first direct observations of live, unaltered cells responding to magnetic fields.

Space is an incredibly weird place. From extreme exoplanets to stars with strange fates, clues to an old mystery and the beginnings of a brand new one, here are 10 of the weirdest astronomical discoveries that blew our minds this year.

With an eye to improving quality of life for the elderly and frail, scientists at the National University of Singapore have discovered a molecule that can promote muscle health when subjected to weak magnetic fields.
