Citizen science discovers a new form of the northern lights

Working together with space researchers, Finnish amateur photographers have discovered a new auroral form. Named ‘dunes’ by the hobbyists, the phenomenon is believed to be caused by waves of oxygen atoms glowing due to a stream of particles released from the Sun. In the recently published study, the origins of the dunes were tracked to … Read more Citizen science discovers a new form of the northern lights

New research provides evidence of strong early magnetic field around Earth

Deep within Earth, swirling liquid iron generates our planet’s protective magnetic field. This magnetic field is invisible but is vital for life on Earth’s surface: it shields the planet from harmful solar wind and cosmic rays from the sun. Given the importance of the magnetic field, scientists have been trying to figure out how the … Read more New research provides evidence of strong early magnetic field around Earth

Magnetic storms discovered to originate much closer to Earth than previously thought

Magnetic storms are the primary drivers of extreme space weather around our planet, visible as the northern and southern auroral lights. Despite their importance and potential hazards to space and ground infrastructure, the process that powers storms has not been understood yet because they are far too dynamic and complex to study with single satellites. … Read more Magnetic storms discovered to originate much closer to Earth than previously thought

QUB’s scientist leads international team to crack 60-year-old mystery of Sun’s magnetic waves

A Queen’s University Belfast scientist has led an international team to the ground-breaking discovery of why the Sun’s magnetic waves strengthen and grow as they emerge from its surface, which could help to solve the mystery of how the corona of the Sun maintains its multi-million degree temperatures. For more than 60 years observations of … Read more QUB’s scientist leads international team to crack 60-year-old mystery of Sun’s magnetic waves

Physicists at Goethe University solve mystery surrounding photon momentum

Albert Einstein received the Nobel Prize for explaining the photoelectric effect: in its most intuitive form, a single atom is irradiated with light. According to Einstein, light consists of particles (photons) that transfer only quantised energy to the electron of the atom. If the photon’s energy is sufficient, it knocks the electrons out of the … Read more Physicists at Goethe University solve mystery surrounding photon momentum

The India-Asia collision as seen from Myanmar

Researchers from the University of Rennes 1 / CNRS (France), the University of Washington (USA) and the Universities of Yangon and Shwebo (Myanmar) have obtained new paleomagnetic evidence that the Burma Microplate was located close to the equator between 95 and 40 million years ago. These results, published in Nature Geoscience, support a double collision … Read more The India-Asia collision as seen from Myanmar

Astrophysicists link brightening of pulsar wind nebula to pulsar spin-down rate transition

Astrophysicists have discovered that the pulsar wind nebula (PWN) surrounding the famous pulsar B0540-69 brightened gradually after the pulsar experienced a sudden spin-down rate transition (SRT). This discovery, made by a group of astrophysicists led by GE Mingyu and LU Fangjun at the Institute of High Energy Physics of the Chinese Academy of Sciences, provides … Read more Astrophysicists link brightening of pulsar wind nebula to pulsar spin-down rate transition

Visualizing strong magnetic fields with neutrons

Researchers at the Paul Scherrer Institute PSI have developed a new method with which strong magnetic fields can be precisely measured. They use neutrons obtained from the SINQ spallation source. In the future, it will therefore be possible to measure the fields of magnets that are already installed in devices and thus are inaccessible by … Read more Visualizing strong magnetic fields with neutrons

Oceanic plateau formation by seafloor spreading implied by Tamu Massif magnetic anomalies

A new study published in Nature Geoscience concludes that Tamu Massif, thought to be the largest volcano in the world, is a different breed of volcanic mountain. The study analyzed magnetic field data over Tamu Massif, finding that magnetic anomalies (perturbations to the field caused by magnetic rocks in the Earth’s crust) are like those … Read more Oceanic plateau formation by seafloor spreading implied by Tamu Massif magnetic anomalies

Magnetic field morphology in interstellar clouds with the velocity gradient technique

On June 10, 2019, the British academic journal Nature Astronomy published a major breakthrough in the measurement of interstellar magnetic field: “Magnetic Field Morphology in Interstellar Clouds with the Velocity Gradient Technique”. The result came from the University of Wisconsin-Madison Alex Lazarian Professor’s research team, including UW-Madison physics graduate student Yue Hu and astronomy graduate student … Read more Magnetic field morphology in interstellar clouds with the velocity gradient technique
