Physics Breakthrough as AI Successfully Controls Plasma in Nuclear Fusion Experiment

by

Successfully achieving nuclear fusion holds the promise of delivering a limitless, sustainable source of clean energy, but we can only realize this incredible dream if we can master the complex physics taking place inside the reactor.   For decades, scientists have been taking incremental steps towards this goal, but many challenges remain. One of the … Read more

The Sun Has Erupted Non-Stop All Month, And There Are More Giant Flares Coming

by

The past few weeks or so have been a very busy time for the Sun. Our star has undergone a series of giant eruptions that have sent plasma hurtling through space. Perhaps the most dramatic was a powerful coronal mass ejection and solar flare that erupted from the far side of the Sun on February … Read more

A New Simulation of Mars’s Core Could Explain How It Lost Its Magnetic Field

by

Mars is a parched planet ruled by global dust storms. It’s also a frigid world, where night-time winter temperatures fall to minus 140 C (minus 220 F) at the poles. But it wasn’t always a dry, barren, freezing, inhospitable wasteland. It used to be a warm, wet, almost inviting place, where liquid water flowed across … Read more

Enigmatic High-Energy X-Rays Have Been Spied Coming From Jupiter

by

Jupiter has finally been observed spitting out X-rays in high-energy wavelengths. Emanating from the giant planet’s permanent auroras, and detected by NASA’s space-based X-ray telescope NuSTAR, the emissions are the most energetic light seen coming from any planet in the Solar System (aside from Earth).   The detection could shed light on the most powerful … Read more

Supercomputers Simulated a Black Hole And Found Something We’ve Never Seen Before

by

While black holes might always be black, they do occasionally emit some intense bursts of light from just outside their event horizon. Previously, what exactly caused these flares had been a mystery to science.    That mystery was solved recently by a team of researchers that used a series of supercomputers to model the details of black holes‘ magnetic … Read more

Jupiter’s auroras arise from a magnetic ‘tug-of-war’ with volcanic eruptions on its moon Io

by

Jupiter’s auroras are caused by a cosmic game of “tug-of-war,” fueled by volcanoes on the planet’s innermost moon, Io, new research suggests.  NASA’s Juno spacecraft and Hubble Space Telescope have revealed new evidence suggesting Jupiter’s rapid rotation and the release of sulfur and oxygen from volcanoes on Io — the most volcanically active world in … Read more

How a Magnetic ‘Tug-of-War’ With Io’s Volcanic Eruptions Creates Jupiter’s Auroras

by

Jupiter’s auroras – the lights that dance around its poles – are the most distinct in our solar system and over a thousand times brighter than Earth’s aurora. Now, a new study confirms that these otherworldly polar lights come from a unique source: space lava.   Jupiter‘s moon Io is the most volcanically active world in the solar … Read more

Strongest magnetic field did not produce exotic particles called magnetic monopoles

by

Researchers have used the strongest magnetic field ever measured to search for exotic particles called magnetic monopoles, but they came up empty Physics 2 February 2022 By Leah Crane Accelerator beam pipes at the Large Hadron Collider at CERN near Geneva, Switzerland Daniel Dominguez/CERN The strongest magnetic field ever measured anywhere in the universe has … Read more

Birds Use Earth’s Magnetic Field For ‘Stop Signs’ When They Migrate

by

Thanks to a combination of sensing the Earth’s magnetic field through vision and an in-built compass that allows them to orient themselves according to magnetic intensity, migratory birds don’t have much trouble finding their way.   Those biological gadgets, known as magnetoreception, allow birds to not only know which direction to head in on their first outbound migration but … Read more

Bird navigation: Slope of Earth’s magnetic field may be ‘stop sign’ for migrating species

by

Eurasian reed warblers migrate to sub-Saharan Africa each year – and they seem to use the slope of Earth’s magnetic field to judge when they have reached their European breeding grounds Life 27 January 2022 By Alex Wilkins A Eurasian reed warbler Shutterstock / Rafal Szozda Some birds rely on Earth’s magnetic field to navigate and … Read more
