Solar Storm Sparks Northern Lights Across Western Hemisphere on New Year's Eve
Solar storms on New Year’s Eve sparked breathtaking auroras across the US and Europe, with vibrant displays visible as far south as California, Austria, and Germany. Two coronal mass ejections (CMEs) struck Earth’s magnetic field, causing geomagnetic storms that reached G3 levels on January 1.

Chang'e-6 Mission Reveals Significant Reinforcement of Lunar Dynamo
The Chang'e-6 mission has provided crucial insights into the lunar dynamo’s evolution, revealing a surprising magnetic field strength of 5 to 21 microteslas (µT) around 2.8 billion years ago. This challenges previous assumptions that the lunar dynamo weakened after 3 billion years ago. The findings suggest that mechanisms such as a basal magma o...

Study Explores Sun’s Magnetic Field Changes and Solar Wind Acceleration
A study published in The Astrophysical Journal has shed light on how the Sun’s magnetic field influences solar wind acceleration. Using data from the Parker Solar Probe and Solar Orbiter, researchers observed that sharp magnetic switchbacks smooth out into gentler waves as they travel further from the Sun. This relaxation process transfers magnet...

Semi-Dirac Fermions Found in ZrSiS: Quasiparticles with Directional Mass Behavior
Researchers at Penn State and Columbia University identified semi-Dirac fermions, quasiparticles theorized 16 years ago, in ZrSiS crystals. These particles are massless in one direction but have mass in another. The findings, published in Physical Review X, were made using magneto-optical spectroscopy at the National High Magnetic Field Laboratory....

Aditya-L1 Records Coronal Mass Ejection, Reveals New Details on Solar Plasma Movement and Magnetic Activity
Aditya-L1, India’s first solar mission, observed a Coronal Mass Ejection on July 16, 2024. Researchers found that the event caused significant coronal dimming, increased turbulence, and solar plasma deflection due to magnetic fields. These insights, derived from VELC measurements, deepen our understanding of solar activity and its space weather i...

NASA’s Europa Clipper Probe Begins Deploying Science Instruments on Way to Jupiter
NASA's Europa Clipper spacecraft has begun deploying its key science instruments as it travels towards Jupiter. Launched in October 2023, the probe is on a 1.8-billion-mile journey to study Jupiter’s icy moon Europa. The recent deployment includes the magnetometer’s boom and radar antennas, crucial for studying Europa's magnetic field and subsu...

Solar Orbiter Sends High-Resolution Images of Sun’s Surface, Unveiling New Details
The Solar Orbiter spacecraft has sent back the sharpest images of the sun’s surface, captured from 74 million kilometres away. These high-resolution images reveal the sun’s dynamic surface features, including granular patterns and sunspots. The spacecraft’s instruments also provided detailed maps of the sun’s magnetic fields, shedding light...

New Research Reveals How Dynamo Reversals Impact Mars Magnetic Fields
Recent research in Nature Communications suggests that weak magnetic fields above Martian basins may stem from prolonged dynamo reversals, which reduce field strength over time. Through cooling models, scientists revealed that these reversing processes could account for Mars’s unique magnetic history, rather than indicating an early shutdown of t...

NASA is Sending Europa Clipper to Search for Aliens Near Jupiter's Moon
NASA is set to launch the Europa Clipper mission to explore Jupiter’s moon Europa in search of signs of life. The spacecraft will conduct a detailed investigation of the icy moon, where scientists suspect a liquid ocean exists beneath its frozen surface. Europa Clipper will analyse the moon’s surface, water plumes, and magnetic field to underst...
