A 2025 study published in the journal Space Weather suggests the minimum of the Centennial Gleissberg Cycle (CGC) has recently ended, marking a transition toward stronger solar cycles and rising solar irradiance that may persist through the mid-21st century.
An international team of astronomers led by Christ University, Bangalore, found that a massive spiral galaxy almost 1 billion light-years away from Earth harbors a supermassive black hole billions of times the sun’s mass which is powering colossal radio jets stretching 6 million light-years across.
Researchers at Los Alamos National Laboratory have found evidence linking lightning initiation in thunderstorms to cosmic ray showers, which could be the key to solving the mystery of what causes lightning to start in thunderstorms.
Researchers from the University of Pisa report the discovery of a large, multi-level subterranean structure beneath the Khafre Pyramid near Cairo, Egypt, using Synthetic Aperture Radar (SAR) Doppler Tomography. The findings have not yet been peer-reviewed but have drawn significant online attention due to the scale of the claims and their potential implications for our understanding of ancient history.
A new study published in Science Advances shows that Earth’s orbital cycles influenced the timing of Deccan Traps volcanic eruptions, contributing to environmental changes associated with the end-Cretaceous mass extinction, approximately 66 million years ago.
A new study suggests that supernova explosions occurring within 1 000 light-years of Earth may have contributed to past mass extinctions, after finding evidence linking two mass extinction events during Devonian and Ordovician periods to supernovae.
Breakthrough research led by a University of Canterbury team has resulted in a new tool, developed using artificial intelligence (AI), to improve the prediction of volcanic eruptions worldwide. This innovative system, designed to recognize seismic patterns, could become part of early warning systems for predicting future eruptions. To maximize its impact, the team plans to release the forecasting models as open-access resources, enabling volcano observatories worldwide to apply them in real-time monitoring and prediction.
As Japan marks the 14th anniversary of the 2011 Tohoku mega-quake—a magnitude 9.0 disaster that killed nearly 16 000 and triggered the Fukushima crisis—a new study from Tohoku, Hokkaido, and JAMSTEC researchers warns that strain building in the Chishima Trench off Hokkaido could unleash another magnitude 9.0 quake in the coming decades.
A new study by researchers at the University of Tsukuba examined the role of solar heat in earthquake activity. By analyzing seasonal variations in seismicity, correlations between solar activity and earthquakes, and the influence of atmospheric temperature on earthquake predictability, the study provides new insights into how solar-driven thermal effects may contribute to stress changes in the Earth’s lithosphere.
Scientists in Australia have identified what is now the world’s oldest known impact crater, a 3.5-billion-year-old geological structure that could reshape our understanding of Earth’s early history.
