Solar Maximum 2025 is the expected peak of solar activity in Solar Cycle 25, characterized by heightened sunspots, solar flares, and coronal mass ejections. This peak is anticipated around mid to late ...

When the Sun reaches higher levels of activity, junk drifting in low Earth orbit loses altitude at an increased rate — and for the first time, scientists have measured that increase and identified ...

The Solar Spectacle On July 8, 2026, a remarkable and unexpected event unfolded in the cosmos. A massive solar filament eruption occurred on the Sun’s northeast side, capturing the attention of ...

Scientists monitoring the Sun have recorded a rare and unprecedented solar event that is changing how researchers understand solar activity and its influence on Earth. Using advanced space-based ...

Scientists have used artificial intelligence to unlock more than a century of hand-drawn solar observations from India's Kodaikanal Solar Observatory, creating one of the longest continuous records of ...

Solar activity as a research area focuses on the study of time-varying phenomena originating from the Sun’s magnetic field, including sunspots, flares, coronal mass ejections, solar wind variability, ...

When you look up at the sky on a sunny day, the Sun might seem like a bright spot, unchanging in the sky. But the Sun is a complex, dynamic celestial body, wrapped in electrical currents and magnetic ...

When solar activity reached an all-time low in 2008, astronomers reasonably figured the Sun was entering into a period of historically low activity. They were wrong. New research published September 8 ...

Scientists have proposed a surprising connection between solar flares and earthquakes. When solar activity disturbs the ionosphere, it may generate electric fields that penetrate fragile fracture ...
