Cosmogenic radionuclides, such as 14C and 10Be, are produced in Earth’s atmosphere by interactions with cosmic rays and offer a unique window into past solar variability. Their deposition in natural ...

A century of solar observations from Kodaikanal Solar Observatory and modern satellite data reveal patterns in the Sun’s polar magnetic activity, aiding predictions of future solar cycles.

Solar activity, manifested primarily through sunspots, solar flares and coronal mass ejections, has long influenced both the near-space environment and terrestrial systems. Over millennia, variations ...

The sun has become more and more active over the last 16 years, in a turn that surprised scientists and could affect space weather and technology on Earth, NASA announced this week. A new research, ...

NASA’s Parker Solar Probe completed its 27th close approach to the Sun in March 2026, gathering data from the corona to ...

NASA’s Parker Solar Probe completed its 27th close approach to the Sun on March 11, again matching its record distance of 3.8 ...

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 ...

How can astronomers observe and study the Sun’s activity in the most efficient way despite the Sun and Earth orbiting each other at different speeds? This is what a recent study published in Astronomy ...

Add Yahoo as a preferred source to see more of our stories on Google. The Sun seems like a perfectly reliable, unchanging presence in the daytime sky, but it’s not. Intense heat and pressure in its ...

Research by university scientists suggests that solar flares may be far hotter than previously believed, offering new insights into the Sun’s behavior. The findings, recently published in the ...

A study published in The Astrophysical Journal Letters, introduces a newly defined "filament channel" function. This new function provides a novel theoretical foundation for predicting solar eruptions ...
