The Sun has produced another powerful X-class solar flare, underscoring the heightened activity of Solar Cycle 25 and reminding scientists that our star is entering one of its most energetic phases in ...

The recent flurry of solar storms suggests the sun is in a period of maximal activity as part of its 11-year cycle. The active period is likely to continue over the next year, so more auroras could be ...

Our sun is about five times less magnetically active than other sunlike stars—effectively a special case. The reason for this could reside in the planets in our solar system, say researchers at the ...

The sun has become increasingly active since 2008, a new NASA study shows. Solar activity is known to fluctuate in cycles of 11 years, but there are longer-term variations that can last decades. Case ...

Has the Sun’s activity increased or decreased in the last few years? This is what a recent study published in The Astrophysical Journal Letters hopes to address as a team of scientists investigated ...

The colossal ball of hot gas at the center of our solar system will be lively for the next year, NASA said. The sun has reached its "solar maximum period," which is a state of heightened activity in ...

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 ...

BENGALURU: Artificial Intelligence has helped scientists unlock a century of the Sun’s history by analysing hand-drawn observations from the Kodaikanal Solar Observatory, turning fragile paper records ...
