Solar Maximum 2025 is the expected peak of solar activity in Solar Cycle 25, characterized by heightened sunspots, solar ...

The robotic Solar Orbiter spacecraft has obtained the first images ever taken of our sun's two poles as scientists seek a deeper understanding of Earth's host star, including its magnetic field, its ...

Scientists believe the Sun’s magnetic field could reverse within our lifetime, a natural cycle that occurs roughly every 11 years. While this solar polarity shift is not dangerous, it can impact space ...

"We didn't know what exactly to expect from these first observations – the sun's poles are literally terra incognita,” Sami ...

We Earthlings see the sun every day of our lives—but gaining a truly new view of our star is a rare and precious thing. So ...

The magnetic field drives the formation of sunspots, cooler regions on the solar surface that appear as dark blotches. At the cycle's beginning, the sun has fewer sunspots. Their number increases as ...

The magnetic field drives the formation of sun spots – cooler regions on the solar surface that appear as dark blotches. At the cycle’s beginning, the sun has fewer sun spots.

An unexpectedly strong solar storm rocked our planet on April 23, 2023, sparking auroras as far south as southern Texas in ...

Why the poles matter Until now, all solar imagery has come from the equatorial perspective. The poles — critical to understanding the Sun’s magnetic field and solar cycle — remained hidden.
