The probe completed its 27th closest approach to the Sun this March.

Every eleven years, the sun's magnetic field flips. Sunspots—dark, cooler regions on the sun's surface that mark intense magnetic activity and often trigger solar eruptions—appear at mid-latitudes and ...

During strong cycles, the sun’s total brightness at the solar maximum is about 0.1% higher than during its solar minimum, but when averaged out over the industrial period, the sun’s total brightness ...

Scientists have analyzed more than 40 years of astronomical data to uncover evidence that the sun's internal structure subtly changes from one solar cycle minimum to the next. Publishing their ...

At the center of our solar system, the sun is a constant force keeping planets in orbit, providing Earth with just the right amount of light and warmth for life and even governing our daily schedules.
