Since Kepler's laws of motion dictate that celestial bodies orbit more slowly when farther from the sun, we are now moving at ...

But by tilting the Solar Orbiter's orbit out of that plane, the ESA was able to reveal the sun from a brand new angle. The process began in February 2025 when the Solar Orbiter passed closely by ...

The sun cycles between periods of low and high activity over 11 years. The maximum can bring stunning light displays and offer NASA scientists unique research opportunities.

The European Space Agency's Solar Orbiter, which launched in 2020 from Cape Canaveral, captured the first-ever images of the sun's south pole.

This collage shows Solar Orbiter's view of the sun's south pole on 16–17 March 2025, from a viewing angle of about 15° below the solar equator. Credit: ESA & NASA/Solar Orbiter/PHI, EUI & SPICE ...

A solar flare is a burst of radiation on the sun, according to NASA. They are the most powerful explosions in the solar system, with the biggest ones having as much energy as a billion hydrogen bombs.

The sun has a "Hale Cycle," a complete magnetic cycle spanning two solar cycles, or 22 years, representing the time it takes for our home star's magnetic field to return to its original state ...
