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

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 "Golden Handle" appears each month when the sun illuminates a mountain range lining a vast impact crater. Saturday night ...

Altitude is an astronomy term that refers to the angle of a celestial body - in this case the Sun - above the horizon. At mid-day, the sun rises to an altitude of 56 degrees on April 1st in ...

Has the sun already reached solar maximum? New data suggests Solar Cycle 25 may have peaked earlier than expected. Find out what this means.

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.

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 ...
