From our viewpoint, it’s easy to imagine the Moon tracing out the Sun’s path along the ecliptic. For example, the Sun slides into the constellation Sagittarius on the winter solstice.

The European Space Agency's Solar Orbiter spacecraft returns first-ever data of the Sun collected from a 17-degree tilted orbit.

That line is called the ecliptic, and it looks similar to the arc-like path the Sun charts each day in the sky. But why do planets seem to follow the path of the Sun's movement?

The magnetic field drives the formation of sunspots, cooler regions on the solar surface that appear as dark blotches. At the ...

The official marker of the summer season arrives tonight. It's the summer solstice, which has been celebrated for thousands ...

The Sun's polar regions are pretty busy and chaotic places, but our newfound views of its south pole will help predict future solar activity.

The Ulysses mission, launched in 1990 and active until 2009, orbited the Sun at around 80 degrees relative to the ecliptic to make solar observations.

ESA has now released the first pictures of the sun’s south pole, taken between March, when the spacecraft was orbiting at an angle 15 degrees below the ecliptic plane, and today, when it reached ...

The assumption that when the sun sets on Madeira, its setting synchronizes with its rise on America, is subject to various deductions and additions, and modifications for the season of the year ...

The European Space Agency's Solar Orbiter captured the first-ever images of the sun's south pole in March, which were released this week.

Leaving the ecliptic is a costly, fuel-expensive maneuver for spacecraft, but it’s where Solar Orbiter excels: By the end of the mission, the spacecraft’s orbit will be tilted 33 degrees with ...

Solar Orbiter used momentum from its flyby of Venus on February 18 to push itself out of the ecliptic plane that contains Earth’s orbit around the Sun. Around a month later, the spacecraft was ...
