The Sun’s 11-year solar cycle is more than just a cosmic dance 🌞
It shapes space weather and impacts life on Earth! From dazzling auroras to powerful solar flares, its activity keeps us on our toes.

Join us on a unique video tour of the Sun’s mesmerising surface. Thanks to its innovative instrumentation and a ‘daring’ trajectory passing close to the Sun, ESA’s Solar Orbiter spacecraft has obtained the highest-resolution full views of the Sun’s surface to date.
Watching the Sun in visible light, Solar Orbiter reveals a grainy surface and dark sunspots. On the same day, the spacecraft mapped the Sun’s magnetic field, tracked how fast and in which direction scorching hot material on the surface is moving, and snapped a hypnotising image in ultraviolet light of the Sun’s upper atmosphere, the corona. All taken on the same day, the four new images shown in this video let us peel away the Sun’s many layers.
The images were taken when Solar Orbiter was less than 74 million kilometres from the Sun; being so close meant each high-resolution image only covers a small portion of the Sun. To obtain the full-disc views showcased in the video, 25 images were stitched together like a mosaic. The Sun has a diameter of around 8000 pixels in the full mosaics, revealing an extraordinary amount of detail.
