Solar Orbiter speeds towards its next rendezvous with the Sun 🌞 #shorts
This sequence was taken by Solar Orbiter’s Extreme Ultraviolet Imager using the Full Sun Imager telescope, and shows the Sun at a wavelength of 17 nanometers. This wavelength is emitted by gas in the Sun’s atmosphere with a temperature of around one million degrees. The colour on this image has been artificially added because the original wavelength detected by the instrument is invisible to the human eye.

Solar Orbiter solves magnetic switchback mystery #shorts
Solar Orbiter has made the first ever remote sensing observation consistent with a magnetic phenomenon called a solar switchback – sudden and large deflections of the solar wind’s magnetic field. The new observation provides a full view of the structure, in this case confirming it has an S-shaped character, as predicted. Furthermore, the global perspective provided by the Solar Orbiter data indicates that these rapidly changing magnetic fields can have their origin near the surface of the Sun.

Can you spot the solar hedgehog? 🦔 #shorts
Solar Orbiter is a space mission of international collaboration between ESA and @NASA.
Solar Orbiter’s closest approach to the Sun, known as perihelion, took place on 26 March. The spacecraft was inside the orbit of Mercury, at about one-third the distance from the Sun to the Earth, and its heatshield was reaching around 500°C. But it dissipated that heat with its innovative technology to keep the spacecraft safe and functioning.

What is space weather?
Our star dominates the environment within our Solar System. Unpredictable and temperamental, the Sun has made life on the inner-most planets impossible, due to the intense radiation and colossal amounts of energetic material it blasts in every direction, creating the ever-changing conditions in space known as ‘space weather’.
