Five years into its mission, Solar Orbiter stuns again with this detailed view of the Sun. What you see is the Sun\u2019s million-degree hot atmosphere, called the corona, as it looks in ultraviolet light.\u00a0\u00a0<\/p>\n
Dive in and explore the hot plasma (charged particles) caught in the Sun\u2019s messy magnetic field. Can you spot the glowing coronal loops around active regions, and the darker, cooler filaments and prominences?\u00a0\u00a0<\/p>\n
Obtaining such a detailed image is no easy feat. On 9\u00a0March\u00a02025, at around 77\u00a0million\u00a0km from the Sun, the Solar Orbiter spacecraft was oriented to point to different regions across the Sun in a 5\u00a0x\u00a05 grid. At each pointing direction, the Extreme Ultraviolet Imager (EUI) instrument captured six images at high resolution and two wide-angle views.\u00a0<\/p>\n
The image you see here combines a whopping 200 individual images into the widest high-resolution view of the Sun yet. (See previous full Sun views here.)\u00a0<\/p>\n
Solar Orbiter is a space mission of international collaboration between ESA and NASA. The Extreme Ultraviolet Imager (EUI) instrument is led by the Royal Observatory of Belgium (ROB).\u00a0<\/i><\/p>\n
[Image description<\/i>: The Sun looks like a warm yellow sphere with a surface covered with glowing messy hair. The yellow glow extends to the edges of the image, with some regions brighter than others. Many bright yellow arcs stick out from a wide band around the Sun\u2019s equator. A darker region stands out across a roughly horizontal line near the Sun\u2019s south pole. The bright arcs and some darker material can also be seen around the Sun\u2019s edges.]\u00a0<\/p>\n
[Technical details<\/i>: This large image was assembled from images taken between 13:06 and 17:31\u00a0UTC (14:06\u201318:31\u00a0CET) on 9\u00a0March 2025 by Solar Orbiter\u2019s Extreme Ultraviolet Imager at a wavelength of 17.4\u00a0nanometres. Solar Orbiter was viewing the Sun from a latitude 11.4\u00b0 below the equator at a distance of around 77 million km. The final image is 12544\u00a0x\u00a012544 pixels in size, corresponding 6171.6\u00a0x\u00a06171.6 arc seconds or 2325.5\u00a0x\u00a02325.5 million km. The Sun, which has a diameter of 1.4\u00a0million\u00a0km, spans around 7505\u00a0pixels and 3692.6\u00a0arc seconds.]\u00a0<\/p>\n<\/p><\/div>\n<\/p><\/div>\n
