The Sun now



Image from the Extreme ultraviolet Imaging Telescope (EIT)

The Sun's hot atmosphere today
See the bright twisted clouds of hot gas, revealing storminess, and the dark, calm regions called coronal holes. These images, obtained with invisible ultraviolet light, give the scientists their routine weather maps of the Sun. Occasionally a solar flare appears, as a small, intensely bright flash. Different colours denote various ultraviolet wavelengths, each emanating from gas at a particular temperature - orange, 80 000 degrees, blue 1 000 000 degrees, green 1 500 000 degrees and yellow 2 500 000 degrees.
