ESA’s Solar Orbiter captured this hypnotizing time-lapse of the Sun as it heads inwards on its voyage of discovery starting from September 20 to October 10. It was captured using the Extreme Ultraviolet Imager (EUI) using the Full Sun Imager (FSI) telescope at a wavelength of 17 nanometers.
Why the 17 nanometer wavelength? This is the wavelength emitted by gas in the Sun’s atmosphere with a temperature of around one million degrees, but the color on this image was added in post processing because the original wavelength detected by the instrument is invisible to the human eye. Speaking of the Sun, did you know that researchers have found a way to turn water, CO2 and sunlight into jet fuel?
No products found.
Towards the end of the sequence, the image appears to jump slightly. This happens on the days that EUI was not returning data to Earth. The coloured bar at the top of the image shows the impressive amount of data collected in this period, together with these brief gaps in the data coverage,” said the European Space Agency.
