Sun in different spectra in a single shot
Astronomers working with the Space Solar Dynamics Observatory (SDO), published a stunning collage of images taken by the telescope during this mission. Image was obtained by combining several images of the sun , made a telescope in different spectra.
Some of the waves in this image, such as strong ultraviolet radiation, the human eye can not be seen, so for better surveillance picture in this spectrum has been touched up.
Yellow picture, for example, was made with 5800 Å (angstroms). It shows the surface of the Sun. Usually the field generating this type of light, have a temperature of about 5700 degrees Celsius.
Thanks green filter on the image, we can see the superheated solar flares, which can reach temperatures of 6.3 million degrees Celsius. SDO usually takes them at 94 Å (angstroms).
All images that make up the finished picture, carefully analyzed and compared with other telescopes involved in supervision of our luminary. Through this work, scientists can better understand how particles move and heat inside or outside surface of the Sun.
