NASA released October 10 solar active regions using a composite picture image is created, the figure of the sun looks like a giant Halloween pumpkins.
Integrated media reported on October 11, NASA (NASA) 10 issued a use of solar active regions of the composite picture image is created, the figure of the sun looks like a giant Halloween pumpkins.
NASA said on its Web site describes the active region appears brighter, because these regions emit more light and energy. These areas marked in this part of the solar atmosphere (corona), and there is a fierce and complex field.
Reported that NASA uses images from two different wavelengths of light, the observed kinetics by Solar Observatory. This two light a group of 171 angstroms, a group of 193 angstroms, in general are golden and yellow.
NASA said light 171 angstroms can show the corona at the sun quiet. 193 shows a higher coronal temperature region.
In the EUV wavelength of 171 to capture images.
In the EUV wavelength of 193 to capture images.
In the EUV wavelength of 304 to capture images.
In the EUV wavelength of 335 to capture images.
