SUVI is a telescope that monitors the sun in
the extreme ultraviolet wavelength range.
The SDO can see
extreme ultraviolet wavelengths that are blocked by Earth's atmosphere, allowing it to look at the part of the corona where the temperature suddenly rises.
The other operated at
extreme ultraviolet wavelengths.
Not exact matches
The laser light that emerged from the frozen gas was in the
extreme ultraviolet range, with
wavelengths about 40 times shorter than the light that went in, they report today in the journal Nature.
Stuart Bowyer, from the University of California at Berkeley and a principal investigator of the EUVE, built an
extreme ultraviolet detector for the mission, which found four stars at these
wavelengths.
At the same time, an
extreme ultraviolet imager on SDO can follow small features at eight different
ultraviolet wavelengths that gauge temperatures from 20,000 ˚C to 1 million˚C.
Optical fibers generally are not able to transmit
ultraviolet light because the short
wavelength light can interact with dopants or impurities in the fibers, resulting in so - called «solarization» damage and
extreme losses of beam intensity.
The new tool will soon be able to generate pulses of high - energy light, with a
wavelength of 60 nanometers, in the
extreme ultraviolet segment of the spectrum.
These tools, however, produce nothing close to the angstrom - level (tenth of a nanometer) resolution of a new type of microscope that uses femtosecond pulses of
extreme ultraviolet light (EUV)-- the same
wavelength light to be used for sub-10 nanometer semiconductor lithography.]
Furthermore, KELT - 9b receives ~ 700 times more
extreme ultraviolet radiation (
wavelengths shorter than 91.2 nanometers) than WASP - 33b, leading to a predicted range of mass - loss rates that could leave the planet largely stripped of its envelope during the main - sequence lifetime of the host star.
Each image shows a different
wavelength of
extreme ultraviolet light that highlights a different temperature of material on the sun.
The shortwave
extreme ultraviolet flux is much higher in the distant past, which could pose problems for early Mars to develop a very dense CO2 atmosphere early on for example, since C and O could escape from Mars early in its history (driven by these energetic
wavelengths).
The lone active region visible on the sun put on a fine display with its tangled magnetic field lines swaying and twisting above it (Apr.24 - 26, 2018) when viewed in a
wavelength of
extreme ultraviolet light.
