Hubble observed the Lagoon Nebula not only in visible light but
also at infrared wavelengths.
Not exact matches
Charged particles striking Saturn's upper atmosphere ionize hydrogen atoms and produce
infrared radiation, whereas related processes
also give off Saturnian auroras
at ultraviolet and radio
wavelengths.
[10] A compact radio source was found
at the centre of this nebula, and an
infrared point source has
also been found, but it has not been detected
at optical
wavelengths.
ALMA's observations,
at submillimetre
wavelengths, are
also impervious to the glare from the star that affects
infrared or visible - light telescopes.
They
also coated a porous gold film - which has a plasmonic response
at infrared wavelengths - in CTAC and used it as the substrate.
A number of similar black hole exploration methods have
also been proposed in optical /
infrared spectra so far, but one crucial problem is that emissions
at these
wavelengths are absorbed by interstellar dust particles although the more active black holes contain more dust particles.
HDST will therefore not just image new worlds, but will
also acquire spectra of their atmospheres
at visible (and in some cases out to near -
infrared)
wavelengths to search for signs that indicate a potential planet like our own.
We
also expect to see more
infrared radiation returning back to Earth
at these same
wavelengths.
Near
infrared light [which Myrrh calls reflective and according to him
also like visible light does no heating] starts
at about 1.2 watts per nm per square meter and by the point
at end of Near Infared
at 1400 nm, the per nm of
wavelength drops to under.5 watts per square meter per nm.
But the effect of CO2 gas warming is
also insignificant - in comparison between heating from CO2 and
infrared wavelength from the sun starting
at 2500 nm to 30,000 nm, it seems to me this entire
infrared spectrum could more significant as compared to any purported claim about warming due to CO2.
