Herschel is sensitive to very long wavelength infrared light, allowing the telescope to pick up the faint thermal glow of dust just 25 °C above absolute zero.
Indeed, Earth is inside a very bright solar system: sunlight scattered by all the dust in the plane of Earth's orbit creates the zodiacal light radiating across the optical spectrum down to long - wavelength infrared.
Scan from the region of visible light towards the longer wavelengths of the electromagnetic spectrum and you'll find, sandwiched between microwaves and the infrared, a type of radiation that we have previously had little time for: terahertz rays, or T - rays.
Infrared wavelengths are longer than those of visible light, so the optics don't have to be as precise.

Since infrared has such a long wavelength, a larger mirror is needed to produce a quality image.
The Doppler effect causes them to create radiation in the longer - wavelength, infrared portion of the spectrum.
The «colours» are due to differences in the surface temperature of starsw1: hotter stars emit most of their light in the visible blue or ultraviolet regions of the electromagnetic spectrum, whereas cooler stars radiate at longer wavelengths, in the visible red or infrared regions (see Mignone & Barnes, 2011a).
The photons, having optical wavelengths, are degraded into longer wavelengths by dust absorption and reemission, so that the protostar is apparent to a distant observer only as an infrared object.
