As published this February, Juergen Steinacker, Laurent Pagani, and their colleagues from Grenoble and Pasadena detected unexpected mid-infrared radiation from the molecular cloud L 183 in the constellation Serpens Cauda ("Head of the snake"), at a distance of 360 light-years.
Instead, it revealed that coreshine is a widespread astronomical phenomenon: Roughly half of the cloud cores exhibited coreshine, mid-infrared radiation associated with scattering from dust grains in their densest regions.
The device works by comparing the temperature of the sky (based on the mid-infrared radiation
it emits) and the ambient temperature at ground level--large differences indicate clear skies.
Contrary to mid-infrared radiation
, near-infrared radiation (NIR) shows good transmission for HIPS specimens up to ~1 mm thickness.
10 [micro]m diameter, although using the mid-infrared radiation emanating from a synchrotron does offer significant advantages at high lateral spatial resolution.
26) Since a sample that absorbs mid-infrared radiation will also emit mid-infrared radiation, an analytically useful emission spectrum may also be recorded from a thin coating layer on a metallic substrate by emission spectroscopy.
Using a 4-meter telescope at the Cerro Tololo Inter-American Observatory in La Serena, Chile, Polomski and her colleagues have found that since 1997, the amount of mid-infrared radiation
emitted by dust surrounding the star has doubled.
