Infrared Radiation
Infrared light, commonly called IR, is a form of electromagnetic radiation that has a wavelength that is a longer than visible light. This energy band is most commonly associated with that of thermal radiation, that is the energy emitted by objects near room temperature.

Dwarf Galaxies
Dwarf Galaxies are sometimes hard to find, since they are small and dim. But these galaxies don't differ much from regular galaxies - whether it be spiral, elliptical or irregular - they are simply smaller versions of their parents. In fact, it is this key property of size that make them excellent for doing certain types of science, like indirect dark matter searchers. So let's explore dwarf galaxies!
