The Infrared Universe: Galaxies
The Hidden Maffei
Infrared light helps the study of galaxies that might otherwise be hidden from us. One such example is Maffei 2, a barred starburst galaxy that happens to fall behind our own Milky Way. In visible light, the thick clouds of dust within our own galaxy almost entirely obscure our view of it. Switching to longer infrared wavelengths lets the light pass through the murky dust to reveal this hidden gem.
