Full spectrum of SBS 0335-052E. Green points: WISE. Blue points: Spitzer. Cyan points: Herschel. Black points: submm and radio. The IR part of the SED can be deconvolved into three components: a cold one of T₁ = 65 K (blue line), a warm one of T₂ = 160 K (green line), and emission from dust surrounding the still enshrouded star clusters (red line). Their sum is shown by dot-dashed line.
