Dust hides a universal starburst: When were the stars born? A new type of detector has seen powerful emission from dusty distant galaxies
Article Abstract:
A new camera has revealed that dust may be the most luminous matter in the Universe. Hughes and colleagues and Barger and colleagues have described what seem to be dusty young galaxies existing when the Universe was around an eighth of its present age. The Cosmic Background Explorer (COBE) first detected signs of powerful far-infrared background (FIB) in 1996, and the FIB can only come from dusty, star forming galaxies. Seven objects are reported to have been detected by the Submillimetre Common-User Bolometer Array (SCUBA).

A dusty pinwheel nebula around the massive star WR104
Article Abstract:
Images of the dust outflow around star Wolf-Rayet (WR) 104 indicate that the dust creates a spatially confined stream that follows exactly a linear spiral trajectory. For this star, the creation of the circumstellar dust is attributable to a binary companion. There is some evidence for brightness variations along the arm at a level of a few per cent of the peak, but the overall behaviour indicates a continuous and smooth dust-creation process.
