Abstract: BLAST from the past Submillimetre galaxies at redshifts of 1 4 are thought to be precursors of the giant elliptical galaxies in the present-day Universe, as they are the only known objects with sufficiently massive star formation rates. A new extra-galactic survey from the Balloon-borne Large Aperture Submillimetre Telescope (BLAST) team, at 250, 350 and 500 µm has resulted in a 20-fold increase in the total number of galaxies observed in this wavelength range. The survey shows that the entire far infrared background derives from individual galaxies, with 70% of it from galaxies at z ≤ 1.2. These exploits are the subject of the documentary BLAST! ( http://www.blastthemovie.com ), being screened around the world as part of the International Year of Astronomy 2009 programme.
