BLAST :BLAST is a balloon-borne large-aperture, submillimetre telescope, which makes large area (1-200 square degree) surveys of Galactic and extragalactic targets. BLAST/BLASTPol :The Balloon-borne Large Aperture Submillimeter Telescope for Polarimetry (BLASTPol) was a suborbital experiment designed to map magnetic fields in order to study their role in star formation processes.id:BLAST/BLASTPol.a |
