... On Nov 20, 1995, a suborbital rocket payload launched from Woomera, Australia obtained the first ultraviolet polarimetry of diffuse light in a galaxy. The Wide-Field Imaging Survey Polarimeter ("WISP") is a fast off-axis Schmidt telescope with ultraviolet polarimetric optics and a UV-sensitized CCD. ... In this poster we will compare the WISP data with visible and infrared images of the LMC, with the goal of delineating the geometric distribution of the diffuse dust in the LMC. ...

... This is a false color image of HR 4796A composed of visible and near-IR light (blue=STIS, green=1.71 micron, red=2.22 micron). It's red color is caused by dust grains that scatter light poorly in the visible and very efficiently in the near-IR. This images shows the debris disk around HD 61005, and a model of debris disk dust grains being blown by and interstellar wind. This work was a Goddard web feature (look there for a cool movie showing one of the models). ...

... The light baffles consist of the wind baffle that surrounds the telescope and doubles as a light baffle, the primary baffle that extends from the primary center-hole toward the secondary (left), the secondary baffle that extends from the perimeter of the secondary toward the primary (right), and the conical baffle that is suspended approximately halfway between the primary and secondary (middle). The wind baffle is covered with panels that are 25% porous to the wind. ...

. ATLAS is a project to image seven square degrees of sky, in two fields (CDF-S and ELAIS-S1), at radio wavelengths, to an rms of about 15 Jy, making it the widest deep radio survey aver attempted. The fields are chosen to cover the Spitzer Wide-Area IR Extragalactic Survey (SWIRE), and the radio images cut through the dust, to trace the cosmic history of AGN and star-forming galaxies.
