   The Extreme Ultraviolet Explorer (EUVE) is a NASA-funded astronomy project observing in the relatively unexplored 70-760 band. Its astro-nomical science payload was designed and built at the UC Berkeley Space Sciences Laboratory. The package consists of  three grazing-incidence scanning telescopes and an EUV spectrometer/deep-sky instrument. This payload is attached to a Multi-Mission Modular spacecraft.

   Observing in the extreme ultraviolet is particularly difficult because, at these wavelengths, light is typically absorbed by rather than reflected by con-ventional telescope mirrors. (EUV light is absorbed by all but the thinnest of materials.) Ordinary lenses, filters, and transmission gratings cannot be used  for EUV observation.

   Dr. Hawkins will describe the exceptional materials used to create the grazing-incidence mirrors and grating surfaces. She will also discuss the five primary science goals of the EUV sky scan.

  • Conducting an all-sky, 70-760 survey .
  • Carrying out a deep EUV survey along the ecliptic.
  • Performing spectroscopy observations.
  • Initiating an interstellar medium study .
  • Testing whether compelling science can be done with increased sensitivity.

From the correct vantage point, the Milky Way may closely resemble NGC 1232. The spiral morphology of both galaxies is believed to be quite similar. NGC 1232 is located approximately 65 million light-years distant, in Eridanus (R.A. 3h 9.48m, Dec. -20.35/epoch 2000). (W. M. Keck Observatory)
