"Multiwavelength Milky Way" Poster Released

Volume 12, Number 3, September 1996
By David Leisawitz

The Astrophysics Data Facility has developed an educational poster called the "Multiwavelength Milky Way" that depicts the Galaxy at radio, infrared, optical, X-ray, and gamma-ray wavelengths. In particular, the poster contains images of the Galactic 21-cm and CO (J = 1 -> 0) line emission, and IRAS 12, 60, and 100 micron, COBE/DIRBE 1.25, 2.2, and 3.5 micron, Digital Sky Survey optical wavelength, ROSAT X-ray, and CGRO/EGRET gamma ray broadband emission. All of the data sets are publicly available, including those from the IRAS, COBE, ROSAT, and CGRO spacecraft.

Captions describe the Milky Way and what can be learned about the Galaxy from measurements made in each segment of the electromagnetic spectrum. The poster is intended to be an educational tool, one that will stimulate heightened awareness by laypersons of NASA's contribution to modern astronomy.

The poster was unveiled at the International Astronomical Union's Symposium 179 on "New Horizons from Multiwavelength Sky Surveys," held at the Space Telescope Science Institute in Baltimore, Maryland, during August 26-30, 1996. Approximately 450 copies of the poster were distributed to those attending. Copies will also be distributed at future meetings of the National Science Teachers' Association and of the American Geophysical Union and at the 189th meeting of the American Astronomical Society, which is to be held in Toronto, Ontario, January 11-16, 1997.

Drs. Seth Digel and David Leisawitz worked with graphic artists Sarah Geitz and Jay Friedlander to design the poster. Professor Geitz of Purdue University worked on the project during her visit to NASA Goddard as a NASA Summer Faculty Fellow. Dr. James Green, chief of the Space Science Data Operations Office, sponsored the project.

It is hoped that the poster will be displayed in secondary school classrooms, public libraries, and in the corridors of university astronomy departments. Requests for individual copies of the poster may be submitted to the NSSDC's Coordinated Request and User Support Office (see back page of this newsletter).
