Based on observations made with the NASA/ESA Hubble Space Telescope, and obtained from the Hubble Legacy Archive, which is a collaboration between the Space Telescope Science Institute (STScI/NASA), the Space Telescope European Coordinating Facility (ST-ECF/ESA) and the Canadian Astronomy Data Centre (CADC/NRC/CSA).

The H alpha data come from the Local Group Galaxies Survey (Massey et al. 2006, Astrophysical Journal, 131, 2701) and are based on images taken with the Mayall 4-meter telescope at Kitt Peak National Observatory, National Optical Astronomy Observatory, which is operated by the Association of Universities for Research in Astronomy under cooperative agreement with the National Science Foundation.

The Spitzer Space Telescope World Wide Web Site is the result of a collaborative effort by the Education and Public Outreach team at the Spitzer Science Center (SSC), California Institute of Technology.
