Massive spiral galaxy ISOHDFS 27

This photo is reproduced from an optical image of the distant galaxy ISOHDFS 27, obtained with the Hubble Space Telescope (HST). The angular size of this galaxy is about 7 arcsec, corresponding to about 130,000 light-years (40 kpc) at the distance of the galaxy, approx. 6,000 million light-years. The inclination of the galaxy's main plane to the line-of-sight is about 50°.

This image covers an area of approx. 7 x 8 arcsec 2 ; North is up, East is to the left. The present results are based on observations that were collected in visitor mode during August 18-20, 2000. For these observations, ISAAC was used in medium resolution mode (R ~ 5000) with a slit of 0.6 arcsec x 2 arcmin. The pixel scale is 0.146 arcsec/pix. The wavelength for the H-alpha is 1.0370 µm and the SZ band was used for the observations. The seeing was very good throughout the run (from 0.2 - 0.9 arcsec).
