Hubble’s high-resolution Advanced Camera for Surveys captures fine detail in spiral galaxy LEDA 89996 in a view that measures just 0.84 x 0.82 arcminutes — approx. 1/72 x 1/72 degree.

The galaxy is much like our own galaxy, the Milky Way. The disc-shaped galaxy is seen face on, revealing the winding structure of the spiral arms. Dark patches in these spiral arms are in fact dust and gas — the raw materials for new stars. The many young stars that form in these regions make the spiral arms appear bright and bluish.
The galaxy sits in a vibrant area of the night sky within the constellation of Dorado (The Swordfish), and appears very close to the Large Magellanic Cloud — one of the satellite galaxies of the Milky Way.
The observations were carried out with the high resolution channel of Hubble’s Advanced Camera for Surveys. This instrument has delivered some of the sharpest views of the Universe so far achieved by mankind. This image covers only a tiny patch of sky — about the size of a one cent Euro coin held 100 metres away!
The Hubble Space Telescope is re-visiting six huge galaxy clusters, taking wide-angle views to help astronomers understand more about how galaxies were distributed across the early universe and what governed their evolution.
M64, more casually known as the “Black Eye” galaxy, is a familiar target for amateur astronomers, but it shines in all its glory – and earns its nickname – in images captured by the Hubble Space Telescope.
By using galaxies as giant gravitational lenses, an international group of astronomers using the Hubble Space Telescope have made an independent measurement of how fast the Universe is expanding. The newly measured expansion rate for the local Universe is consistent with earlier findings. These are, however, in intriguing disagreement with measurements of the early Universe.
