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.

Acknowledgement: Flickr user c.claude.This little-known galaxy, officially named J04542829-6625280, but most often referred to as LEDA 89996, is a classic example of a spiral galaxy. 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 face-on spiral galaxy M83, a favourite target for amateurs, reveals rampant star formation in thousands of blazing young clusters in this image by the Hubble Space Telescope that also features scores of supernova remnants.
The Hubble Space Telescope searches for massive galactic clusters to learn more about gravitational lensing, the distortion and magnification of light from background, more distant bodies caused by a cluster’s enormous gravity.
This NASA/ESA Hubble Space Telescope image shows an isolated starburst galaxy named MCG+07-33-027. The galaxy lies some 300 million light-years away from us, and is currently experiencing an extraordinarily high rate of star formation — a starburst. Normal galaxies produce only a couple of new stars per year, but starburst galaxies can produce a hundred times more than that!
