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!
On 24th January 2015, three of Jupiter’s Galilean moons were in simultaneous transit across the face of their parent planet. The Hubble Space Telescope captured this rare event in amazing detail.
Eta Carinae is the most luminous and massive stellar system within 10,000 light-years of Earth. A long-term study led by astronomers at NASA’s Goddard Space Flight Center used satellites, ground-based telescopes and theoretical modelling to produce the most comprehensive picture of Eta Carinae to date.
As we celebrate 25 years of the Hubble Space Telescope, here’s another gem from the archives. The binary star system known as eta Carinae, part of the Trumpler 16 open cluster in the Carina Nebula.
