NASA and the European Space Agency (ESA) have released the sharpest and biggest image ever taken of the Andromeda galaxy. The image taken by the Hubble Space Telescope has an amazing 1.5 billion pixels that would require 600 HD television screens to display in full.

This image is too large to display at full resolution and is best viewed here, using the zoom tool.

Andromeda Galaxy, otherwise known as Messier 31, is a large spiral galaxy that lies "just" 2.5 million light years from Earth. Hubble's detailed view captures more than 100 million stars and thousands of star clusters embedded in a section of the galaxy’s pancake-shaped disc stretching across over 40,000 light-years.

The whole galaxy contains over one thousand billion stars.
