NASA has released a 1.5 billion-pixel image of the Andromeda Galaxy (or M31 as NASA scientists call it) which was captured by NASA/ESA Hubble Space Telescope and is actually made up of 411 images. To look at the whole image, one needs to have a 600 HD television screen. It shows over 100 million stars, also travels more than 40,000 light years.
It is the largest and sharpest image ever taken of the galaxy which requires 4.3 GB of disc space. Andromeda is nearest galactic neighbour which is over 2 million light-years away from earth, according to The Hubble Space Telescope that is a project of international cooperation between NASA and the European Space Agency.
This is one part of one galaxy among the 100 billion galaxies contained in the universe and, “The Hubble Space Telescope is powerful enough to resolve individual stars in a 61,000-light-year-long stretch of the galaxy’s pancake-shaped disk,” NASA wrote in a Blog Post.
