THE ANDROMEDA galaxy (or M31 as NASA scientists call it) is 2.5 million light-years away and contains one trillion stars, but these figures did not prevent NASA Hubble Space Telescope to capture a section of it in the largest composite image ever taken.
The 1.5 billion pixel picture is actually made of 411 images (taken over 3 years) that sweep over 100 millions stars and manage to focus on individual ones in the same way as one would focus on one grain of sand when taking a picture of a beach, NASA explains. Yes, that’s one powerful telescope.
If you don’t feel ridiculously small after watching this, remember that this is one part of one galaxy among the 100 billion galaxies contained in the universe. That should do it.
