NASA clicks the largest ever picture of our neighbouring galaxy!
NASA captured the sharpest ever image of our galactic next-door neighbour
Can you imagine floating among the stars? Well that’s how this feels like!
NASA captured the sharpest large composite image ever taken of our galactic next-door neighbour, the Andromeda galaxy (M31), using the NASA Hubblespace telescope. Though the galaxy is over 2 million light-years away, 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.

It's like photographing a beach and resolving individual grains of sand. And there are lots of stars in this sweeping view — over 100 million, with some of them in thousands of star clusters seen embedded in the disk.
This ambitious photographic cartography of the Andromeda galaxy represents a new benchmark for precision studies of large spiral galaxies that dominate the universe's population of over 100 billion galaxies.
Never before have astronomers been able to see individual stars inside an external spiral galaxy over such a large contiguous area. Most of the stars in the universe live inside such majestic star cities, and this is the first data that reveal populations of stars in context to their home galaxy.
