Earlier this month, NASA and ESA released the biggest and highest resolution image of our galactic neighbor, Andromeda, that has ever been taken. The 1.5 billion pixel image was taken by the Hubble Space Telescope. Each tiny dot of light in the picture represents one of 1 trillion stars in the galaxy; many with their own expansive planetary systems.
As you watch this video and think about Andromeda’s size, remember that this is just a small part compared to the rest of the universe. As large as this galaxy is, it is only one out of 200 billion galaxies in the known universe.
