A video fly-through of a high-definition image of the Andromeda Galaxy helps put the vastness of the universe in perspective. The panorama covers a 61,000-light-year-long span of Andromeda. NASA notes there are more than 100 million stars in the image. "It's like photographing a beach and resolving individual grains of sand," says NASA. It helps that Andromeda is "only 2.5 million light-years away from Earth." That's far away, but not nearly as far as some of the galaxies Hubble is watching, which are billions of light-years from here.
Your reaction to the video will depend on your perspective. It may inspire awe, humility, wonder or even a bit of fear at the vastness of the universe. No matter what, it's an experience worth having.
