NASA and ESA released the largest image of our galactic neighbor, Andromeda that has ever been taken.
Andromeda galaxy is the closest galaxy to us. The image was taken by the Hubble Space Telescope. They took 411 images and put them together to create the largest image ever taken. It’s a whopping 1.5 billion pixels and requires about 4.3 GB of disk space!
Each tiny dot of light in the picture represents one of 1 trillion stars in the galaxy; many with their own expansive planetary systems. The image will blow your mind.
As you watch this video and contemplate Andromeda’s mind-boggling size, remember that this is just a drop in the bucket 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.
Now, sit back, watch and enjoy having your mind blown.
Facts about the largest image to keep in mind:
1. Each tiny dot in the image is a star, that could have its own solar system. Don’t bother counting. There are an estimated 100 million stars in this image alone.
2. The Andromeda galaxy is about 2.5 million light-years from Earth, which means it takes light 2.5 million years to span the distance. Compare that to light from the sun, which takes only 8 minutes and 17 seconds to make the trip to Earth.
3. Scientists estimate the Milky Way and Andromeda are two of the universe’s 200 billion galaxies.
4. The Hubble Space Telescope is powerful enough to show individual stars in this 61,000-light-year-long stretch of the galaxy. NASA scientists compared it to photographing a beach and showing individual grains of sand.
For a second, take a moment and think of how big our universe is. Where are we? Where do things begin? And where does it stop? We don’t have to answer this literally, but simply picture it in your mind. What you are about to see in this video will likely rock whatever you just imagined in your mind.
