NASA shows largest image ever of Andromeda Galaxy
NASA released the largest picture ever taken earlier this month, with a staggering 1.5 billion pixels, of the Andromeda Galaxy.
To get an idea of how massive the picture is, you'll need a 600 HD television screens to look at the whole image.
On Jan. 5, NASA released the image of our closest galactic neighbor.
This YouTube fly-through video shows the detail of the picture captured by NASA's Hubble Space Telescope. To date, the video has over 2.9 million page views.
The full image takes you through 100 million stars and travels more than 40,000 light-years. Each of those white dots is a sun, much like the sun that powers all life on Earth.
This is just one galaxy. There are well over 100 billion more of them out there. Still think we're alone?
