The universe
Astronomers and visualization specialists from NASA’s Universe of Learning program have combined visible and infrared vision of the Hubble and Spitzer space telescopes to create an unprecedented, three-dimensional, fly-through view of the picturesque Orion Nebula, a nearby star-forming region.
Watch the video and remember that even in binary (two-star) systems each star is at least 0.5 ly (lightyear, of the distance light can travel in a year – half a ly is just over 4.73 trillion kilometres) apart. Just wonder at the size of our universe in total if this is a relatively small star-making area.
