  1. A billowing tower of gas and dust rises from the stellar nursery known as the Eagle Nebula. This small piece of the Eagle Nebula is 57 trillion miles long (91.7 trillion km)

  2. Optics

  3. The Crab Nebula is a supernova remnant, all that remains of a tremendous stellar explosion. Observers in China and Japan recorded the supernova nearly 1,000 years ago, in 1054

  4. Intricate structures of concentric gas shells, jets of high-speed gas and shock-induced knots of gas make up this complicated planetary nebula. The Cat's Eye Nebula is about 1,000 years old, and could have resulted from a double-star system

  5. Hubble Space Telescope

  6. And from the very large…

  7. H1N1 Influenza virus (approx 100nm)

  8. 4.1 Producing Light Light is emitted from matter by electrons that have absorbed energy to become ‘excited’, then the electrons release back some of the extra energy as light.
