Hubble's greatest hits
Posted April 2, 2009
The Telegraph of London has put together a nice slideshow of the Hubble Space Telescope's coolest pictures. Can you believe Hubble is almost 20 years old?
On the 8 a.m. news, I mentioned that NASA touches up the pictures from Hubble, adding those brilliant colors. A viewer sent me a note, saying it's not just to make the images look nice. The colors represent different elements in the object. For instance, he says, red denotes iron.
