  1. DNA Building Blocks Found in Meteorites (Time.com)
      "Scientists have been finding evidence of life inside meteorites for well over 100 years — that, or the building blocks of life. The claims of life have been debunked every time, most recently just this past March. It always turns out to be a wishful interpretation of chemicals, minerals and tiny structures inside the meteorite that could be the fossilized husks of long-dead bacteria — but almost certainly aren't."

      "The building blocks, though, have proved a lot more convincing. As far back as the 1960s, it was clear that amino acids, which link up to form proteins, can and do form in space. And now scientists at NASA's Goddard Space Flight Center in Greenbelt, Md., are claiming that another set of molecules crucial to life have also rained down on Earth: adenine and guanine, two of the four so-called nucleobases that, along with cytosine and thymine, form the rungs of DNA's ladder-like structure." 08-11

      "The term meteor comes from the Greek meteoron, meaning phenomenon in the sky. It is used to describe the streak of light produced as matter in the solar system falls into Earth's atmosphere creating temporary incandescence resulting from atmospheric friction." Includes pictures, articles, and links.

  7. Perseids (NASA Science)
      "The Perseids are probably the best-watched of any annual meteor shower. They come in mid-August when it's warm and comfortable to be outside at 4 o'clock in the morning. They are bright, numerous, and dependable."

      "This year the shower peaks on Wednesday, August 13th." 8-03
