Deep impact: Sifting through the debris

Article Abstract:

Deep Impact took pictures of the Temple 1 landscape beneath a comet's surface that reveal a complex geological history, sculpted by outgassing, melting and natural impacts. Cross-sections that are 20 to 30 metres high display several different layers, confirming that Tempel 1 would have spent time in different orbits.

The conclusion released by the United Nations and the governments of Ukraine, Belarus and Russia in September 2005 was that no more than 4,000 people are likely to die as a result of Chernobyl.
