Also included in the top ten science stories of 2009 are the NASA LCROSS spacecraft that found water on the Moon, the National Ignition Facility, and money to stimulate science.
Page two concludes with the SciAm website featuring the Top 10 Science Stories of 2009.
For instance, one of the top 10 stories in science within the year 2009 is from the Lawrence Livermore National Laboratory in the United States.
The NIF is now the world’s largest laser system.
The Scientific American article The Top 10 Science Stories of 2009 states, “The main mission of the NIF is to generate technical data necessary to maintain the U.S. nuclear arsenal without the actual detonation of nuclear warheads."
But NIF designers also think that astrophysics studies will benefit because the system creates conditions similar to those in supernovae, black hole event horizons and the centers of gas-giant planets.”
The Scientific American article also mentions other science highlights in 2009: “The year also celebrated several important past events: It saw the bicentennial of Charles Darwin's birth and the 150th anniversary of the publication of his Origin of Species; the 40th anniversary of the first humans on another world; and the 400th of Galileo's report that proved not all heavenly bodies circle the Earth."
"The year also marked the first occasion in which the science Nobel Prize committee honored more than one woman—four, in fact.”
