摘要

For decades, Dr. Oliver Manuel, a professor of nuclear chemistry at the University of Missouri-Rolla, has been telling anyone who will listen that the accepted theory on the Sun's origin—that it was created slowly along with the planets in a huge collapsing cloud of hydrogen and helium—is seriously flawed. "That story about the solar system's creation certainly doesn't match my findings," says Manuel, who, back in the 1970s, uncovered evidence supporting a different theory: that a supernova explosion created the Sun and planets. Lately, it appears that Manuel's ideas aren't quite as far-fetched as they used to seem. New findings at Arizona State University convinced a Chinese-American team of scientists that the origins of the solar system, indeed, were hotter and more violent than previously thought. After detecting clear evidence in meteorites for the past presence of chlo-rine-36, they concluded that a nearby supernova must have injected radioactive isotopes into the interstellar cloud of light elements that was forming our Sun and planets. The conclusions are reported in the Feb. 1, 2005 issue of the Proceedings of the National Academy of Scientists.
