1987年夏,加拿大和美国天文协会在温哥华召开了一次联席会议,天文学家报告了新的观测,认为行星多得难以计数。这是三位加拿大天文学家经过6年认真细致的工作得出的结论,引起了科学家和局外人的强烈兴趣。因为在宇宙中除了围绕太阳旋转的9颗行星之外,是否还有任何行星,人们迄今依然是众说纷纭、毫无把握的。从某些观点上说,人们都会把太阳系外存在绕其它恒星旋转的行星看作是激动人心的发现。首先,在理解恒星怎样诞生方面,它是一个重要的论据;其次,对于地球之外是否存在生命的争论而言,它也是一个至关重要的因素。
In the summer of 1987, the Astronomical Society of Canada and the United States held a joint meeting in Vancouver, where astronomers reported new observations that the planet was overwhelmingly countable. This is the conclusion of three Canadian astronomers after six years of meticulous work that has drawn strong interest from scientists and outsiders. Because there are still no planets apart from the nine planets that revolve around the sun in the universe, people have so far been divided and uncertain. In some ways, people see the planets that exist around the extrasolar rotation around other stars as exciting discoveries. First, it is an important argument in understanding how a star is born; and second, it is also a critically important factor in the debate about whether there is life outside of Earth.
