太阳黑子突然失踪 新冰期提前?专家急了

我们都知道,当我们用科学的方法观察太阳时,会发现它的表面往往存在许多暗点,这些暗点是太阳强磁性活动抑制对流所产生的低温区,它的学名叫太阳黑子。然而最近,俄罗斯的科学家观察发现一个诡异的现象:太阳面朝地球的这一边,居然连一颗黑子都看不到了!

据俄罗斯媒体报道,俄联邦科学院物理学院的天文实验室日前爆出一个惊人消息,由两周前拍摄的太阳另一面转向地球时的照片分析,该角度的太阳无任何太阳黑子,太阳表面光泽剔透,无任何瑕疵,就像刚出生婴孩的肌肤一样。尽管科学家还很难确定现在在太阳的另一面上是否有黑子活动,但这一现象着实令人大开眼界,目前唯一可知的是,这样的太阳外观可与17世纪前给人们展示的相媲美。

 

一直以来,人类对于太阳仍处于知其大略的状态,真正开始科学地系统性研究太阳不过270年时间。通过这段时间的统计研究科学家得知,太阳黑子数是测量太阳11年周期的主要参数,每一轮周期过后,太阳黑子的数量就会达到峰值,在大约到达半个周期时,数量达到最少,太阳磁场就这样一直处于增强与减弱的周期性循环中,也因此观察太阳黑子是评价太阳活动强度的主要方法。

 

然而,即使有以上理论,科学家也难以解释这样光滑无暇的太阳面部,况且这些理论的本质原因也还没有被人们彻底摸透。都说强烈的太阳黑子活动会给地球气候、人类通讯设备带来影响甚至破坏,那么太阳这样的强力祛斑过程又会给地球整出什么样的幺蛾子呢?目前俄罗斯科学家只给出一个冷漠的结论:太阳的活跃性正在逐渐趋于零。至于太阳黑子极少期带来的影响,过去曾有报道其称可能激发地球新冰河时期的到来,但实际上,科学家们还在众说纷纭,迄今为止仍是未解之谜。
