"We have discovered a second repeater and its properties are very similar to the first repeater," said Shriharsh Tendulkar of McGill University, Canada.
加拿大麦基尔大学的斯里哈什·滕杜卡尔说:“我们发现了重复的电波,它的属性与上一次发现的电波非常相似。”
"This tells us more about the properties of repeaters as a population."
“这使我们获得了更多关于这些电波整体特性的信息。”
There are a number of theories about what could be causing them.
目前存在多种理论解释这些宇宙电波的来源。
They include a neutron star with a very strong magnetic field that is spinning very rapidly, two neutron stars merging together, and, among a minority of observers, some form of alien spaceship.
例如,这些电波可能来自一颗具有强磁场的快速旋转的中子星,可能是两颗中子星合并在了一起等。此外,有少数观察者认为,这些电波其实是来自某种外星宇宙飞船。
