Reading 1A A MYSTERIOUS VISITOR In October 2017, astronomers in Hawaii saw something surprising. A strange object was moving through the solar system. They had seen many asteroids before, but this was something different. It was long and thin—like a cucumber. The object's speed and direction also showed something surprising. This was an interstellar object—the first ever seen. The object was named 'Oumuamua—Hawaiian for "visitor from afar." Nobody is sure exactly what it is. The simplest idea is that 'Oumuamua is a strangely shaped piece of rock. Perhaps it was knocked out of a far-off star system. However, astronomers saw that its speed increased after passing the sun. Some scientists therefore suggest a different theory. "'Oumuamua could be a piece of alien technology," says Professor Abraham Loeb from Harvard University. Loeb believes this could explain the object's long, thin shape, and also its change in speed. Maybe Oumuamua was a spaceship that came to explore our solar system. "All possibilities should be considered," says loeb. 'Oumuamua can no longer be seen from Earth. But astronomers continue to study the information they got from it. It is still not clear if the object was a large rock, or something else altogether. 'Oumuamua will likely be a mystery for many years to come.

阅读1A 神秘的访客 2017年10月，夏威夷的天文学家看到了一些令人惊讶的事情。 一个奇怪的物体正在太阳系中移动。 他们以前见过许多小行星，但这次不一样。 它又长又瘦，像根黄瓜。 物体的速度和方向也显示出一些令人惊讶的东西。 这是一个星际物体，是有史以来第一个被看到的。 这个物体被命名为“Oumuamua”——夏威夷语，意为“远方的游客” 没有人确切地知道它是什么。 最简单的想法是“Oumuamua是一块形状奇特的岩石。 也许它是从遥远的星系中被淘汰出来的。 然而，天文学家发现，它在经过太阳后速度增加了。 因此，一些科学家提出了不同的理论。 哈佛大学的亚伯拉罕·勒布教授说：“乌穆穆阿可能是一种外星技术。”。 勒布认为，这可以解释该物体细长的形状，以及其速度的变化。 也许Oumuamua是一艘来探索我们太阳系的宇宙飞船。 “应该考虑所有的可能性，”勒布说。 “从地球上已经看不到Oumuamua了。 但天文学家继续研究他们从中获得的信息。 目前尚不清楚该物体是一块大石头，还是其他什么东西。 “Oumuamua在未来很多年都可能是一个谜。

'Oumuamua: What We Know Entered the inner solar system in August 2017. Possibly came from a star system 25 light years from our sun—a 600,000-year journey. Reached a top speed of 315,800 km/h—more than 250 times the speed of sound—as it passed the sun. First seen by astronomers in October 2017 when it was 33,000,000 km from Earth—about 85 times further than our moon 3.

Oumuamua：我们所知道的 2017年8月进入内太阳系。 可能来自距离我们太阳25光年的恒星系统，这是一次60万年的旅程。 当它经过太阳时，最高速度达到了315800公里/小时，是音速的250倍多。 天文学家于2017年10月首次观测到 当它距离地球3300万公里时，大约是我们月球3的85倍。
