By peering throughout the universe with various telescopes, astronomers have found water in many places, such as large gaseous planets the size of Jupiter. But, up until now, they haven’t found water on smaller planets, or any approaching the size of our own.
宇航员通过各种天文望远镜观察星球,已经在很多地方发现了水源,例如水星,它跟木星的体积相近。但是直到现在,他们还没发现在一些跟地球体积一样的星球上发现水源。
In a study published in the journal Nature, scientists say they detected a “crystal clear” fingerprint of water vapor coming from a planet dubbed HAT-P-11b, nearly 729 trillion miles miles away.
在自然杂志发表的一项研究中,科学家说他们在一个星球上发现了清晰的水蒸气的痕迹,这个被称为HAT-P-11b的星球,在地球万亿英里之外。
The planet has a mass about 26 times that of Earth, and is about the same size as Neptune. Researchers detected the presence of water by measuring the wavelength of light emitted from HAT-P-11b’s atmosphere; water absorbs a specific subset of radiation, which leaves a specific “signature” in the light that passes through it.
这个星球质量大约是地球的26倍,体积跟海王星差不多,观测者通过测量从 HAT-P-11b的大气层发射出来的光的波长发现了水的存在。水会吸收辐射中的一种特殊光波组,最后留下一种特殊的波长,它作为识别标志通过。

“From the strength of the absorption, the authors conclude that the planet’s atmosphere has a composition not dissimilar to those of the giant planets of our solar system—mostly hydrogen, with trace amounts of heavier atoms, including oxygen in the form of water vapour,” writes astronomer Eliza Kempton, in a Nature commentary accompanying the research.
从吸收波的强度中,作者总结到地球中的大气圈和太阳系其他巨型行星的组成是相似的,大部分是包含重原子的氢,包括水蒸气中的氧原子。在一个自然评论研究的天文学家 Eliza Kempton写到。
The results are interesting because water is a precondition for life, but its presence doesn’t ensure that life would be found there, the authors write.
作者写道,这个研究非常有趣,因为水是生命存在的前提条件,但是在这个星球的表面不一定有生命存在。
The researchers, from the University of Maryland and elsewhere, made the observations and measurements using the Hubble Space Telescope.
