Astronomers Detect Sugar Molecule in Interstellar Space Linked to Raspberries and the Origins of Life

天文学家在星际空间中探测到与覆盆子及生命起源有关的糖分子

A team of astronomers has identified a remarkable organic compound drifting through the vast expanses between stars, a discovery that could reshape our understanding of space chemistry.

一个天文学家团队在恒星之间辽阔的空间中，发现了一种漂浮着的奇特有机化合物，这一发现可能会重塑我们对太空化学的理解。

The sugar, known as erythrulose, was detected within the interstellar medium — sparse clouds of gas and dust scattered throughout the galaxy.

这种被称为赤鲜酮糖的糖，是在星际介质——即散布在整个星系中稀疏的气体和尘埃云——之中被探测到的。

Notably, this same compound occurs naturally in raspberries and is commonly used in commercial self-tanning products.

值得注意的是，这种相同的化合物天然存在于覆盆子中，且常用于商业仿晒产品中。

Researchers employed two dish-shaped radio telescopes located in Spain to gather spectral data from a massive gas cloud near the Milky Way's centre.

研究人员利用位于西班牙的两台碟形电波望远镜，从银河系中心附近的一个巨大气体云中收集光谱数据。

By comparing the telescope signals with laboratory samples, they confirmed the presence of erythrulose in gaseous form.

通过将望远镜信号与实验室样本进行比对，他们证实了气态赤鲜酮糖的存在。

The findings, published in the journal Nature Astronomy, represent the latest type of sugar ever identified beyond Earth.

这些发表在《自然天文学》期刊上的研究结果，代表了在地球之外所发现最新型态的糖类。

Were it not for the broader significance of sugars in biology, such a discovery might seem merely whimsical.

若非糖类在生物学中具有更广泛的意义，这样的发现可能显得仅是奇思妙想。

However, scientists have emphasised that different sugar varieties fuel cellular processes and even constitute components of DNA.

然而，科学家强调，不同的糖类能为细胞运作提供能量，甚至构成去氧核糖核酸（DNA）的组成部分。

Understanding how these organic compounds form in interstellar environments is therefore crucial to unravelling the chemical prerequisites for life itself.

因此，理解这些有机化合物在星际环境中如何形成，对于解开生命本身的化学先决条件至关重要。

This detection is by no means the first instance of intriguing space chemistry.

这次的发现绝非迷人太空化学的第一个案例。

Approximately twenty-five years ago, scientists spotted a molecular cousin of table sugar near the galactic centre.

大约二十五年前，科学家在银河系中心附近发现了食用糖的分子亲戚。

More recently, NASA's OSIRIS-REx spacecraft retrieved black grains from asteroid Bennu that yielded additional sugars alongside a peculiar gum-like substance.

较近期的情况是，美国国家航空航天局的欧西里斯-雷克斯太空船从小行星贝努采集了黑色颗粒，这些颗粒产生了额外的糖分以及一种奇特的黏胶状物质。

#14

Researchers have argued that these extraterrestrial sugar samples lend credibility to hypotheses about how the earliest forms of life on Earth may have sustained themselves.

研究人员认为，这些地球外的糖分样本，为地球上最早期的生命形式如何维持自身生存的假说增添了可信度。

#15

The region where erythrulose was found has also been traversed by NASA's twin Voyager probes, the farthest spacecraft ever launched from Earth.

发现赤鲜酮糖的区域，也曾被美国国家航空航天局的双子航海家探测器穿越过，这两艘探测器是从地球发射过最遥远的太空船。

#16

That such a familiar organic compound should be floating freely through the cosmos strikes many researchers as both humbling and profoundly exciting.

这样一个如此熟悉的有机化合物竟然在宇宙中自由漂浮，这让许多研究人员感到既谦卑又无比兴奋。

#17

Should subsequent observations confirm similar sugars in other galactic regions, the implications for astrobiology would be far-reaching indeed.

若随后的观测证实其他星系区域存在类似的糖类，这对天体生物学的启示确实将会影响深远。
