If the presence of active volcanoes is confirmed, scientists speculate that the planet might become a perfect destination for those wishing to learn how "interiors of planets" operate.

科学家们推测,活火山的存在已经得到了证实,对于那些希望了解“行星内部”是如何运作的人来说,这颗行星可能成为一个完美观测对象。

While some scientists who struggle to uncover the mysteries of Venus focus their attention on the planet's weather, hoping to discover possible signs of life, others delve into the secrets of the inhospitable world's depths.

当一些科学家努力揭开金星的秘密时,他们把注意力集中在这颗行星的气候上,希望发现可能存在生命的迹象,而另一些科学家则钻研这个不适宜居住的世界深处的秘密。

According to Universe Today, a team led by researchers from the Lunar and Planetary Institute (LPI) now postulate that Venus may still harbor active volcanoes, which would make it the only such planet in our solar system to do so (beside Earth, of course).

据《今日宇宙》报道,由月球与行星研究所(LPI)的研究人员领导的一个小组现在假设,金星可能仍然有活火山,这将使它成为太阳系中唯一个有活火山的行星(除地球之外)。

While traces of volcanic activity were discovered on Venus back in the 1990s by NASA's Magellan spacecraft, as the media outlet points out, the scientists, who examined how the planet's lava flows would react to its atmosphere, were able to determine that "the lava flows observed on Venus were very young", thus leading the team to conclude that there should still be active volcanoes there.

尽管美国宇航局的麦哲伦号宇宙飞船在20世纪90年代在金星上发现了火山活动的痕迹,但正如媒体所指出的那样,研究火星熔岩流对大气的反应的科学家们能够确定“在金星上观察到的熔岩流非常年轻”,从而使研究小组得出结论,那里应该仍然有活火山。

Commenting on their findings which were published in Science Advances, study lead Justin Filiberto, staff scientist with the LPI, remarked that if the presence of volcanic activity on Venus is confirmed, the planet might become "a great place to visit to better understand the interiors of planets".

研究负责人、LPI的科学家贾斯汀·菲利贝托(Justin Filiberto)对他们发表在《科学进展》(Science Advances)杂志上的发现发表评论称,如果金星上的火山活动得到证实,这颗行星可能会成为“一个更好地了解行星内部结构的好地方”。

"For example, we could study how planets cool and why the Earth and Venus have active volcanism, but Mars does not", he explained. "Future missions should be able to see these flows and changes in the surface and provide concrete evidence of its activity".

他解释说:“例如,我们可以研究行星如何冷却,为什么地球和金星会有活火山活动,而火星没有。”“未来的特派团应能看到地表的这些流动和变化,并为其活动提供具体的证据”。

Last year, the team also announced that Venus could never have hosted life as the planet was overflowing with lava rather than being covered in oceans in the past.

去年,研究小组还宣布,金星上不可能存在生命,因为在过去,金星上的熔岩泛滥,而不是被海洋覆盖。
