Scientists have found new evidence of volcanoes erupting on Venus, a planet near Earth. They used old radar data from NASA’s Magellan spacecraft, which flew around Venus from 1990 to 1992. Radar can see through the thick clouds on Venus and show the planet’s surface.

The scientists studied two volcanoes called Sif Mons and Niobe Planitia. They found that lava erupted and made new rock between 1990 and 1992. The lava flows were very big. One eruption made enough rock to fill 36,000 Olympic swimming pools. The other made even more rock, enough to fill 54,000 pools.

This discovery shows that Venus is more active than we thought. Scientists want to learn how volcanoes change Venus and why it is different from Earth. NASA plans a new mission called VERITAS. It will use better radar to make 3D maps and study volcanoes on Venus in detail.

Studying active volcanoes helps scientists understand how planets change over time. The new data from Magellan adds important knowledge about Venus’ history and its surface today.

难句解析

  1. 1

    They used old radar data from NASA’s Magellan spacecraft, which flew around Venus from 1990 to 1992.

    句中“which flew around Venus from 1990 to 1992”是定语从句，修饰前面的“Magellan spacecraft”，不是修饰“data”。意思是：他们用的是麦哲伦号探测器（1990到1992年绕金星飞行）的旧雷达数据。

  2. 2

    One eruption made enough rock to fill 36,000 Olympic swimming pools.

    “enough rock to fill 36,000 Olympic swimming pools”是“足够填满3.6万个奥运泳池的岩石”，不是说填泳池，而是用泳池做比喻。意思是：一次喷发产生的岩石量非常巨大。

  3. 3

    Studying active volcanoes helps scientists understand how planets change over time.

    “helps scientists understand how...”结构，help 后直接跟动词原形，意思是“帮助科学家了解……”。整句：研究活火山有助于科学家了解行星是如何随时间变化的。
