伽利略为什么和教会发生冲突？
Why did Galileo clash with the Church?
他公开支持日心说，与当时教会的宇宙观相悖，结果被审判并被迫放弃观点，成为科学自由的著名事件。
He publicly supported heliocentrism against Church doctrine, was tried and forced to recant—a famous case for scientific freedom.

伽利略发现木星卫星为什么很重要？
Why was Galileo's discovery of Jupiter's moons important?
1610 年伽利略用望远镜看到四颗卫星绕着木星转，其意义不在「多了几颗卫星」，而是当场给出了一个不以地球为中心的引力系统的实物样本: 有四颗天体明显不绕地球，地心说的「一切天体都绕地球」就被证伪了。这也回答了当时反对日心说的最强物理质疑——「如果地球在动，月亮为什么没被甩下？」: 木星带着卫星一起跑，说明被拖着的系统可以正常运作。同一批观察还显示卫星位置随时间规律变化，为后来开普勒第三定律在天文尺度上的成立提供了证据，也是牛顿用同一套引力定律统一天地的一次检验。
What Galileo saw in 1610 - four bodies orbiting Jupiter - mattered not for the extra moons but because it put a real non-geocentric gravitational system on the table: four objects demonstrably did not orbit Earth, which falsified the claim that everything does. It also answered the strongest physical objection to heliocentrism, 'if Earth moves, why is the Moon not left behind?': Jupiter plainly drags its moons along, so a carried system works fine. The regular motion of those moons later gave evidence that Kepler's third law holds at scales beyond Earth, and gave Newton a second arena for one law of gravity.

是谁第一次用望远镜认真看星星的？
Who first used a telescope to study the sky seriously?
伽利略在17世纪初把望远镜指向天空，发现了木星的四颗大卫星和月面上的环形山。
In the early 1600s Galileo turned a telescope skyward, discovering Jupiter's four big moons and lunar craters.
