Over 100 years ago‚ if you asked a scientist about the universe they would say it’s eternal‚ infinite and stable. No beginning and no end.

Here he described that the surface of the moon is rough rather than smooth‚ proved the existence of many more distant stars than were currently known‚ and went into detail about how he saw the planets through his telescope that appeared as circular globes. Also in his book‚ Galileo wrote about the moons of Jupiter and Venus’s phases like those of the moon‚ and the dark spots on the sun. A few years later in his career‚ Galileo began to have some conflicts with the

largest moons in the Solar System. Europa was discovered in 1610 by Galileo Galilei[1]and possibly independently by Simon Marius around the same time. Progressively more in-depth observation of Europa has occurred over the centuries by Earth-bound telescopes‚ and by space probe flybys starting in the 1970s. Slightly smaller than Earth’s Moon‚ Europa is primarily made of silicate rock and probably has an iron core. It has a tenuous atmosphere composed primarily ofoxygen. Its surface is composed of water
