For many years, Jupiter trailed behind Saturn for the record number of moons. We hope you liked this trip to the Galilean Moons. Four centuries later, we know that those points of light seen fluttering in the eyepiece of Galileo’s telescope were, in fact, the moons Io, Europa, Ganymede, and Callisto the four largest of Jupiter’s extended family of moons. It provided strong evidence to the Copernican theory and was the foundation of heliocentric model of the Solar System They are the first discovered natural satellites besides our Moon. The discovery of the Galilean Moons opened so many doors and ideas for scientists. ![]() Nevertheless, more studies and research is needed to be done to be certain. This gives enough possibility for scientists to think that it may harbor life. Europa’s surface is covered with an ice shell and is believed to have liquid water beneath. Lastly, we venture on the most promising Galilean Moon to look for life. This means that there were no signs of tectonic plate movements or volcanic activity on this moon. While the previous moon, Io, is very geologically active, Callisto, on the other hand, is said to be geologically dead. Containing over 400 active volcanoes, its surface is always changing as these volcanoes erupt continuously.Ĭallisto is often described as a hunk of ice and rock. This moon of Jupiter is the most volcanically active spot in the Solar System. This ocean is believed to have more water than what we have here on EarthĪmong the Galilean moons, Io is said to be the first moon to be observed by Galileo. A few years ago, the Hubble Space Telescope found evidence that Ganymede contained saltwater oceans beneath its surface. Named after the cupbearer for the Greek gods, Ganymede is the largest natural satellite in the Solar System. The four moons Io, Callisto, Europa and Ganymede that Galileo saw then, became known as the Galilean Moons that we can still observe to this day. This event was the foundation for the invention of the telescope for astronomical use. ![]() He discovered it when Galileo pointed the telescope lens made by Optometrist Hans Lippershey. The Galilean Moons were first observed by Galileo Galilei in 1610. ![]() In this article, we will discuss the most famous moons of Jupiter The Galilean Moons. Among these storms is the Great Red Spot which is the largest anticyclonic storm in the Solar System.Īs interesting as its features, Jupiter is also home to many natural satellites. Its atmosphere composed mainly of Hydrogen and Helium are always hurled up in storms. The planet is also famous for its weather systems. For comparison, Jupiter can easily fit more than 1,300 Earths in it. think Oklahomans want to use their tax dollars to indoctrinate kids'. Jupiter is the largest planet in the Solar System. Astronomers discover deep red auroras on Jupiter's Galilean moons. ![]()
