Jupiter could be considered an independent solar system, only in miniature form. The gas giant has the same basic ingredients as the sun and is surrounded by dozens of geologically diverse moons. Overall there are 79 confirmed moons of Jupiter. Out of these, four ancient moons have astronomers really excited because they offer up some of the most distinctive geology in the solar system. Counting pieces of information of deep subsurface oceans that could be home to life. So, let’s start revealing the Secrets of Jupiter’s Moon.

Secrets of Jupiter’s Moon- Galilean Moons’

The Galilean moons are named after Galileo Galilei, who first observed them in 1610. They are the largest moons of Jupiter. The four Galilean moons are

  • Io
  • Europa
  • Ganymede
  • Callisto

Io, Jupiter’s closest Galilean moon, is unusual because its composition is closer in comparison to the terrestrial planets than the icy bodies that surround it. Io is also the most volcanically active body known in the solar system with over 400 active volcanoes. This is because of the inside heating created by the pulling and extending impact of Jupiter’s gravity and other smaller neighboring moons on Io, as it circles Jupiter. That equivalent warming impact is the motivation behind why, a few space experts trust that Jupiter’s second Galilean moon is home to a deep subsurface ocean, up to double the volume of Earth’s oceans.


Europa-Secrets of Jupiter’s Moon

Unlike Io, Europa has an icy surface, but below it, astronomers think there may be a salty ocean that could harbor life-bearing chemistry, including organic molecules. At the point when Europa swings by Jupiter on an elliptical orbit, gravitational tidal powers flex and stretch the sides of the moon, making inward friction that basically heats the moon from inside. Utilizing its Europa Clipper spacecraft during the 2020s, NASA intends to get a closer look at the moon so as to affirm the presence of a potential ocean.


Ganymede-Secrets of Jupiter’s Moon

Europa’s neighbor, Ganymede, is also believed to have an ocean hidden under its thick icy shell. The moon’s magnetic field may be affected by an electrically conducting layer from within, which hints at the existence of a liquid saltwater ocean. But Ganymede’s distance from Jupiter means there’s a weaker tidal force at play, so it’s less likely that liquid water is present. The moon is the only one in the solar system known to have a magnetosphere, protecting its surface from harmful radiation and solar wind. As Jupiter’s largest moon, Ganymede would be considered a planet if it were orbiting the Sun.


Callisto-Secrets of Jupiter’s Moon

Out of all four Galilean moons, Callisto is the farthest from Jupiter. The moon is purported to be one of the most heavily cratered objects in the solar system. With some impact basins expanding to about 2,600 kilometers across, these craters could teach us a lot about the formation of our early solar system, as astronomers believe its surface hasn’t changed in over four billion years.

Unmanned spacecraft have been conducting flybys of the Galilean moons for decades and findings from these missions suggest an even greater presence of water. Alongside NASA’s Europa Clipper, the European Space Agency’s “JUpiter ICy” moons Explorer otherwise known as JUICE will pick up a more profound comprehension of the moons’ strange properties. But getting to these moons will be no small feat since the craft will need to slingshot around the Sun and then travel about 800 million kilometers before being caught by Jupiter’s massive gravitational pull.

If the spacecraft can survive this arduous journey and manage to generate enough energy to travel between the moons, astronomers will gain an unparalleled glimpse into what lies beneath their surfaces, which could even result in the discovery of the first forms of life beyond Earth. Space-crafts take us through the profundities of the universe, clarifying strange cosmic marvels and insane designs for future investigation.

I hope you like these secrets of Jupiter’s moon as all human beings have desires to look up in the sky in search of secrets.
