b. Why is Europa thought to be a good place to look for life?

Answer 1

a) Io is the innermost Galilean moon of the Jupiter planet. It is one of the fourth largest moon out of the four which has largest density and has the least amount of water.

It is most valconic activity of the solar system.

The surface of the lo is sploched with lava lakes and floodplains of liquid place. It is about 4.5 billions years old and it is approximately same as of Jupiter. Lo is tidally locked and so the same side always Jupiter faces. It is slightly larger as compare to the moon of the earth.

B. Because the moon Europa is flowing with a buried liquid water ocean that contains much more oxygen and enough to support life as scientist said. However, there is no solid evidence of life besides earth but Europa has been considered as a good place to look for a biological activity.
