According to scientific research, it may exist. On June 5438+065438+ 10, 2009, scientists from the University of Arizona in the United States, such as Richard green Berg, discovered that Europa might have life similar to fish. Now many scientists believe that Europa has no land on its surface, but there is an ocean covering the whole world under the thick ice, with a depth of about 160 km.

Greenberg's latest research shows that Europa's ocean is absorbing a lot of oxygen, which is much more than the previous simulation results.

Scientists believe that this kind of oxygen is enough to support the existence of various life forms. In theory, Europa's ocean should contain at least 3 million tons of fish. Greenberg explained, "Although we can't say that there is definitely life there at present, we at least know that the physical environment there supports the existence of life."

Extended data

The main composition of Europa is similar to that of terrestrial planets, that is, it is mainly composed of silicate rocks. Its surface is covered with water, which is estimated to be hundreds of kilometers thick (the upper layer is a frozen ice shell and the lower layer is a liquid ocean).

The magnetic field data collected by Galileo spacecraft during its orbit around Jupiter from 1995 to 2003 show that Europa can generate its own induced magnetic field under the influence of Jupiter's magnetic field. This discovery suggests that there may be a conductive layer similar to the salt water ocean on its surface, and Europa may also have a metal iron core.
