Some people theorize that there could be life on Mars. The idea came from the fact that Mars and Earth are similar. However Mars' core cooled long ago which means it has no magnetic field which means that its atmosphere is being striped away and surface is bombarded with harmfull radiation from the sun so the prospect of current life is not as good adult could be. Another place is Jupiter's moon Europa. There is evidence indicating that there is a liquid ocean order the icy surface of the moon which which would explain the cracks we see on the surface. Many scientists beleive that this ocean under the surface could harbor life. I hope this helps. Let me know if anything is unclear
