Numerous probes on the Martian surface have so far failed to provide any evidence of such life. What we do find are unweathered craters where meteors have hit in past ages, extinct volcanoes fifteen miles high, and dry river beds. Which suggests that in ages past Mars may have had water, or some kind of liquid, on its surface. Next out is Jupiter, the largest of the planets, larger than all the other planets put together. Jupiter is probably not solid anywhere.
Most astronomers now believe it is made of mostly hydrogen, liquid inside and gas on the surface.
Dappled on the surface is a gigantic red spot thirty thousand miles long by six thousand miles broad, a surface area larger than our earth. This red spot, we know, is a great whirling storm, though why it should persist so long, we don't yet know. Jupiter was the first of the planets besides Earth shown to have moons. Galileo found the first four back in 1610 when he trained his newly made telescope on the giant planet. Today we know that Jupiter has at least 14 moons.
