The Red Planet
The deeper we look into space, the more places we come across that seem like maybe, just maybe, could host life. From our neighboring planets to distant galaxies sending out weird signals, the list of spots in space worth checking out just continues to grow.
The closest world we should check for signs of life is one we’ve already been to, or at least our robots have. There’s increasing evidence that Mars was once a lot more like Earth, with oceans on its surface. Today it’s more harsh, but it’s not out of the question that we could find some sort of microbes in Martian soil.

Dwarf planet Ceres in the asteroid belt is full of surprises. It started with those big bright spots that turned out to be salt deposits, and there’s also a huge, strange pyramid-shaped mountain, plenty of water beneath the surface and even the building blocks of life. Some people already believe this huge rock is actually an alien ship. The evidence isn’t there to support that theory, but the place does seem worth a closer look.
