After the discovery of liquid water on the surface of Mars, speculation has emerged about life on other planets. With liquid water essential for supporting life, here are four other planet and moons that could prove interesting in the future:

In September Nasa made the discovery of liquid markings on the surface of Mars.

The dark markings, named “recurring slope lineae” or RSL, bring the red planet one step closer to harbouring possible life.

Professor Alfred McEwen said: "The possibility of life in the interior of Mars has always been very high.

"It's very likely I think that there is life somewhere in the crust of Mars, microbes."

Nasa also confirmed that they will "send humans to Mars in the near future."

Earth 2.0(02 of04)

It may not be Earth’s exact twin, but it’s a pretty close cousin.

In July researchers discovered the most similar planet yet to earth, 1400 light years away. A world called Kepler-452b.

It's 60% bigger than our own and orbits a sunlike star at about the same distance as we do.

It could have right temperature to allow liquid water to exist on the surface.

Pluto was first discovered in 1930, by Clyde W. Tombaugh, an assistant at the Lowell Observatory in Flagstaff, Arizona.

In September 2015, Nasa released new photographs of the dwarf planet, which showed an incredible resemblance to Earth.

The images were taken during New Horizon’s mission, which was part of a six month fly by of Pluto.

Craters, cliff formations and polar caps all make Pluto comparable to Earth.

Scientists have also discovered nitrogen escaping from Pluto’s atmosphere, all of which makes it a little closer home.

Titan was discovered way back in 1655, by mathematician Christiaan Huygens.

When he looked through his telescope he was surprised to see that Saturn had a moon.

Titan has been compared to Earth in many ways. It possesses a layered atmosphere just like our planet.

It also has a rocky surface, lakes and rivers and data released in June showed that it also shares a peculiar effect that draws gases out of the atmosphere and into space.
