Technology is playing a key role in space research. Is there life beyond Earth? That is something that, for now, is unknown. Although it is in the process of finding out.

If so, it is very difficult to determine what type of organism would be found. What is clear is that everything Hollywood has taught us through its multiple blockbusters it is nothing but science fiction. This is why it is so difficult to imagine what the rest of the universe inhabits.

Today, there are numerous missions that aim to analyze our environment, although somewhat limited by current means. It is true that the main objectives are, right now, on Mars, the Moon or Venus, but there are as many as kilometers away.

Some of those that we already have registered and that could harbor life are the following ten. The classification elaborated by 20 bits raises various options already localized by human beings.


Thousands of years ago, the red planet housed large lakes of liquid water on its surface. This data suggests that, at that time, some form of life could exist. In fact, that’s the goal of the Perseverance rover: to find remains of ancient life. If so, organisms may still exist underground.



It is the moon of Jupiter and, in it, clay mineral deposits associated with organic materials have been located. In addition, experts believe that the radiation that hits its icy surface could be treated as oxygen.


Saturn’s largest moon is home to lakes, rivers, and seas of methane and other hydrocarbons. Likewise, it has enormous sources of organic material, which suggests that it has important and sufficient elements for life.


It is the sixth largest moon of Saturn, where a global salty ocean has already been found. Mind you, completely frozen. Nevertheless, NASA detected hydrothermal activity deep underground, which could provide the necessary heat source for life.


It is, possibly, one of the places that has the best chance of harboring life. In 2020, researchers detected phosphine in its atmosphere, a gas produced naturally by life in oxygen-poor ecosystems.


The largest moon in the Solar System is located on Jupiter and hides an ocean of salt water in its subsoil. In addition, it has a very thin oxygen atmosphere, as well as a magnetic field that protects it from solar radiation.


Share some characteristics of Ganymede: underground ocean and thin layer of oxygen. However, it has a very unfavorable fact: the cold. Being so extreme, everything seems to indicate that it will not be possible to find life in it. At least, as we know it.

IoIn this true-color image of Io obtained by NASA's Galileo probe, we can appreciate its spectacular palette of yellows, oranges and browns. Most of these colors are due to sulfur compounds and elemental sulfur expelled by the hundreds of volcanoes that are currently active on Io.

Io is a moon of Jupiter, the third largest and the one with the highest density. It houses 400 volcanoes that are activated, mainly, by the warming of their tides. Life in it is unlikely, although it could exist in certain areas.


It is the smallest dwarf planet in the solar system. It is located between Mars and Venus and, according to the latest research, could host liquid water 40 kilometers below the surface.


The surface of Neptune’s largest moon is made up of icy water. A fact that already makes us see that it is a very cold place for life. In any case, there is evidence of certain heat currents that could warm its waters and welcome it.
