In 1992 the first exoplanets were discovered, that is, the first planets detected outside the solar system. How are they? Do they look like those here? Now, eleven years later, enough data have been collected to measure its mass, according to astronomers the mass of the Earth is approximately the same.

In addition, they discover that these planets revolve around a pulsar, which is not good news for astrobiologists. This means that these planets are receiving radiation constantly and in these conditions it is impossible to develop the life we know.
