extraterrestrial life

A mysterious signal sparked the hopes of scientists and hobbyists. Where did it come from? We reveal the secret.

A computer simulation suggests that life forms could have evolved on Saturn's largest satellite that would not need water to thrive.

Using computer simulations, scientists have concluded that Kepler-62f, 1,200 light-years from Earth, meets the requirements.

An experiment shows that radiation raises an essential component for life in the ice of comets.

Mars is a planet of extraordinary geological and astrobiological interest and the next destination for humanity on its migration into space.

In the Milky Way alone there could be hundreds of billions of planets similar to Earth, capable of supporting life. That is what emerges from the calculations made by a team of planetary scientists from the Australian National University from data obtained on the more than a thousand ex-worlds that have been discovered by NASA's Kepler space telescope.

For the first time in history, a team from NASA's Mars Science Laboratory (MSL) mission has confirmed that there are unequivocally organic compounds in the soil of the planet Mars. This discovery and all its details will be published in January 2015 in the Journal of Geophysical Researh.

In one of the deepest underwater hydrothermal springs in the world in the Caribbean, west of Cuba at about 2,300 meters depth, a large number of small shrimp (Rimicaris hybisae) appear piled on top of each other, creating authentic layers in the chimneys of rock that emanate hot water. This mysterious ecosystem could house the keys to the discovery of extraterrestrial life.
