Underwater caves may hold the answer to one of the most important questions in the world – how did life evolve? A particular set of such caves, located in the Bahamas, may be especially suited to answer this question, investigators explain.
In addition to revealing the intricate history our planet has, invest... |

Studies published thus far have provided sufficient arguments that life as we know it would have the highest chances of emerging on planets located in their star's habitable zones. These are areas around each star where temperatures are right to support liquid water. A new study now shows that chemistry also pla... |

A new photograph of Ligeia Mare depicts the landscape feature in beautiful colors that remind us of Earth. Yet, the sea is located on Titan, Saturn's largest moon, and is filled with liquid hydrocarbons such as methane and ethane, rather than water.
Even so, Titan and Earth are not that different. Granted, atm... |

Since the beginning of our efforts to discover alien life on other worlds, a lot of the effort has been focused on discovering exoplanets orbiting in the habitable zones of their stars. But what awaits discovery if we look in the habitable zone of methane? What astronomers are focused on is planets in an area where ... |

A team of astronomers from the Brown University, in Providence, Rhodes Island, says that the current interpretation of geological data collected from Mars may be wrong. The experts propose that the vast majority of water that once flowed on the surface of the Red Planet can still be found underground.

Astrophysicists believe that extrasolar planets located in regions dense in dark matter could represent the last bastion life can occupy as the Universe grows old. Scientists say that these objects remain warm even if they are not accompanied by a parent star. Dark matter alone is enough to heat them. Therefore, tril... |

One of the things that made astrobiologists so interested in Saturn's largest moon is the fact that it shares many similarities to our own planet, in terms of atmospheres, atmospheric chemical cycles and so on. However, how Titan got to its current configuration is still a matter of debate. At this point, scient... |

The fact that life exists in the Milky Way is plain as day. Now the thorniest issue is establishing how to find it. Astronomers say that limiting our search for our origins to this planet, the solar system or whatever exoplanets we can see exclusively would be a mistake.
They argue that there are two primary ways... |

Undoubtedly, the day when the NASA Viking 1 spacecraft landed on the surface of Mars remains one of our species' most glorious moments. But this flight is also one that may have put us back by a few decades in terms of understanding the origins of life. The main goal the lander had was to figure out whether Mart... |

Though many experts argue that carbon-based lifeforms are the most like to continue evolving, others believe that there are chemicals beside carbon that can underly life. Silicon is a good example for it, but other chemicals may be capable of this as well. Famed physicist Stephen Hawking is one of the experts who arg... |

Ever since the discovery of the first exoplanet, some two decades ago, astronomers have said that the emergence of life can be accompanied only by very strict conditions. Today, some experts suggest that this may in fact be a natural phenomenon on habitable extrasolar planets.

A new twist in an established theory argues that all life on Earth may have developed from the remains of dead alien viruses, that arrived here on comets and other space impactors.
