While looking for evidence of life on other bodies in the solar system, researchers often evaluate the degree of habitability relying on the presence of water, sunlight, oxygen and so on. However, in the last decades, we came to learn that none of these three basic ingredients is absolutely required in order to susta... |

Why are we so fascinated with the Moon? I mean just look around you, the universe is more than the Earth and its large satellite. Mars, Venus and Mercury are just around the corner, why are we so reluctant at sending a manned mission to any of these planets? The truth is that space missions are extremely dangerous an... |

Primitive organic molecules can be found throughout the whole solar system, but they are mostly present in carbonaceous chondrite meteorites. They can also be found amongst the interplanetary dust particles which formed in the early days of the solar system. However, the materials that have the most scientific value ... |

In more than four decades of space study, astronomers have been able to identify more than 140 different molecular substances in interstellar clouds of matter, but also in accretion disks surrounding young stars. Many of these substances fall into the 'bio'-molecule category of molecules and are mostly inte... |

We know organic molecules are scattered throughout most of the Milky Way, but it was about the time for the astronomers to find some in distant galaxies. Located at about 250 million light years away in the Serpens constellation, the Arp 220 galaxy is actually the result of the collision between two separate galaxies... |

Evidence of the same chemicals that represent the building blocks of life on Earth has been found in nearby galaxies, but to identify the exact identity of these molecules and when they became abundant is no easy task. Scientists think that organic molecules were present in the cloud of gas out of which the solar sys... |
