Life May be Present on Saturn's Enceladus
	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 sustain life. For example, on Earth, microbes may be found several kilometers underground, living without the need for oxygen or l ... [read more >>]

Robots, the Spearhead of Space Exploration
	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 and very expensive, that’s why we prefer sending robots instead. And frankly, sending a manned mission to Mars won't make ... [read more >>]

Humans May Be Half-Aliens
	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 for researchers are the organic molecules known to us as amino acids, because amino acids are the building blocks of proteins ...

New Organic Molecule Found in Space
	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 interstellar amino acids, which is extremely important while considering that amino acids are the building blocks of proteins, th ...

Arecibo Finds Organic Molecules in Distant Galaxy
	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, which determined a massive star formation process. Observations have shown that the Arp 220 galaxy has a col ... [read more >>]

Life Could be Present all Over the Universe
	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 system formed, providing the organic material for life to appear on Earth. Similar molecules have been detected through the M ... [read more >>]
