The list of conditions that need to be met for a planet to be considered habitable is now one item larger. Experts say that even exoplanets located in their stars' habitability zones may not be inhabitable if their axis have extreme tilts, such as Uranus'.
On Earth, a tilt of 23+ degrees, achieved more tha... |

According to a paper published in a recent issue of the scientific journal Solar System Research, a Russian expert was recently able to discover what appears to be Venusian lifeforms, in old pictures.
Back in the 1970s and 1980s, the Soviet Union dispatched a series of space probes to our neighboring planet, includi... |

The fact that the Earth has a tilted axis when compared to that of the Sun does wonders for our planet, helping it regulate its climate, display seasonal variations, and ultimately support life. Astrobiologists say that the same positive aspects should apply to extrasolar planets as well.
Thus far, experts searchi... |

Moons orbiting extrasolar planets may very well hold life, astronomers believe. That is why they are currently expanding their search for extraterrestrial intelligence to include exomoons, given that these celestial bodies are located at the right distance from their parent planets and their stars.
Exomoons have be... |

If the resilience of Earth's lifeforms is any indication, then organisms could survive on Mars as well. Granted, not all areas of Red Planet may be inhabitable, but researchers think that lava tubes may provide the necessary environment for life to endure.
There are two main ways for Mars to have acquired life.... |

When a massive star in the Milky Way's Ophiuchus constellation blew up, it spread rays of light so bright, that they exceeded the brilliance of Mars when they reached Earth, in 1604. Within a few days of the first sighting, the light source was even brighter than Jupiter.
This amazing image was collected using... |

Hydrogen-rich atmospheres may be the key to having liquid water on the surface of a rocky exoplanet, even if the body is located up to 15 astronomical units from its parent star. A new study proposes that greenhouse effects can easily warm such a planet up to the point where it becomes habitable.
Having liquid wate... |

In a recent series of experiments, experts were able to demonstrate that the 20 amino-acids currently making up the basis of all lifeforms were not selected at random. Of the 100+ such molecules, this set proved to be the most efficient. This hints at the fact that life can arise on a whim on other worlds too.For yea... |

Ever since the first lifeforms developed on our planet, their basic components were founded on a specific group of 20 molecules in a group called amino-acids. A particular set of combinations made life possible here, but it could be that different amino-acids did the same on other worlds, experts say.The reason why t... |

According to a new line of thinking among astrobiologists, it may be that one of the main reasons why we have yet to hear from, or make contact with, extraterrestrial civilizations is the fact that powerful, violent cosmic events wiped them out.There are plenty of possible culprits for such a scenario, scientists rev... |
