Organic compounds contain carbon and hydrogen and form the building blocks of all life on Earth. By analyzing organic material and minerals in the Martian meteorite Allan Hills 84001, scientists have shown for the first time that building blocks of life formed on Mars early in its history. Previously, scientists have thought that organic material in ALH 84001 was brought to Mars by meteorite impacts or more speculatively originated from ancient Martian microbes. picked by AutumnLotus 10 months ago tags building blocks life mars organic compounds carbon |

For the first time, satellite imagery reveals thick Martian salt deposits scattered across the planet's southern surface, which one planetary scientist claims could be sites of ancient life. The mats of sodium chloride — the same taste-enhancing mineral found on your kitchen table — serve as more evidence of Mars' watery past, and researchers think the briney pools that made them could... read full post picked by AutumnLotus 7 months ago 4 comments edit related share science |

Scientists have found signs that water may once have gurgled up through the Martian soil in hydrothermal vents similar to those in Yellowstone National Park. picked by AutumnLotus 5 months ago 0 comments edit related share science |

The longstanding mystery of how oceans once formed on Mars could be solved by fire and brimstone. Specifically, researchers now suggest that ancient volcanoes could have released brimstone — now more commonly known as sulfur — that warmed up the red planet enough for liquid water oceans in the early days of Mars. These findings might also shed insight on the young Earth, including the ... read full post picked by AutumnLotus 10 months ago 0 comments edit related share plime.com |

Astronomers at the Carnegie Institution have found the first indications of highly complex organic molecules in the disk of red dust surrounding a distant star. The eight-million-year-old star, known as HR 4796A, is inferred to be in the late stages of planet formation, suggesting that the basic building blocks of life may be common in planetary systems. picked by AutumnLotus 9 months ago 0 comments edit related share plime.com |

NASA scientists have discovered what might form some of the weirdest landscapes on Mars, winding channels carved into the Martian surface that scientists have dubbed "spiders," "lace" and "lizard skin." The unusual landscape features form in an area of Mars' south pole called cryptic terrain because it once defied explanation.

Fossil microbes found along an iron-rich river in Spain reveal how signs of life could be preserved in minerals found on Mars. The discovery may help to equip the next generation Mars rover with the tools it would need to find evidence of past life on the planet. picked by AutumnLotus 6 months ago 0 comments edit related share science |

Scientists analysing data gathered by the Cassini spacecraft have confirmed the presence of heavy negative ions in the upper regions of Titan’s atmosphere. These particles may act as organic building blocks for even more complicated molecules and their discovery was completely unexpected because of the chemical composition of the atmosphere (which lacks oxygen and mainly consists of nitrogen... read full post picked by AutumnLotus 10 months ago 1 comments edit related share plime.com |

An important discovery has been made with respect to the mystery of "handedness" in biomolecules. Researchers found that some of the possible abiotic precursors to the origin of life on Earth have been shown to carry "handedness" in a larger number than previously thought. They studied the organic materials of a special group of meteorites that contain among a variety of compou... read full post picked by AutumnLotus 7 months ago 1 comments edit related share science |

A primitive star has been born in the heart of a computer, revealing how the basic building blocks of life were present soon after the Big Bang some 13.7 billion years ago. Stars convert light elements such as helium and hydrogen into the heavier elements necessary for life and it has often been remarked that human beings are glorified stardust. picked by AutumnLotus 2 months ago 0 comments edit related share science |

Organic molecules – in the form of methane – have been detected on a planet outside our solar system for the first time. The giant planet lies too close to its parent star for the methane to signal life, but the detection offers hope that astronomers will one day be able to analyse the atmospheres of Earth-like worlds. picked by AutumnLotus 8 months ago 5 comments edit related share science |

New research raises the possibility that Mars could awaken from within -- three large Martian volcanoes may only be dormant, not extinct. Volcanic eruptions release lots of greenhouse gasses, like carbon dioxide, into the atmosphere. If the eruptions are not complete, and future eruptions are large enough, they could warm the Martian climate from its present extremely cold and dry state. picked by AutumnLotus 12 months ago 0 comments edit related share plime.com |
