For years scientists have wrestled with a puzzling fact: The universe appears to be remarkably suited for life. Its physical properties are finely tuned to permit our existence. Stars, planets and the kind of sticky chemistry that produces fish, ferns and folks wouldn't be possible if some of the cosmic constants were only slightly different. Well, there's another property of the universe that's equally noteworthy: It's set up in a way that keeps everyone isolated. picked by AutumnLotus 10 months ago tags aliens apart universe life stars planets |

Hundreds of millions — or even billions — of years after planets would have initially formed around two unusual stars, a second wave of planetesimal and planet formation appears to be taking place. "This is a new class of stars, ones that display conditions now ripe for formation of a second generation of planets, long, long after the stars themselves formed." picked by AutumnLotus 9 months ago 0 comments edit related share science |

Stars always evolve in the universe in large groups, known as clusters. Astronomers distinguish these formations by their age and size. The question of how star clusters are created from interstellar gas clouds and why they then develop in different ways has now been answered by researchers at the Argelander Institute for Astronomy at the University of Bonn with the aid of computer simulations. picked by AutumnLotus 12 months ago 0 comments edit related share plime.com |

View the Milky Way at 10 million light years from the Earth. Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. After that, begin to move from the actual size of a leaf into a microscopic world that reveals leaf cell walls, the cell nucleus, ch... read full post picked by wags273 9 months ago 2 comments edit related share science |

New research shows that black holes are not the ultimate destroyers that are often portrayed in popular culture. Instead, warm gas escaping from the clutches of enormous black holes could be one source of the chemical elements that make life possible. picked by AutumnLotus 1 year ago 0 comments edit related share science |

Galaxies tend to give birth to their stars on the road, while travelling down intergalactic highways towards cosmic cities called galaxy clusters, new Spitzer Space Telescope observations reveal. Galaxies in relatively empty regions of the universe flock towards densely populated galaxy clusters, attracted there by the clusters' gravity. picked by AutumnLotus 9 months ago 0 comments edit related share science |

Rocky extrasolar planets thought to be half frozen and half scorched might instead rock back and forth, creating large swaths of twilight with temperatures suitable for life. picked by AutumnLotus 10 months ago 0 comments edit related share plime.com |

Ever wanted to fly between the stars? Check out the rivers on Mars? Follow a comet as it flys around the sun? Zoom out and watch the entire galaxy from afar? Now you can! You can search anything, follow, zoom, speed/slow time and it's easy to use, just like Google Earth. picked by Boomshank 2 years ago 2 comments edit related share science |

Rocky planets, possibly with conditions suitable for life, may be more common than previously thought in our galaxy, a study has found. New evidence suggests more than half the Sun-like stars in the Milky Way could have similar planetary systems. picked by mahler87 8 months ago 0 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 |

Perhaps the first stars in the newborn universe did not shine, but instead were invisible “dark stars” 400 to 200,000 times wider than the sun and powered by the annihilation of mysterious dark matter. The study calculated how the birth of the first stars almost 13 billion years ago might have been influenced by the presence of dark matter – the unseen, yet-unidentified stuff tha... read full post picked by AutumnLotus 10 months ago 2 comments edit related share plime.com |

Dusty infrared galaxies are cosmic "nurseries" for some of the universe's hottest young stars -- and new research from NASA's Spitzer Space Telescope shows that when the universe was approximately six billion years old, these galaxies packed into the densest "zip codes" in space.

Scientists have known for some time that most major groups of complex animals appeared in the fossils record during the Cambrian Explosion, a seemingly rapid evolutionary event that occurred 542 million years ago. Now paleontologists have identified another explosive evolutionary event that occurred about 33 million years earlier among macroscopic life forms unrelated to the Cambrian animals. They... read full post picked by AutumnLotus 9 months ago 1 comments edit related share science |

Picture a cool place, teeming with a multitude of hot bodies twirling about in rapidly changing formations of singles and couples, partners and groups, constantly dissolving and reforming. If you were thinking of the dance floor in a modern nightclub, think again. It's a description of the shells around dying stars, the place where newly formed elements make compounds and life takes off. picked by AutumnLotus 1 year ago 3 comments edit related share plime.com |
