Some strange and bright flashes of light appearing on the surface of the Moon have been puzzling astronomers for centuries. The first reports of bright spots and distortions on the surface that appeared with no apparent cause and disappeared again were made in 1540.In the 1950s and 1960s, there was a huge interest f... |

The history of aviation, though short (only a bit more than a century) has known the greatest advances in terms of design technology, building materials and performances of civilian and military aircraft. The first planes were made of wood, cardboard and cloth, now they are built using the latest development in arti... |

A new image of the Rosette Nebula shows some remarkable cosmic dust sculptures, full of colors, testimony of the beauty of the universe in its inner working. Rosette Nebula, a nebulosity closely associated with the open cluster NGC 2244. Actually, the open cluster lies within the nebula, and it was discovered by Joh... |

Many people are beginning to realize that global warming is not going to go away by itself, as engines that burn gasoline emit pollutants, such as carbon dioxide, that cause global warming.Moreover, fossil fuels that took millions of years to form are rapidly depleting and can't regenerate overnight. For exampl... |

A strange thing happens at the very core of our galaxy. It seems that a spinning bar of material may be throwing nearby stars outwards as it rotates and most of them are heading towards our solar system. Fortunately, none of these stars has any chance of actually reaching us.A team of researchers led by Thomas Bensb... |

A team of astronomers discovered amazing evidence of a brutal disruption in a huge galaxy cluster, a bright arc of ferociously hot gas that extends more than two million light years and must have been produced by one of the most energetic events ever detected.Led by Ralph Kraft of the Harvard-Smithsonian Center for ... |

A newly discovered exoplanet puzzles astronomers. Named XO-1b, the planet is the most massive found orbiting extremely close to its star, but it doesn't have a circular orbit, like most astronomers would have expected, but an elliptical one, which is very unusual, considering the short distance to its sun.Disco... |

A mystery about the interior of the Sun lasting for centuries has been solved by scientists at National Science Foundation (NSF) and NASA. They now proved that sound waves escape the interior of the sun and form fountains of hot gas that shape and provide fuel for a region of the sun's atmosphere.This thin regi... |

A new study performed by astronomers involved in the search for extrasolar planets revealed that there are more chances of a star having Jupiter-like gas giants orbiting around them when the star itself is more massive than our Sun.It seems that the 10 observations of stars which are more massive than our own suppo... |

A new research is trying to find our Sun's family tree throughout the complex history of the galaxy, by studying its chemical composition. Open clusters could also provide clues concerning the Sun's genealogy.The team, led by Gayandhi De Silva, at the European Southern Observatory's Very Large Telesco... |

Scientists have created a device that can map magnetic fields more accurately than ever, using an ultra-cold gas confined to a laser beam. It's based on ultra-cold Bose Einstein condensates (BECs) and can precisely measure low-frequency fields, like brain waves at an incredibly high resolution and sensitivity.D... |

Recently, scientists were able to polarize noble gases, (rare gases like Helium, Neon, Argon and Xenon) and to take MRI machine pictures of lungs that had inhaled these gases. A new technique can polarize other elements too, with even greater benefits to medical science. Spin polarization is the degree by which the ... |

The nature of the interstellar medium has received the attention of astronomers and scientists over the centuries. It is not at all a void; on the contrary, there are many particles floating in space. The interstellar medium (or ISM) is the name astronomers give to the gas and dust that pervade interstellar space. W... |

Nature has found complex models long before humans discovered them and most of them are more effective than the human ones. The three-dimensional shells of tiny ocean algae, called diatoms, could offer the foundation for novel electronics, like gas sensor devices that could be faster and more efficient than conventio... |
