A team of researchers has just completed a new investigation on how our planet would have looked like to a distant observer during the time of the dinosaurs. What this means is that the experts sought to figure out precisely how bright our world appeared to potential aliens on extrasolar planets.
Rather than use cl... |

Experts at the Rice University say that imperfect carbon nanotubes are the most likely to exhibit dips in brightness when viewed by external observers. Perfect CNT displays are the brightest, a trait that could be very useful in applications such as advanced sensors.
Length and imperfections were found to be the tw... |

Investigators at the Niels Bohr Institute announce the discovery of some low surface brightness galaxies, in a finding that proves these structures are more common throughout the Universe than anyone originally thought. These galaxies stand out through the fact that they are very small, but also because experts have ... |

Astronomers have now set their eyes on developing methods of identifying signs of multicellular life on the extrasolar planets they are seeing. To that end, a group of experts recently developed a new mathematical technique, that could allow for scientists to identify such objects. In the early days of exoplanetary r... |

The Epsilon Aurigae star system is a peculiar stellar formation, astronomers say. For many years, scientists have been pointing their instruments at it, in hopes of gaining additional insight into how the structure actually looks like. Many have hypothesized that the system is a binary, but thus far pieces of evidenc... |

When it comes to studying older Sun-like stars, astronomers suddenly find themselves in a bind. They say that their instruments start picking up unusual fluctuations in the stars' brightness. They add that, if they investigate the phenomenon even deeper, then more mystery is added to the original one, and very l... |

Polaris, whose vibrations seem to have almost completely decreased this past century, appears now to have resumed its activity, although astronomers don't quite understand what is triggering the process. Polaris, also known as the Northern Star, is a Cepheid variable star that varies its brightness every four da... |

Eta Carinae is still viewed by most astronomers as the galaxy's brightest known star, albeit lately a new contender for that title was discovered in the Peony nebula, towards the Milky Way's center. Now, NASA's Spitzer Space Telescope pierced through one of the dustiest regions of the galaxy to show ex... |

Two years after it was stripped of its privileges as a planet, Pluto takes a new hit coming from the International Astronomical Union which has taken it out of the dwarf planet family and placed it into a rather strange new one called 'plutoids'. The IAU decided in 2006 that Pluto should be demoted from the... |

With the help of the Very Large Telescope on top of the Paranal mountain, European Organization for Astronomical Research in the Southern Hemisphere astronomers have solved possibly one of the biggest mysteries related to the existence of the WOH G64 star, located in the near Large Magellanic Cloud galaxy. It appears... |

The Holy Bible describes how just before Jesus was born a star appeared to the East, guiding the Magi towards his birth place. That's fine from a religious point of view. However, astronomers are more curios when it comes to unexplained cosmic events such as the sudden appearance of a star on the sky. So, over t... |

Mysterious observations of variable stars have recently been made by astronomers. The unusual thing about these stars is the fact that they change in brightness, increasing and then rapidly decreasing it. They think there may be a new category of stars, whose brightening events are dimmer than the cataclysmic explos... |

Neptune is the eighth and farthest known planet from the Sun in the Solar System. Named after the Roman god of the sea, it is the fourth largest planet by diameter and the third largest by mass, having 17 times the mass of Earth.One of the coldest planets in the solar system, with an atmospheric temperature close to... |
