Finding planets orbiting stars at great distances from our solar system is not an easy job, but there seems to be many of them out there, according to recent observations. And that's a great thing, since it's actually harder than finding a needle in a hay stack. It's more like looking for a firefly fly... |

No telescope can form a perfect image. Even if a reflecting telescope could have a perfect mirror, or a refracting telescope could have a perfect lens, the effects of aperture diffraction could still not be escaped.The blurring effect from the atmosphere is among the most important distortions that affect telescopes... |

NASA has just released a spectacular photo of thousands of galaxies gathered in a sort of family album. This picture is a symbol of the technology being used by astronomers worldwide to capture a glimpse of the vast universe that surrounds us, and of the progress mankind has made in the last centuries. There are pro... |

How can astronomers perceive depth in space when determining the distance to certain mysterious bodies in and around our Milky Way galaxy? Well, using only one telescope doesn't really do the job so they use a mathematical solution that looks more like an optical illusion.Astronomers use NASA's Spitzer... |

SETI is an acronym for Search for Extra-Terrestrial Intelligence, the collective name for a number of organized efforts to detect Extraterrestrial life. The project aims to survey the sky to detect the existence of transmissions from a civilization on a distant planet.The institute is planning to have 42 radio astro... |

A new proposition in the field of astronomical observations is getting mixed opinions. An American astronomer is proposing that we build a giant liquid-mirror telescope on the Moon, saying that it will be hundreds of times more accurate and sensitive than even the Hubble Space Telescope.Roger Angel, a member of the ... |

Astronomers have received pictures showing two of Saturn' 27 moons, one passing in front of the other. This is considered very important for scientific calculations, as it is the only way that the mass of the moons can be approximated.With the help of the Faulkes Telescope South in Australia, astronomers observ... |

NASA's Spitzer Space Telescope has delivered a spectacular image revealing the birth of new stars in the Orion galaxy, a famous constellation visible in winter from the northern hemisphere. They are the result of shockwaves that occurred 3 million years ago when a massive star exploded.The Orion constellation, a... |

Hubble Space Telescope has just discovered a gigantic, ghostly ring of dark matter at a distance of 5 billion light-years from Earth. So far, it's the most compelling evidence of the existence of the elusive dark matter.Scientists have theorized on the existence of dark matter for some time, and they think it&#... |

The Hubble Space Telescope (HST) is a telescope in orbit around the Earth, named after astronomer Edwin Hubble. Its position outside the Earth's atmosphere provides significant advantages over ground based telescopes - images are not blurred by the atmosphere, there is no background light scattered from the atm... |

The Lyrid meteor shower will peak this weekend, in the morning of April 22 and 23. The Lyrids are a strong meteor shower lasting from April 15th to April 28th each year. The radiant of the meteor shower is located in the constellation Lyra. It peaks at April 22th. The source of the meteor shower is the periodic Com... |

The Pleiades' high visibility in the night sky has guaranteed it a special place in many cultures, both ancient and modern. In Greek mythology, they represented the Seven Sisters, while to the Vikings, they were Freyja's hens, and their name in many old European languages compares them to a hen with chicks... |

A new NASA mission planned for, with an assist from Utah State University, will send a satellite into orbit to study what are known as noctilucent clouds (night shining, in Latin), which appear to glow at night. Forming at the edge of space, they appear to be getting brighter and more frequent, raising questions as ... |

Chandra telescope observations of the galaxy NGC 1365, a galaxy located 60 million light-years away have captured a remarkable eclipse of the supermassive black hole at its center. A dense cloud of gas passed in front of the black hole, which blocked high-energy X-rays from material close to the black hole.Just as e... |

Until now, scientists have used various techniques to detect more than 200 exoplanets. Most of these exoplanets are from five to 4,000 times more massive than Earth, and are either too hot, too cold or too much of a giant gas ball to be considered likely habitats for life. So far, no one has managed to capture an im... |
