The number and disposition of dwarf galaxies and star clusters surrounding the Milky Way is shedding doubt on the existence of dark matter, the stuff believed to make up around a quarter of the Universe's mass-energy budget, and to interact with regular matter solely through the force of gravity.
The objects a... |

A group of astronomers operating a Chile-based ground telescope recently captured an amazing new view of the star cluster dubbed NGC 6604. The cosmic feature, which is oftentimes overlooked in favor of its more famous neighbors, is in fact a sight to behold on its own. The formation is located right next to Messier ... |

Using the NASA/ESA Hubble Space Telescope, a team of astronomers was recently able to image an extremely large star cluster located at the center of the Milky Way. Called Messier 9, the object is located some 25,000 light-years away from Earth, and contains more than 250,000 stars. It was first discovered in 1764 b... |

According to a new proposal made by researchers at the University in Leiden in the Netherlands, it could be that runaway stars in the Milky Way are the products of failed threesomes within extremely crowded star clusters.
In other words, these objects were common stars at first, moving relatively slowly about their... |

While analyzing the star cluster NGC 1929, inside the Large Magellanic Cloud (LMC), astronomers discovered a structure that they refer to as a massive cosmic superbubble. Such formations are fairly rare, as they need a very specific set of conditions in order to develop.
This particular one is produced by a large... |

A study published in the May 20 issue of the esteemed Astrophysical Journal Letters describes what could very well be a new class of star clusters. Experts say that the object known as NGC 6791 cannot be readily classified in any of the existing stellar cluster types. Up until now, astronomers used to divide any new ... |

Until not long ago, astronomy students were taught that globular clusters are accumulations of stats that formed from the same massive gas cloud. As such, no new stars could develop beyond the time of initial formation. This notion was however proven wrong in a new study.The research looked at a large number of such ... |

An international astronomical collaboration managed to discover one of the brightest, most luminous stars in the entire Universe. The object, dubbed VFTS 682, lies in the dwarf galaxy Large Magellanic Cloud, and is around 300 million times brighter than our Sun.While finding super-bright stars is nothing new for astr... |

Recent observations of the Pleiades open star cluster have revealed a star system that contains thousands of times more dust than around our Sun. The finding could imply that recent planetary collisions crippled the star's surroundings. In a related finding, other stars in the cluster were determined to experien... |

Astronomers say that a new method of determining the age of stars will soon be made available to experts around the world. A group of them says that analyzing stellar spin rates could provide useful data for establishing the true age of a given star. In numerous points in the long lives, stars similar to our Sun look... |

While investigating the central regions of the Milky Way using an interferometer telescope, astronomers were able to detect traces of stellar fossils that appeared to have been produced by what could best be termed as cosmic intruders. These objects most certainly did not originate inside the galaxy, astronomers say.... |

For many years, astronomers have believed that elliptical galaxies formed through the collision of two or more, smaller spiral galaxies during a catastrophic event. Experts now propose an alternative mechanism that may have yielded the same result, and which does not require collisions.Ellipticals are galaxies that c... |

If you are interested in looking for star clusters, then the times when the Moon is out of the evening skies, such as the current ones, are the best for observations. Using a pair of good binoculars, amateur astronomers can easily detect several famous structures of this class.
Some interesting star clusters can ... |

A team of experts has recently determined that massive stars, tens to hundred of times the mass of our own Sun, can form nearly everywhere, including in what astronomers would call isolation.
These conclusions belong to a new study carried out by astronomers at the University of Michigan in Ann Harbor, who looked ... |

A team of astronomers proposes that the main reason why experts cannot find hot Jupiter-class exoplanets around stars in clusters is the fact that these cosmic fireballs have already destroyed them.Very few of the numerous studies conducted on such parent stars have evidenced the existence of occultations, which is a... |

Scientists are currently puzzled at a recent discovery they made, when they found out that a rare type of neutron star, called a magnetar, was produced from a massive star about 40 times heavier than the Sun.The finding is interesting because, according to accepted theories, a star this heavy should have collapsed in... |

In spite of cataloging all deep-sky objects as things that could be mistaken for comets, famed astronomer Charles Messier somehow managed to miss adding the Double Cluster on his list. As such, the structure now doesn't have an “M” number, unlike most of its neighbors. While Messier ignored the struc... |

Established astronomical knowledge had it that galaxies with two nuclei were very rare. Experts believed that small galaxies had one made up of a star cluster, whereas the more massive ones had a black hole at their cores. But a new study comes to prove that the double-nucleus galaxy is, in fact, not that rare of an ... |

An astronomer once estimated that, if someone counted every grain of sand existing on all the beaches on Earth, it would not be enough to equal the enormous number of galaxies observed in the visible universe. But even with such a high number of galaxies visible on the sky, young galaxies that can reveal how the spir... |
