VLT Observations Address the Age of the Universe
The stream of important scientific results from ESOs Very Large Telescope (VLT) at Paranal (Chile) is increasing. Astronomers have had access to the first of the four 8.2-m telescopes since April 1999 and research articles based on observations with this new powerful facility are beginning to appear in larger numbers. The work reported here is one... view more... (1999-12-17)
Largest collection of anomalous white dwarfs observed in new Hubble images
Twenty-four unusual stars, 18 of them newly discovered, have been observed in new Hubble telescope images. The stars are white dwarfs, a common type of dead star, but they are odd because they are made of helium rather than the usual carbon and oxygen. This is the first extensive sequence of helium-core white dwarfs to be observed in a globular... view more... (2009-04-23)
Hubble sees multiple star generations in a globular cluster
Hubble's observations of the massive globular cluster NGC 2808 provide evidence for three generations of stars that formed early in its life. This is a major upset for conventional theories that propose a single period of star birth. view more (2007-05-03)
Astronomers find the most distant star clusters hidden behind a nearby cluster
Astronomers have discovered the most distant population of star clusters ever seen, hidden behind one of the nearest such clusters to Earth. view more (2007-01-11)
Hubble sees faintest stars in a globular cluster
The NASA/ESA Hubble Space Telescope has uncovered what astronomers are reporting as the dimmest stars ever seen in any globular star cluster. view more (2006-08-21)
THE MAKING OF THE MILKY WAY HALO
The brightest objects in the halo are the globular clusters. They are large groupings of stars that were formed together in the very early evolutionary phases of the Milky Way, some 12,000 - 14,000 million years ago. This happened soon after the moment when the first structures emerged in the large cloud of primordial hydrogen in which our Galaxy... view more... (1999-02-18)
Star Family Seen Through Dusty Fog
Images made with ESO's New Technology Telescope at La Silla by a team of German astronomers reveal a rich circular cluster of stars in the inner parts of our Galaxy. Located 30,000 light-years away, this previously unknown closely-packed group of about 100,000 stars is most likely a new globular cluster. view more (2007-03-14)
Hubble yields direct proof of stellar sorting in a globular cluster
A seven year study with the NASA/ESA Hubble Space Telescope has provided astronomers with the best observational evidence yet that globular clusters sort out stars according to their mass, governed by a gravitational billiard ball game between stars. view more (2006-10-25)
UBC astronomers discover how white dwarf stars get their 'kicks'
University of British Columbia astronomer Harvey Richer and UBC graduate student Saul Davis have discovered that white dwarf stars are born with a natal kick, explaining why these smoldering embers of Sun-like stars are found on the edge rather than at the centre of globular star clusters. view more (2007-12-05)
Astronomers see faintest stars in a globular cluster
Astronomers report in the Aug. 18 issue of the journal Science seeing the faintest stars ever seen in any globular star cluster. The light from these dim stars is only as bright as the light produced by a birthday candle on the moon, as seen from Earth. The astronomers used NASA's Hubble Space Telescope. view more (2006-08-21)
Black hole found in enigmatic Omega Centauri
A new discovery has resolved some of the mystery surrounding Omega Centauri, the largest and brightest globular cluster in the sky. Images obtained with the Advanced Camera for Surveys onboard the NASA/ESA Hubble Space Telescope and data obtained by the GMOS spectrograph on the Gemini South telescope in Chile show that Omega Centauri appears to... view more...

Hubble images some of galaxy's dimmest stars
Using the Hubble Space Telescope, astronomers have imaged some of the galaxy's oldest and dimmest stars, offering a rare experimental glimpse of two mysterious star types - tiny, slow burners less than one-tenth the size of our sun and once giant stars that still glow more than 10 billion years after their deaths. view more (2006-08-21)
Galaxy may hold hundreds of rogue black holes
If the latest simulation of what happens when black holes merge is correct, there could be hundreds of rogue black holes, each weighing several thousand times the mass of the sun, roaming around the Milky Way galaxy. view more (2008-01-10)
Astronomers Discover Mysterious New Star Clusters
A UK-led team of astronomers has discovered a completely new type of star cluster around a neighbouring galaxy. view more (2005-04-02)
Astronomers report mysterious giant star clusters
An international team of astronomers reported evidence for the formation of mysterious "super star clusters" Jan. 9 at the annual meeting of the American Astronomical Society in Washington, D.C. view more (2006-01-11)
Common migraine pain condition also prevalent in cluster headache
A pain condition common in people with migraines also has a high prevalence in patients with cluster headache, according to a study conducted by researchers at the Jefferson Headache Center at Jefferson Hospital for Neuroscience. view more (2009-05-28)
First view of a newborn millisecond pulsar?
Combining Hubble Space Telescope images with radio observations has revealed a highly unusual system consisting of a fast spinning pulsar and a bloated red companion star. The existence of the system is something of a mystery - the best explanation so far is that we have our first view of a millisecond pulsar just after it has been `spun up` by... view more...

Bonn astronomers simulate life and death in the universe
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... view more...

Young Stars in Old Galaxies - a Cosmic Hide and Seek Game
Surprise Discovery with World`s Leading Telescopes Combining data from the NASA/ESA Hubble Space Telescope (HST) and the ESO Very Large Telescope (VLT), a group of European and American astronomers have made an unexpected, major discovery. They have identified a huge number of "young" stellar clusters, only a few billion years old , inside an... view more... (2002-06-26)
