Latest Star cluster Stories
Like a July 4 fireworks display a young, glittering collection of stars looks like an aerial burst.
By exploiting the exquisite image quality of the NASA/ESA Hubble Space Telescope and comparing two observations made ten years apart astronomers have, for the first time, managed to measure the tiny motions of several hundred young stars within the central cluster of the star-forming region NGC 3603.
Around a quarter of the globular star clusters in our Milky Way galaxy are invaders from other galaxies, according to a team of scientists from Swinburne University of Technology in Australia.
Just in time for the holidays: a Hubble Space Telescope picture postcard of hundreds of brilliant blue stars wreathed by warm, glowing clouds.
In a break from its usual task of searching for distant cosmic explosions, NASA's Swift satellite has acquired the highest-resolution view of a neighboring spiral galaxy ever attained in the ultraviolet.
Using ESOâ€™s Very Large Telescope, astronomers have obtained one of the sharpest views ever of the Arches Cluster â€” an extraordinary dense cluster of young stars near the supermassive black hole at the heart of the Milky Way.
New calculations by Ryan O'Leary and Avi Loeb (Harvard-Smithsonian Center for Astrophysics) suggest that hundreds of massive black holes, left over from the galaxy-building days of the early universe, may wander the Milky Way.
On long, dark winter nights, the constellation of Orion the Hunter dominates the sky. Within the Hunterâ€™s sword, the Orion Nebula swaddles a cluster of newborn stars called the Trapezium.
The festive season has arrived for astronomers at the European Southern Observatory (ESO) in the form of this dramatic new image.
Omega Centauri has been known as an unusual globular cluster for a long time. A new result obtained by the NASA/ESA Hubble Space Telescope and the Gemini Observatory reveals that the explanation behind omega Centauri's peculiarities may be a black hole hidden in its center. One implication of the discovery is that it is very likely that omega Centauri is not a globular cluster at all, but a dwarf galaxy stripped of its outer stars, as some scientists have suspected for a few years.
Omega Centauri -- Discovered by Edmond Halley in 1677. About 10 million stars orbit the center of this globular cluster - named Omega Centauri - as this giant globular cluster orbits our Galactic center. Recent evidence indicates that Omega Centauri is by far the most massive of the about 150 known globular clusters in the Milky Way. Omega Centauri, cataloged as NGC 5139, spans about 150 light years across, lies about 15,000 light years away, and can be seen without visual aid...
The Hyades -- The Hyades are an open star cluster located in the constellation Taurus. The closest star cluster to Earth, it is centered some 151 light years away. The brightest star in this direction is Aldebaran, but it is not a member of the cluster, being located at just over 40% of the distance. Not counting Aldebaran, approximately 300 stars are known or suspected to be members of the cluster; most are not visible to the naked eye. The stars of the Hyades are associated with one...
