European Southern Observatory Astronomers Capture New Image Of 47 Tucanae
2013-01-10 15:33:15

[Watch the Video: A close look at the globular star cluster 47 Tucanae] redOrbit Staff & Wire Reports - Your Universe Online Using their Visible and Infrared Survey Telescope for Astronomy (VISTA), astronomers at the European Southern Observatory (ESO) have managed to capture a new infrared image of 47 Tucanae, the second most massive globular cluster in the galaxy. The picture, which was released by the ESO on Thursday, depicts the cluster “in striking detail,” the...

Andromeda Project Wants Your Help Searching For Star Clusters
2012-12-05 13:08:22

Lee Rannals for redOrbit.com - Your Universe Online A new project, named The Andromeda Project, is asking the public's help to search through Hubble Space Telescope images to identify star clusters and increase our understanding of how galaxies evolve. The new project is a collaboration between scientists at the University of Washington, the University of Utah and other partners, aiming to study thousands of high-resolution Hubble images. “It´s an amazing opportunity to...

Orion Nebula Lives Behind Cluster Of Older Stars
2012-11-14 06:26:22

April Flowers for redOrbit.com - Your Universe Online A little over 400 years ago, French astronomer Nicolas-Claude Fabri de Peiresc first discovered the "fog" that is the Orion nebula. Located a mere 1,500 light years from our solar system, the Orion nebula is one of the great wonders of the night sky whose discovery is intimately associated with the early development of telescopes. Scientists have only realized the importance of the nebula in the last 60 years: the Orion nebula, like...

Star Stream Serves As Light Snack For Growing Milky Way
2012-10-27 05:56:42

redOrbit Staff & Wire Reports - Your Universe Online The Milky Way apparently has one voracious appetite, as researchers from a prominent American university have discovered our home galaxy slowly consuming the remnants of an ancient star cluster. Astronomers from Yale University used the Sloan Digital Sky Survey to locate a stream of stars being slowly ingested by the galaxy. While researchers have previously discovered evidence that the Milky Way has gobbled up dwarf galaxies,...

Two Hot Jupiters Found In The Beehive Cluster
2012-09-15 05:07:48

Lee Rannals for redOrbit.com - Your Universe Online According to NASA-funded astronomers, planets can indeed form in dense stellar environments. This evidence comes from the recent discovery of planets that were observed orbiting sun-like stars in a crowded cluster of stars. The newfound planets are not habitable, and are considered to be two hot Jupiters, which are massive gas planets. Each of the hot Jupiter planets circle a different sun-like star in the Beehive Cluster, which is...

Cluster Reveals Its Secrets

[ Video 1 ] | Video 2 ] Lee Rannals for redOrbit.com - Your Universe Online Juan Ponce de León set sail to the Americas to try and find the fountain of youth, but maybe if he had a better telescope he could have just looked up to find it. The European Space Observatory (ESO) released a new image taken by La Silla Observatory in Chile that shows the globular star cluster Messier 4, and one particular star that seems like it belongs in California. The cluster contains...

Galaxy Cluster Sets Record For Star Formation
2012-08-15 12:56:18

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have identified the most massive and luminous galaxy cluster ever found, pumping out 740 new stars per year in the central galaxy. The Phoenix cluster was named after the constellation in which it resides, but its more formal name is SPT-CLJ2344-4243. The galaxy cluster sits seven billion light-years away from Earth, and dwarfs most known clusters.  Aside from its mass and brightness, Michael McDonald, a Hubble...

Stellar Dance Of Ten Billion Years
2012-07-31 12:24:41

redOrbit Staff & Wire Reports - Your Universe Online The NASA/ESA Hubble Space Telescope offers this wonderful view of the crowded stellar encampment called Messier 68 which is a spherical, star-filled region of space known as a globular cluster. Globular clusters to hang together for many billions of years. This is because mutual gravitational attraction among a cluster´s hundreds of thousands or even millions of stars keeps stellar members in check. By looking at the light...

Image 1 - La Silla Observatory Eyes A Cluster Within A Cluster
2012-04-25 11:47:24

[ Video 1 ] | [ Video 2 ] The star cluster NGC 6604 is shown in this new image taken by the Wide Field Imager attached to the MPG/ESO 2.2-meter telescope at the La Silla Observatory in Chile. It is often overlooked in favor of its more prominent neighbor, the Eagle Nebula (also known as Messier 16), that lies a mere wingspan away. But the framing of this picture, which places the star cluster in a landscape of surrounding gas and dust clouds, shows what a beautiful object NGC 6604 is in...

Image 1 - Milky Way’s Companions May Spell Trouble For Dark Matter
2012-04-25 07:46:27

Astronomers from the University of Bonn in Germany have discovered a vast structure of satellite galaxies and clusters of stars surrounding our Galaxy, stretching out across a million light years. The work challenges the existence of dark matter, part of the standard model for the evolution of the universe. PhD student and lead author Marcel Pawlowski reports the team´s findings in a paper in the journal Monthly Notices of the Royal Astronomical Society. The Milky Way, the galaxy we...

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...
