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...

Star Cluster Could Help Astronomers Find Earth-Like Planets
2012-06-23 06:15:20

A loose star cluster located approximately 800 to 1,000 light years from Earth, detected by scientists more than 180 years ago but never analyzed in detail, could be vital in helping experts not only to understand how stars like the Sun evolve, but also to help them in the search for Earth-like planets. According to a June 22 press release, researchers from Penn State University and colleagues from the University of California, Santa Cruz (UCSC); Yale University; and the California...

Birth Environment Affects Star Formation
2012-05-12 04:34:32

Researchers working at the University of Bonn in Germany have used computer simulations to discover the first evidence that the way in which stars form depends upon the conditions of their birth environments, claims a new study published in the journal Monthly Notices of the Royal Astronomical Society. In a Friday statement, the Society said that the properties of stars, which are believed to form in interstellar space from gas and dust clouds, are dependent upon the surrounding conditions...

Cluster Of Stars Survived Massacre 13 Billion Years Ago
2012-02-14 13:37:27

Astronomers have found a cluster of stars that they say survived a massacre 13 billion years ago. The team used computer simulations to look at how the compact groups of stars surrounding our Milky Way galaxy were formed. There are about 200 compact groups sitting close to our galaxy, each containing up to a million stars. The researchers ran simulations of isolated and colliding galaxies, in which they included a model for formation and destruction of stellar clusters. Once a...

Astronomers discover how mysterious stars stay so young Mysterious “blue stragglers” are old stars that appear younger than they should be: they burn hot and blue. Several theories have attempted to explain why they don´t show their age, but, until now, scientists have lacked the crucial observations with which to test each hypothesis. Armed with such observational data, two astronomers from Northwestern University and the University of Wisconsin-Madison report that a...

Image 1 - VISTA Finds New Globular Star Clusters

Sees right through the heart of the Milky Way [ Watch Video 1 ] | [ Watch Video 2 ] Two newly discovered globular clusters have been added to the total of just 158 known globular clusters in our Milky Way. They were found in new images from ESO´s VISTA survey telescope as part of the Via Lactea (VVV) survey. This survey has also turned up the first star cluster that is far beyond the center of the Milky Way and whose light has had to travel right through the dust and gas in the...

How Did Single Stars Lose Their Companions
2011-09-16 07:12:23

  Not all stars are loners. In our home galaxy, the Milky Way, about half of all stars have a companion and travel through space in a binary system. But explaining why some stars are in double or even triple systems while others are single has been something of a mystery. Now a team of astronomers from Bonn University and the Max-Planck-Institute for Radio astronomy (also in Bonn) think they have the answer — different stellar birth environments decide whether a star holds on to...

ESO's infrared survey telescope digs deep into star-forming regions in our Milky Way Using data from the VISTA infrared survey telescope at ESO's Paranal Observatory, an international team of astronomers has discovered 96 new open star clusters hidden by the dust in the Milky Way. These tiny and faint objects were invisible to previous surveys, but they could not escape the sensitive infrared detectors of the world's largest survey telescope, which can peer through the dust. This is the first...

WASHINGTON, May 25, 2011 /PRNewswire-USNewswire/ -- NASA's Hubble Space Telescope has found a rare class of oddball stars called blue stragglers in the hub of our Milky Way, the first detected within our galaxy's bulge. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Blue stragglers are so named because they seemingly lag behind in the aging process, appearing younger than the population from which they formed. While they have been detected in many distant star clusters, and...

For the first time, a team of astronomers has succeeded in investigating the earliest phases of the evolutionary history of our home Galaxy, the Milky Way. The scientists, from the Argelander Institute for Astronomy at Bonn University and the Max-Planck Institute for Radioastronomy in Bonn, deduce that the early Galaxy went from smooth to clumpy in just a few hundred million years. The team publish their results in the journal Monthly Notices of the Royal Astronomical Society. Led by...

Star Cluster -- Star clusters are physically bound systems of stars. In order of low compactness to high compactness (and in some sense also age) they range from stellar associations to open clusters to globular clusters. Star clusters are held together by the gravitation of their members. Due to both external (encounters with massive objects, influence of the host galaxy) and internal (encounters with other cluster members, stellar evolution) influences, clusters slowly evaporate. Their...

Open Cluster -- An open cluster is a group of star formed from a molecular cloud, the illuminated parts of which we see as one or more nebulae. They are also called galactic clusters since they exist within the galaxy. All the stars in an open cluster have more or less the same age and the same chemical composition, so any difference between them is solely due to their mass. Most open clusters are dominated by their O-type and B-type giant blue stars, which are very luminous but...

Globular Cluster -- A globular cluster is a cluster of stars that is spherical in shape and extremely dense towards its core. Globular clusters are usually composed of hundreds of thousands of old stars, similar to the bulge of a spiral galaxy but confined to a volume of only a few cubic parsecs. Some globular clusters (like Omega Centauri in our Milky Way, and G1 in M31) are truly massive clusters, with several million times the mass of our Sun. Such globular clusters may be the...

Milky Way Galaxy -- The Milky Way (a translation of the Latin Via Lactea, in turn derived from the Greek Galaxia (gala, galactos means "milk")) is a hazy band of white light across the night sky formed by billions of stars in the disc of our galaxy. The Milky Way appears brightest in the direction of Sagittarius, where the galactic centre lies. Relative to the celestial equator, the Milky Way passes as far north as the constellation of Cassiopeia and as far south as the constellation of...
