[ Watch The Video: Zooming in on the Bright Star Cluster Messier 7 ] ESO Messier 7, also known as NGC 6475, is a brilliant cluster of about 100 stars located some 800 light-years from Earth. In this new picture from the Wide Field Imager on the MPG/ESO 2.2-meter telescope it stands out against a very rich background of hundreds of thousands of fainter stars, in the direction of the center of the Milky Way. At about 200 million years old, Messier 7 is a typical middle-aged open...

ESO Researchers Discover Three New Planets In Messier 67

[ Watch the Video: Messier 67 A Perfect Lab For Studying Planet Formation ] Gerard LeBlond for redorbit.com - Your Universe Online There have been more than one thousand planets confirmed outside our Solar System, but only a few are within star clusters. Using the European Southern Observatory’s (ESO) HARPS instrument, researchers have found three new planets in the star cluster Messier 67. Of these three newly discovered planets, two have been found orbiting stars similar to our sun....

New Black Hole In GLobular Cluster

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have discovered a new black hole candidate sitting inside a globular cluster known as M62. The latest discovery, reported in the Astrophysical Journal, adds weight to the argument that black holes are a common occurrence in these star clusters. Astronomers discovered two black holes in a globular cluster, known as M22, last year . "This implies that the discovery of the other black hole, in the globular cluster called...

[ Watch the Video: Zoom into 47 Tucanae ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers using NASA's Hubble Space Telescope are tracking the orbital motion of 33,000 stars in one of the Milky Way's oldest globular clusters. The team will be using the space observatory to track the orbital motion of 33,000 stars within globular cluster 47 Tucanae, which sits over 16,000 light-years away from Earth. "When analyzing the motions of stars, the longer the time baseline...

European Southern Observatory Astronomers Capture New Image Of 47 Tucanae

[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...

Star Clusters Can Look Younger Than They Are

Lee Rannals for redOrbit.com - Your Universe Online Just as your lifestyle can cause you to show your age, the same is true for star clusters, according to a study published in the journal Nature. Astronomers using the Hubble Space Telescope have found that some globular clusters are still young at heart, despite being relics of the early Universe. Globular clusters are spherical collections of stars that are held tightly together by their mutual gravitational attraction....

Globular Star Cluster NGC 6362

[ Video 1 ] | [ Video 2 ] European Southern Observatory Photo Release This colorful view of the globular star cluster NGC 6362 was captured by the Wide Field Imager attached to the MPG/ESO 2.2-meter telescope at ESO´s La Silla Observatory in Chile. This new picture, along with a new image of the central region from the NASA/ESA Hubble Space Telescope, provide the best view of this little-known cluster ever obtained. Globular clusters are mainly composed of tens of thousands of very...

Messier 22 Has Two Black Holes

Lee Rannals for redOrbit.com - Your Universe Online A surprising black hole discovery made while using the National Science Foundation's Karl G. Jansky Very Large Array (VLA) is causing scientists to change what they know of globular star clusters. Astronomers used VLA to study the globular cluster known as Messier 22, which is a tight-knit collection of hundreds of thousands of stars that lie 10,000 light-years away from Earth. The team had hoped to find evidence for a rare type of...

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...
