Petal-like Shells And Strange Star Clusters
2013-10-10 11:08:51

[ Watch The Video: Zooming in on PGC 6240 ] [ Watch The Video: Panning across PGC 6240 ] NASA/ESA Hubble Space Telescope PGC 6240 is an elliptical galaxy that resembles a pale rose in the sky, with hazy shells of stars encircling a very bright center. Some of these shells are packed close to the center of the galaxy, while others are flung further out into space. Several wisps of material have been thrown so far that they appear to be almost detached from the galaxy altogether....

WASHINGTON, Sept. 12, 2013 /PRNewswire-USNewswire/ -- NASA's Hubble Space Telescope has uncovered the largest known population of globular star clusters, an estimated 160,000, swarming like bees inside the crowded core of the giant grouping of galaxies known as Abell 1689. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) An international team of astronomers used Hubble's Advanced Camera for Surveys to discover this bounty of stellar fossils and confirm such compact...

Old Age Makes Monster Galaxies Picky Eaters

Brett Smith for redOrbit.com - Your Universe Online A new analysis from scientists at NASA's Jet Propulsion Laboratory (JPL) revealed that supermassive galaxies have stopped cannibalizing their neighbors over the past few billion years. The finding calls current models for galactic growth into question. "We've found that these massive galaxies may have started a diet in the last 5 billion years, and therefore have not gained much weight lately," said Yen-Ting Lin of the Academia Sinica...

Predicting The End Of Stars Relies On How Much Sodium They Have
2013-05-29 12:58:12

[WATCH VIDEOS: A Close Look At NGC 6752 | Zooming In On NGC 6752] Lee Rannals for redOrbit.com — Your Universe Online An international team of astronomers published a paper today in the journal Nature detailing the role sodium plays in determining how stars evolve and how they end their lives. Astronomers believe that stars like the Sun will blow off much of their atmospheres into space near the ends of their lives, which is known as asymptotic giant branch (AGB). However, new...

Astronomers Focus In On Recently Formed Stars In The Southern Constellation Of Vela
2013-03-27 06:18:20

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have unveiled a new image of recently formed bright blue stars in the cluster NGC 2547. Astronomers using the Wide Field Imager on the MPG/ESO 2.2-meter telescope at the European Space Observatory's (ESO) La Silla Observatory in Chile took images of the stars while they were focusing in on the southern constellation of Vela (The Sail). Despite the universe being roughly 13.8 billion years old, new stars and objects are...

Crowded Star Clusters Defy Simple View Of Gravity
2013-02-21 09:00:07

April Flowers for redOrbit.com - Your Universe Online On large astronomical scales, gravity remains the dominant force acting on heavenly bodies, from asteroids and exoplanets to solar systems and supermassive black holes. But when it comes to young stars in clustered galaxies, researchers have found that the dynamics of these crowded environments cannot be fully accounted for by simple understanding of gravity. A new study, led by the“¯Kavli Institute for Astronomy and...

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...

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...
