Droplets of star formation

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online As astronomers have sought to understand the formation and evolution of galaxies, a handful of simple truths have emerged. Despite many questions remaining, we know that galaxies form in clusters, and create interlinked chains and structures that create a spider web across the cosmos. [ Watch the Video: Hubblecast 76: Merging Galaxies And Droplets Of Starbirth ] Because they often move through the Universe in such close...

WASHINGTON, July 10, 2014 /PRNewswire-USNewswire/ -- NASA's Hubble Space Telescope has photographed an unusual structure 100,000 light years long, which resembles a corkscrew-shaped string of pearls and winds around the cores of two colliding galaxies. http://photos.prnewswire.com/prnvar/20081007/38461LOGO The unique structure of the star spiral may yield new insights into the formation of stellar superclusters that result from merging galaxies and gas dynamics in this rarely seen...

elliptical galaxy M87
2014-04-30 12:25:17

Harvard-Smithsonian Center for Astrophysics The galaxy known as M87 has a fastball that would be the envy of any baseball pitcher. It has thrown an entire star cluster toward us at more than two million miles per hour. The newly discovered cluster, which astronomers named HVGC-1, is now on a fast journey to nowhere. Its fate: to drift through the void between the galaxies for all time. "Astronomers have found runaway stars before, but this is the first time we've found a runaway star...

What Lies Beyond: Astronomer Maps Galaxies Near Our Own

Lee Rannals for redOrbit.com - Your Universe Online A new paper published in the Monthly Notices of the Royal Astronomical Society has broadened the view of what lies just past our galaxy. The Milky Way and Andromeda are dominant members of a small group of galaxies. However, not a lot has been known about the smaller galaxies that reside within our neighborhood in the universe. York University Physics & Astronomy Professor Marshall McCall was able to map out the bright galaxies...

Red Dead Redemption: Black Holes Bully Galaxies Into Submission
2014-02-26 15:13:15

Brett Smith for redOrbit.com - Your Universe Online Typically filled with only the oldest stars, which are relatively low in mass and appear red, giant elliptical galaxies have long baffled astronomers. These galaxies are mysteriously shut down with respect to star-forming activity – a status scientists refer to as “red and dead.” These galaxies are thought to be low on cold gas, an important raw material for star forming, but a new study in the Monthly Notices of the Royal...

Early Galaxies Formed By Collisions
2014-01-29 14:23:23

Lee Rannals for redOrbit.com - Your Universe Online Astronomers writing in the Astrophysical Journal say that massive galaxies in the early universe were formed through collisions. Scientists studied galaxies that existed when the universe was just between 1 and 2 billion years old. The smallest of these galaxies contain a few million stars, while the largest can contain several hundred billion stars. The first stars in the universe showed up about 200 million years after the Big...

WASHINGTON, Jan. 29, 2014 /PRNewswire-USNewswire/ -- Astronomers using NASA's Hubble Space Telescope and Europe's Herschel Space Observatory have pieced together the evolutionary sequence of compact elliptical galaxies that erupted and burned out early in the history of the universe. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Enabled by Hubble's infrared imaging capabilities, astronomers have assembled for the first time a representative spectroscopic sampling of...

Hubble Reveals First Visual Evidence Of Milky Way's Formative Years
2013-11-14 16:35:20

HubbleSite NASA's Hubble Space Telescope has provided the first visual evidence showing how our home galaxy, the Milky Way, assembled itself into the majestic pinwheel of stars we see today. Perusing Hubble's deep-sky surveys, astronomers traced 400 galaxies similar to our Milky Way at various stages of construction over a time span of 11 billion years. "For the first time we have direct images of what the Milky Way looked like in the past," said study co-leader Pieter G. van Dokkum...

Petal-like Shells And Strange Star Clusters

[ 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....

The Virgo Cluster consists of galaxies at a distance of around 59 Mly away in the constellation Virgo. Containing between 1300 to 2000 galaxies the Virgo Cluster is the heart of the Local Supercluster. Its mass is estimated at 1.2 × 1015 M☉ out to 8 degrees of the cluster's center or a radius of about 2.2 Mpc. Most of the brighter galaxies in the cluster were discovered by Charles Messier in the late 1770's and early 1780's, including the giant elliptical Messier 87. Messier...

The Coma Cluster (Abell 1656), along with the Leo Cluster, is one of two major clusters compromising the Coma Supercluster. It contains over 1000 identified galaxies. Most of the galaxies in the center of the Coma Cluster are elliptical galaxies including both dwarf and giant. However the center is dominated by NGC 4874 and NGC 4889, two giant elliptical galaxies. The brightest galaxies are visible, a few degrees north of the galactic pole, with an amateur telescope larger than 20 cm. The...

Spiral Galaxy -- Among the galaxies, there are apparently three main categories, according to their appearance: the disk galaxies (`cosmic frisbies' according to P. Murdin, D. Allen, and D. Malin), consisting of a huge disk of stars and interstellar matter, which may form interesting patterns, the elliptical galaxies (`cosmic footballs') which are uniformly looking, ellipsoidal agglomerations of stars, and the irregular galaxies (`cosmic misfits') which cannot be integrated in this scheme....

Elliptical Galaxy -- In astronomy, one of the main classes of galaxy in the Hubble classification and characterized by a featureless elliptical profile. Unlike spiral galaxies, elliptical galaxies have very little gas or dust and no stars have recently formed within them. They range greatly in size from giant ellipticals, which are often found at the centres of clusters of galaxies and may be strong radio sources, to tiny dwarf ellipticals, containing about a million stars, which are...

Seyfert's Sextet -- Seyfert's Sextet is a group of galaxies in which gravitational forces are exerted between its members. The galaxies are so tightly packed together that gravitational forces are beginning to rip stars from them and distort their shapes. Those same gravitational forces eventually could bring the galaxies together to form one large galaxy. The name of this grouping, Seyfert's Sextet, implies that six galaxies are participating in the action. But only four galaxies are...
