John P. Millis, Ph.D. for redOrbit.com - Your Universe Online While images of the Milky Way or Andromeda galaxies may dominate our mind’s image of what a galaxy looks like, the fact is that the largest objects in the Universe come in all shapes and sizes. In fact, most galaxies in the cosmos are known as dwarf galaxies. These systems are, as the name might suggest, smaller versions of the elliptical, spiral, and irregular galaxies that usually spring to mind. In many cases, these...

star formation region Gum 15
2014-07-02 10:48:50

European Southern Observatory The little-known cloud of cosmic gas and dust called Gum 15 is the birthplace and home of hot young stars. Beautiful and deadly, these stars mold the appearance of their mother nebula and, as they progress into adulthood, will eventually also be the death of her. This image was taken as part of the ESO Cosmic Gems program [1] using the Wide Field Imager on the MPG/ESO 2.2-meter telescope at the La Silla Observatory in Chile. It shows Gum 15, located in the...

Serpens Cloud Core Hatches New Stars

By Whitney Clavin, NASA's Jet Propulsion Laboratory Stars that are just beginning to coalesce out of cool swaths of dust and gas are showcased in this image from NASA's Spitzer Space Telescope and the Two Micron All Sky Survey (2MASS). Infrared light has been assigned colors we see with our eyes, revealing young stars in orange and yellow, and a central parcel of gas in blue. This area is hidden in visible-light views, but infrared light can travel through the dust, offering a peek inside...

New Insight Into Formation Of Star Clusters Provided By NASA's Chandra X-ray Observatory
2014-05-16 03:44:41

[ Watch The Video: A Tour Of The Flame Nebula ] Harvard-Smithsonian Center for Astrophysics Stars are often born in clusters, in giant clouds of gas and dust. Astronomers have studied two star clusters using NASA's Chandra X-ray Observatory and infrared telescopes and the results show that the simplest ideas for the birth of these clusters cannot work. This composite image shows one of the clusters, NGC 2024, which is found in the center of the so-called Flame Nebula about 1,400...

Star Cluster Study Inspires New Ideas On How Sun-Like Stars Form
2014-05-08 10:15:43

Brett Smith for redOrbit.com - Your Universe Online The prevailing theory on star cluster formation states that gravity causes a giant cloud of gas and dust to condense to concentrations that trigger the ignition of stars at the center of the cloud. However, according to a new study based on data from NASA's Chandra X-ray Observatory and infrared telescopes, some of the oldest stars in known clusters sit on the exterior of their groups. The study researchers focused on two clusters...

WASHINGTON, May 7, 2014 /PRNewswire-USNewswire/ -- Using data from NASA's Chandra X-ray Observatory and infrared telescopes, astronomers have made an important advance in the understanding of how clusters of stars come into being. http://photos.prnewswire.com/prnvar/20081007/38461LOGO The data show early notions of how star clusters are formed cannot be correct. The simplest idea is stars form into clusters when a giant cloud of gas and dust condenses. The center of the cloud pulls...

Protostars In Orion Nebula Doomed By Larger Stars
2014-03-11 06:11:18

Lee Rannals for redOrbit.com - Your Universe Online Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) found that some protostars in the Orion Nebula are doomed from the beginning. The Orion Nebula has hundreds of young stars, or protostars, and even some “proplyds,” which are stars that are even younger than protostars. Astronomers have discovered that some of these young stars will have their planet-forming dust and gas blasted away from another star when...

Crab Nebula Surprises Astronomers With Noble Gas Molecules
2013-12-13 04:31:42

[ Watch the Video: Supernova Remnant Shows Signs Of Noble Gas ] redOrbit Staff & Wire Reports - Your Universe Online Astronomers from the UK have discovered argon hydride within the Crab Nebula, marking the first time that noble gas molecules have been detected in space, according to research appearing in Friday’s edition of the journal Science. As part of their study, Mike Barlow of the University College London Department of Physics and Astronomy and his colleagues used the...

Ghostly Trio Imaged Using NASA's Spitzer Space Telescope
2013-10-29 10:12:36

NASA's Jet Propulsion Laboratory In the spirit of Halloween, scientists are releasing a trio of stellar ghosts caught in infrared light by NASA's Spitzer Space Telescope. All three spooky structures, called planetary nebulas, are in fact material ejected from dying stars. As death beckoned, the stars' wispy bits and pieces were blown into outer space. "Some might call the images haunting," said Joseph Hora of the Harvard-Smithsonian Center for Astrophysics, Cambridge, Mass., principal...

The NGC 5866, located in the Draco constellation, is named after the galaxy with the highest magnitude however some catalogs list NGC 5907 as the brightest member. The M51 Group and the M101 Group are NGC 5866 closest neighbor. The distances between these groups are similar which suggest the three groups are part of a single large, loose, elongated group. However, most identification methods consider them separate.

The M101 Group, one of many in the Virgo Supercluster, is located in Ursa Major and named after the brightest galaxy in the group, the Pinwheel Galaxy (M101). The group is composed mostly of members that are companions of the Pinwheel Galaxy. The M51 Group and the NGC 5866 Group are M101's closest neighbor. The distances between these groups are similar which suggest the three groups are part of a single large, loose, elongated group. However, most identification methods consider them...

The M51 Group, located in Canes Venatici, is named after the brightest galaxy in the group, the Whirlpool Galaxy (M51A). The few other notable members include the companion galaxy to the Whirlpool Galaxy (M51B) and the Sunflower Galaxy (M63).

Planetary Nebula -- A planetary nebula is an astronomical object that usually appears nebulous and disk-like in low-resolution observations. Because of this appearance, similar to the appearance of planets in early observations, the "planetary" adjective was attached and has since been retained for historical consistency. According to current observations and models, planetary nebulae in fact have little to do with planets. Instead, as a small star (less than a few times the mass...

Galaxy -- Stars are almost always found in collections called galaxies, together with gas, dust, and large amounts of dark matter detected by its gravitational effects. These are all held together by gravitational attraction and orbit a common centre. There is some evidence that black holes may exist at the centre of some or most galaxies. Galaxies come in three main types: ellipticals, spirals, and irregulars. A slightly more extensive description of galaxy types is given by the Hubble...
