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...

It’s not a secret that Bitcoin has some major security flaws when incorporated with unexperienced service providers. Irving, TX (PRWEB) April 24, 2014 Methud (Method, Inc.) has finally finished their OpenStack-based bitcoin mining cloud, set to launch fully on May 1st 2014. Methud is currently taking pre-orders on mining contracts, powered by their ultra-secure cloud, featuring military-grade encryption and other major security upgrades. The Bitcoin industry has had it’s fair share of...

Gum 41: A Study In Scarlet
2014-04-16 10:21:53

ESO [ Watch The Video: Zooming In On The Star Formation Region Gum 41 ] This area of the southern sky, in the constellation of Centaurus (The Centaur), is home to many bright nebulae, each associated with hot newborn stars that formed out of the clouds of hydrogen gas. The intense radiation from the stellar newborns excites the remaining hydrogen around them, making the gas glow in the distinctive shade of red typical of star-forming regions. Another famous example of this phenomenon...

Celestial Diamond Ring Created By Chance Meeting

[ Watch The Video: Zooming In On The Planetary Nebula Abell 33 ] ESO Astronomers using ESO’s Very Large Telescope in Chile have captured this eye-catching image of planetary nebula PN A66 33 — usually known as Abell 33. Created when an aging star blew off its outer layers, this beautiful blue bubble is, by chance, aligned with a foreground star, and bears an uncanny resemblance to a diamond engagement ring. This cosmic gem is unusually symmetric, appearing to be almost circular...

Monkey Head Nebula

NASA/ESA Hubble Space Telescope To celebrate its 24th year in orbit, the NASA/ESA Hubble Space Telescope has released a beautiful new image of part of NGC 2174, also known as the Monkey Head Nebula. This colorful region is filled with young stars embedded within bright wisps of cosmic gas and dust. NGC 2174 lies about 6400 light-years away in the constellation of Orion (The Hunter). Hubble previously viewed this part of the sky back in 2001, creating a stunning image released in 2011,...

WASHINGTON, March 17, 2014 /PRNewswire-USNewswire/ -- In celebration of the 24th anniversary of the launch of NASA's Hubble Space Telescope, astronomers have captured infrared-light images of a churning region of star birth 6,400 light-years away. http://photos.prnewswire.com/prnvar/20081007/38461LOGO The collection of images reveals a shadowy, dense knot of gas and dust sharply contrasted against a backdrop of brilliant glowing gas in the Monkey Head Nebula (also known as NGC 2174...

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...

Snake Nebula
2014-02-26 12:49:25

[ Watch the Video: Birth Of A Star A Family Affair ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers using the Smithsonian's Submillimeter Array (SMA) telescope have imaged the most detailed look yet of stellar nurseries within the Snake nebula. The Snake nebula is about 11,700 light-years away from Earth towards the direction of the constellation Ophiuchus. The astronomers chose this nebula because it shows the potential to form many massive stars. "To learn how...

Supernova Remnant -- A supernova remnant (SNR) is made up of the materials left behind by the gigantic explosion of a star in a supernova. There are two possible routes to this end: either a massive star may cease to generate fusion energy in its core, and collapse inward under the force of its own gravity, or a white dwarf star may accumulate material from a companion star until it reaches a critical mass and undergoes a similar collapse. In either case, the resulting supernova...

Star -- A star is a self-gravitating sphere of plasma in hydrostatic equilibrium that generates energy in its interior through the process of nuclear fusion. Energy from this process radiates into space as electromagnetic radiation and neutrinos. Star formation and evolution As learned by star formation astronomers, stars are born in molecular clouds, regions of higher density of matter, and form by gravitational instability inside those clouds. High mass stars illuminate powerfully...

Reflection Nebula -- In astronomy, reflection nebulae are clouds of dust which are simply reflecting the light of a nearby star or stars. The nearby star or stars are not hot enough to cause ionization in the gas of the nebula like in emission nebulae but are bright enough to give sufficient scattering to make the dust visible. The distiction between these two types of nebulae was done by Hubble in 1922. They are usually blue because the scattering is more efficient for blue light...

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...

Nebula -- in astronomy, observed manifestation of a collection of highly rarefied gas and dust in interstellar space. Prior to the 1960s this term was also applied to bodies later discovered to be galaxies, e.g., the so-called Great Nebula in the constellation Andromeda. In 1864, William Huggins confirmed William Herschel's conclusion that nebulae are not swarms of stars by determining that the spectra of nebulae are made of bright lines characteristic of radiating gases. Diffuse...
