Supernova Recreation Reveals How Interstellar Magnetic Fields May Have Formed
2014-06-02 10:03:18

Brett Smith for redOrbit.com - Your Universe Online Using a laser beam 60,000 billion times more powerful than a typical laser pointer, researchers have recreated a small-scale supernova and revealed that cosmic turbulence may have boosted magnetic fields to the power seen in interstellar space, according to a new report in the journal Nature Physics. "Magnetic fields are ubiquitous in the universe," said study author Don Lamb, a professor in astronomy and astrophysics at the University...

Complex Outflow Structure Revealed In The Binary UY Aurigae
2014-05-21 03:43:00

National Astronomical Observatory of Japan An international team of astronomers, led by Dr. Tae-Soo Pyo (Subaru Telescope, NAOJ), has revealed a complicated outflow structure in the binary UY Aur (Aurigae). The team observed the binary using the Gemini North"s NIFS (Near-Infrared Integral Field Spectrometer) with the Altair adaptive optics system. The team found that the primary star has a wide, open outflow, while the secondary star has a well-collimated jet. Because many stars form...

Currently those dreams are exploding into reel reality with the launch of an original screenplay into film production that won movie trailer plaudits at the prestigious...

Chandra X-ray Observatory Sees Runaway Pulsar Firing A Record-breaking Jet
2014-02-19 09:27:55

NASA NASA's Chandra X-ray Observatory has seen a fast-moving pulsar escaping from a supernova remnant while spewing out a record-breaking jet – the longest of any object in the Milky Way galaxy -- of high-energy particles. The pulsar, a type of neutron star, is known as IGR J11014-6103. IGR J11014-6103's peculiar behavior can likely be traced back to its birth in the collapse and subsequent explosion of a massive star. Originally discovered with the European Space Agency satellite...

Bipolar Jets Of Gas, Dust Created By Small Planetary Nebulae
2014-02-13 08:01:47

April Flowers for redOrbit.com - Your Universe Online Large stars can end their lives as violently cataclysmic supernovae. Small stars, in contrast, end up as planetary nebulae—colorful, glowing clouds of dust and gas. These nebulae were once thought to be mostly spherical. In the last few decades, however, they have been observed to often emit powerful, bipolar jets of gas and dust. Scientists are unsure how spherical stars evolve to produce highly aspherical planetary nebulae, however....

Massive Star Formation Mystery Solved
2014-01-28 04:04:20

Brett Smith for redOrbit.com - Your Universe Online Enormous young stars, which have over 10 times the mass of the Sun, shine brilliantly in ultraviolet wavelengths, energizing the gas around them, and it has long been a mystery why this superheated gas doesn't explode outwards. According to a new study in The Astrophysical Journal Letters, a group of scientists using the Jansky Very Large Array (VLA), a radio observatory in New Mexico, has validated theories that say as the gas cloud...

massive Star forming cluster discovered

Lee Rannals for redOrbit.com - Your Universe Online Astronomers using the Smithsonian's Submillimeter Array (SMA) have discovered a giant star-forming region. Known as W49A, the region is located 36,000 light-years away from Earth on the opposite side of the Milky Way. Astronomers say the star-forming region shines 100 times brighter than the Orion nebula. In order to view W49A, astronomers had to aim SMA through dusty fog, after which the telescope helped reveal an active site of star...

Tycho Supernova Mach 1000 Shock Wave
2013-11-26 15:49:52

John P. Millis, PhD for redOrbit.com - Your Universe Online Somewhere in the Universe a star or stellar remnant is preparing to explode. Binary white dwarf systems can build up in mass as the compact object accretes mass from its companion. Eventually, the tiny ball of matter will explode in a brilliant event known as a supernova. The blast can glow for weeks or even months before eventually fading. However, the shock wave from the event will travel through the surrounding medium,...

Throes Of Stellar Birth Revealed As Never Before
2013-11-12 04:04:45

April Flowers for redOrbit.com - Your Universe Online The bubbly birth of a bouncing baby star has been revealed by observations from NASA's Spitzer Space Telescope and the newly completed Atacama Large Millimeter/submillimeter Array (ALMA) in Chile. For the well-studied object known as HH 46/47, the observations have revealed the mechanisms of stellar birth as never before seen. HH, or Herbig-Haro, objects form when jets pushed out by newborn stars collide with material surrounding...

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 Formation -- Star formation is the process by which gas in molecular clouds gets transformed into stars. In the current paradigm of star formation, cores of molecular clouds (regions of specially high density) became gravitationally unstable, and start to concentrate. Part of the gravitational energy lost in the process is radiated in the infrared, another part increases the temperature of the core. The accretion of material happen partially though a circumstellar disc. When...

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...
