The Largest Magnetic Fields In The Universe
2013-07-29 04:11:34

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Gamma-ray bursts (GRBs) are thought to be the most powerful, energetic events in the Universe. They can release as much energy in one second as an entire galaxy expels in an entire year. But while astronomers have some solid theories on what drives these events, many of the details are still widely debated. One of the complicating matters comes from the fact GRBs appear to fall into two separate classes: long and short burst...

I Love Q Formula Insights Into Universe
2013-07-26 11:51:21

April Flowers for redOrbit.com - Your Universe Online Without understanding the internal structure in detail, it is still possible for scientists to learn a tremendous amount about neutron stars and quark stars, according to a new study from researchers at Montana State University. "The stars could be the softest or the hardest in their kind, and it wouldn't matter," said Nico Yunes, assistant professor in MSU's Department of Physics. Yunes and his colleague, postdoctoral scholar Kent...

Gold Created By Colliding Stars
2013-07-18 04:18:47

[ Watch the Video: Merging Neutron Stars ] redOrbit Staff & Wire Reports - Your Universe Online A gamma-ray burst (GRB) created by the collision of two neutron stars has given researchers new insight into how gold, one of the rarest elements on Earth, and in the entire universe, is formed. Lead author Edo Berger of the Harvard-Smithsonian Center for Astrophysics (CfA) and his colleagues explain that unlike elements such as carbon or iron, gold cannot be created inside of a star....

Monstrous Stellar Collisions Not Expected To Occur Anytime Soon
2013-07-11 14:32:31

Lee Rannals for redOrbit.com - Your Universe Online Astrophysicists from the Astronomical Observatory of the Faculty of Physics at the University of Warsaw say the next collision of monstrous stars will not occur until billions of years from now. Three years ago, scientists discovered that the Magellanic Clouds host gigantic stars with between 200 and 300 times the solar mass  of our own Sun. Before then, astronomers believed that the biggest stars in the Universe did not...

Astronomers May Have Witnessed A Collapsing Neutron Star
2013-07-05 04:16:37

John P. Millis, PhD for redOrbit.com - Your Universe Online Radio observatories have recently noticed bursts of radio light emerging in the night sky. The intense flashes exist for only a moment then disappear and do not seem to repeat. These so called 'blitzars' are a mystery, but researchers Heino Falcke (Max-Plank Institute for radio astronomy) and Luciano Rezzolla (Albert-Einstein Institute in Potsdam) have suggested we may be witnessing the death-cry of a supermassive pulsar...

Computer Simulations Shed New Light On Neutron Star Formation
2013-06-28 04:30:08

redOrbit Staff & Wire Reports - Your Universe Online Researchers from the Max Planck Institute for Astrophysics (MPA) have, for the first time, created three-dimensional computer models in order to study the formation of neutron stars at the center of collapsing stars, officials from the German research center announced earlier this week. By creating what they call the most expensive and elaborate computer simulations of the process to date, the team of investigators confirmed,...

Evidence Of New Phase In Neutron Stars Discovered
2013-06-14 13:48:03

Lee Rannals for redOrbit.com — Your Universe Online University of Alicante researchers have discovered the first evidence of a new phase in neutron stars. The scientists wrote in the journal Nature Physics that they have detected what may be the first observational evidence of existence of a new exotic phase of matter in what is known as the "inner crust" of neutron stars, or pulsars. "This may be the first observational evidence of existence of the phase of nuclear...

Anti Glitch Observed In Pulsar Star

John P. Millis, PhD for redOrbit.com — Your Universe Online When a massive star — one several times larger than our Sun — consumes all of the fusible matter in its core, it begins to implode in a brilliant supernova. Driven by gravitational collapse, the core of the star will form either a neutron star or a black hole, depending upon its mass. While not quite as exotic or dense as a black hole, a neutron star is still an amazing object and provides a useful laboratory...

NASA X-Ray Observatory Reveals Magnetars More Common Than Thought
2013-05-24 14:42:15

Lee Rannals for redOrbit.com — Your Universe Online NASA's Chandra X-ray Observatory has revealed that some of the most extreme objects in the universe may be more common than previously thought. Magnetars are the dense remains of dead stars that erupt sporadically with bursts of high-energy radiation. When a massive star runs out of fuel its core collapses to form a neutron star. Most neutron stars spin rapidly, but a small fraction have a relatively low spin rate while also...

X-Ray Astronomy -- Although the more energetic X-rays (E > 30 keV) can penetrate the air at least for distances of a few meters (they would never have been detected and medical X-ray machines would not work if this was not the case) the Earth's atmosphere is thick enough that virtually none are able to penetrate from outer space all the way to the Earth's surface. X-rays in the 0.5 - 5 keV range, where most celestial sources give off the bulk of their energy, can be stopped by a few...

X-ray Pulsar -- This dramatic artist's vision shows a city-sized neutron star centered in a disk of hot plasma drawn from its enfeebled red companion star. Ravenously accreting material from the disk, the neutron star spins faster and faster emitting powerful particle beams and pulses of X-rays as it rotates 400 times a second. Could such a bizarre and inhospitable star system really exist in our Universe? Based on data from the orbiting Rossi X-Ray Timing Explorer (RXTE) satellite,...

Supernova -- A supernova is a star that increases its brightness drastically within a matter of days, making it appear as if a "new" star was born (hence "nova"). The "super" prefix distinguishes it from a mere nova, which also involves a star increasing in brightness, though to a lesser extent and through a much different mechanism. Astronomers have classified supernovae in several classes, according to the lines of different elements that appear in their spectra. The first...

Strange Matter -- Strange matter (also known as quark matter) is an ultra-dense phase of matter that is theorized to form inside particularly massive neutron stars (which are then known as "strange stars" or "quark stars"). It's theorized that when neutronium is put under sufficient pressure due to the gravitation of a large neutron star, the individual neutrons break down and their constituent quarks form strange matter. Strange matter is composed of strange quarks bound to each...

Pulsar -- A pulsar, which originally stood for pulsating radio source, is a rapidly rotating neutron star, whose electromagnetic radiation is observed in regularly spaced interval, or pulses. Pulsars are closely related to magnetars, the main difference being the strenght of the object's magnetic field. History Pulsars were discovered by Jocelyn Bell and Antony Hewish in 1967 while they were using a radio array to study the scintillation of quasars. They found a very regular...
