simulation of the gas cloud G2's encounter with the supermassive black hole Sgr A*
2014-04-06 06:02:32

Megan Fellman, Northwestern University Gas cloud’s fate could reveal information on growth of supermassive black holes Right now a doomed gas cloud is edging ever closer to the supermassive black hole at the center of our Milky Way galaxy. These black holes feed on gas and dust all the time, but astronomers rarely get to see mealtime in action. Northwestern University’s Daryl Haggard has been closely watching the little cloud, called G2, and the black hole, called Sgr A*, as part...

[ Watch the Video: Time-Lapse of Supermassive Black Hole Sagittarius A* ] April Flowers for redOrbit.com - Your Universe Online During the last few hundred years, the dim region very close to the supermassive black hole near the center of the Milky Way has flared up with at least two luminous outbursts, according to a team of researchers using NASA's Chandra X-ray Observatory. A new study of rapid variations in the X-ray emissions from gas clouds surrounding Sagittarius A* (Sgr A*) -...

Odd Magnetar Has A Very Strong Magnetic Field
2013-08-15 04:36:30

redOrbit Staff & Wire Reports - Your Universe Online An odd type of neutron star located approximately 6,500 light years from Earth has one of the strongest magnetic fields in the universe – despite previous suggestions it possessed an unusually low magnetic field. Using the European Space Agency’s (ESA) XMM-Newton space telescope, a team of astronomers studied the object, a magnetar known as SGR 0418+5729 (SGR 0418). This dense and compact object, which is the dead core of a...

Highly Magnetized Pulsar At Galactic Center
2013-08-14 12:20:25

John P. Millis, PhD for redOrbit.com - Your Universe Online At the center of the Milky Way lurks a supermassive black hole known as Sagittarius A*, with some four million times the mass of our Sun. More than any single object, it has the greatest impact on the formation, evolution and fate of our galaxy. However, probing this massive object is difficult. Due to the nature of black holes, most of what we learn about their existence is derived by observing their influence on other nearby...

Bursts Of Cosmic Radio Waves May Be From The Beginning Of The Universe
2013-07-05 05:13:51

[ Watch the Video: A Population of Fast Radio Bursts at Cosmological Distances ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers writing in the journal Science say they recently discovered mysterious bursts of radio waves originating from billions of light-years away. The scientists have already ruled out the possibility the bursts came from terrestrial sources. Based on the brightness and distance of the four radio waves, the researchers conclude they come from a...

NuSTAR Observatory Busy High Energy Events
2013-06-18 11:08:53

Brett Smith for redOrbit.com - Your Universe Online NASA´s NuSTAR orbiting observatory is designed to investigate high-energy events throughout the universe, and the cosmos has been keeping it busy in recent months, producing one event after another. In early April, the galaxy Markarian 421 produced a high-energy event that increased its brightness by more than 50 times its usual level. Markarian 421 is known as a blazer, a unique class of galaxies with supermassive "feeding" black...

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...

WASHINGTON, May 29, 2013 /PRNewswire-USNewswire/ -- Astronomers using NASA's Swift X-ray Telescope have observed a spinning neutron star suddenly slowing down, yielding clues they can use to understand these extremely dense objects. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) A neutron star is the crushed core of a massive star that ran out of fuel, collapsed under its own weight, and exploded as a supernova. A neutron star can spin as fast as 43,000 times per minute and...

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,...

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...

Magnetar -- A magnetar is a neutron star with a strong magnetic field. The theory around these objects was formulated by Robert Duncan and Christopher Thompson. When in a supernova a star collapses to a neutron star, its magnetic field increases dramatically in strength. Duncan and Thompson calculated that the magnetic field of a neutron star, normally an already enormous 1012 tesla could under certain circumstances grow even larger, to about 1015 tesla. Such a highly magnetic neutron...
