Latest Magnetar Stories
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.
Astronomers writing in the journal Science say they recently discovered mysterious bursts of radio waves originating from billions of light-years away.
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.
Scientists say 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.
Using data from NASA’s Swift X-ray satellite, researchers have found a new type of pulsar glitch that they've dubbed an "anti-glitch."
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.
One recently discovered star seems to have a split personality, with both a magnetar and pulsar consuming the object.
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...
