Recent observations by NASA’s X-ray telescopes have provided unprecedented insights into fast radio bursts (FRBs), powerful and brief cosmic events that have puzzled astronomers. By studying a fast radio burst from a magnetar within our galaxy, scientists have advanced our understanding of these phenomena, revealing rapid changes in magnetar behavior that could explain how FRBs are generated.

Researchers discovered a universal scaling law in neutron stars, including magnetars, that might explain mysterious Fast Radio Bursts (FRBs). By studying the sub-structure of their radio emissions, they found a commonality in their rotation periods, enhancing our understanding of these celestial phenomena.A universal relation for pulsars, magnetars, and potentially fast radio bursts.An international research team led by Michael Kramer and Kuo Liu from the Max Planck Institute for Radio Astronomy in Bonn, Germany, have…

An unexplainable ultrabright steller object was found, which is reported to be blazing even beyond death. The object is 15000 light-years away from Earth. Researchers believe that it is a shattered part of a giant star, commonly known as a magnetar.According to a Live Science report. it is as small as a city and yet the stellar object may have a huge amount of mass, similar to the sun. It has a magnetic field more than a quadrillion times stronger than Earth's. About stellar objectThe rotating magnetar can spin and…

Astrophysicist Dong Lai theorizes that a quantum electrodynamics (QED) effect called “photon metamorphosis” accounts for unexpected observations of X-ray polarization from a magnetar, a neutron star with an intense magnetic field. Lai’s theory suggests X-ray photons passing through the magnetar’s magnetized atmosphere can temporarily transform into pairs of “virtual” electrons and positrons, leading to differing polarizations for low and high-energy X-rays.A “beautiful effect” predicted by quantum electrodynamics (QED)…

An intensely magnetic neutron star roughly 15,000 light-years from Earth is stumping astronomers with its ultra long periods, unleashing radio waves into the cosmos every 22 minutes.“Dungeons & Dragons is My Nerdy Obsession” | First FandomsNeutron stars with intense magnetic fields are called magnetars. Now, 22-minute periods may sound relatively frequent in Earthly time scales, but most magnetars have periods between a few seconds and a few minutes. The team’s research describing the object was published this week in…

Fast radio bursts are one of the biggest cosmic mysteries of our time. They're extremely powerful but extremely brief explosions of electromagnetic radiation in radio wavelengths, discharging in milliseconds as much energy as 500 million Suns.  For years, scientists puzzled over what could be causing these brief outbursts, detected in galaxies millions to billions of light-years away. Then, in April 2020, we got a really strong lead: a brief, powerful flash of radio waves from something inside the Milky Way – a…
