Astronomers from the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav) and CSIRO have just observed bizarre, never-seen-before behavior from a radio-loud magnetar—a rare type of neutron star and one of the strongest magnets in the universe.

An image shows a newly discovered magnetar that spins unbelievably quickly through the Milky Way. (Image: © X-ray: NASA/CXC/Univ. of West Virginia/H. Blumer; Infrared (Spitzer and Wise): NASA/JPL-CalTech/Spitzer) A rapidly twirling, ultramagnetic, 500-year-old baby neutron star has been spotted zipping at never-before-seen speeds through the Milky Way. The flickering X-rays and radio waves of […]

Artist’s depiction of a magnetar. Credit: ESO/L. Calçada Astronomers have recently found the fastest spinning and possibly the youngest magnetar known. This object, known as J1818.0-1607, is located about 21,000 light years away in the Milky Way galaxy. Magnetars are a special class of neutron stars that possess extremely powerful magnetic fields.

A neutron star (left) and its massive, companion star (right). The research team suggests that the neutron star at the heart of LS 5039 has an ultra-strong magnetic field, and is arguably a magnetar. The field accelerates high-energy particles inside the bow-shaped region, thereby emitting gamma-rays that characterize the gamma-ray […]

Parkes UWL observations of Swift J1818.0−1607. Credit: Lower et al., 2020.   ENLARGE Using the Parkes radio telescope, astronomers have investigated a radio-loud magnetar known as Swift J1818.0−1607. Results of these observations, providing more insights into the properties of this magnetar, unveiling its highly active and dynamic magnetosphere. The findings are […]

On May 24, four European telescopes took part in the global effort to understand mysterious cosmic flashes. The telescopes captured flashes of radio waves from an extreme, magnetised star in our galaxy. All are shown in this illustration.

Magnetar-Powered Kilonova Blast. Credit: NASA, ESA, and D. Player (STScI)   ANIMATION Neutron-Star Collision Releases Puzzling Burst of Infrared Light In our infinite universe, stars can go bump in the night. When this happens between a pair of burned-out, crushed stars called neutron stars, the resulting fireworks show, called a kilonova, […]

A powerful X-ray burst erupts from a magnetar – a supermagnetized version of a stellar remnant known as a neutron star – in this illustration. A radio burst detected April 28 occurred during a flare-up like this on a magnetar called SGR 1935. Credit: NASA’s Goddard Space Flight Center/Chris Smith […]
