# Unraveling the Mysteries of the Unusual Magnetar
Written on
Chapter 1: Understanding Magnetars
To comprehend the latest cosmic enigma, we first need to define what a magnetar is. Magnetars are a specific type of neutron star, formed from the remnants of massive stars following supernova explosions. These celestial bodies are incredibly dense; just a teaspoon of their material could weigh billions of tons. What distinguishes magnetars from other neutron stars is their exceptionally strong magnetic fields.
Due to these extreme magnetic fields, magnetars exhibit fascinating and energetic phenomena. They often emit bursts of X-rays and gamma rays, detectable from our planet. Additionally, they emit radio waves that pulse in a steady, mysterious pattern, typically repeating every few seconds or minutes.
Normally, these radio pulses fade as the magnetar’s rotation slows, eventually reaching a theoretical “death line” where the magnetic field weakens, stopping high-energy emissions. However, the newly discovered magnetar continues to emit a steady, radiant glow beyond this limit, astonishing researchers who study this already rare category of cosmic objects.
This remarkable object challenges our understanding of neutron stars and magnetars, which are some of the most exotic and extreme objects in the Universe.

Section 1.1: Discovery of GPM J1839–10
The magnetar, known as GPM J1839–10, is located 15,000 light years from Earth and was first detected by the Murchison Widefield Array, a radio telescope array in Western Australia. Researchers discovered that the magnetar's bursts, which can last up to five minutes, have been occurring since at least 1988, based on radio archive searches.
This observation was groundbreaking. While typical radio-emitting magnetars pulse every few seconds or minutes, this one operates on a unique 22-minute cycle, setting a new record for the longest-period magnetar ever identified. This unusual cycle suggests that the magnetar spins exceedingly slowly, well beyond the death line.
Section 1.2: Collaborative Research Efforts
Following the groundbreaking discovery by researchers at Curtin University, GPM J1839–10 is now recognized as only the second magnetar of its kind identified. A paper detailing its unique characteristics was published in Nature in January 2022, where researchers struggled to explain this enigmatic transient object that intermittently emits powerful energy beams three times an hour.
To better understand this mysterious magnetar, the research team conducted an extensive analysis using observations from six different radio telescopes globally, along with archival data dating back to 1988. They made an astonishing finding: the same object had appeared in the oldest dataset, pulsating with nearly the same 22-minute interval, remaining remarkably consistent over the past 33 years.
Chapter 2: Theoretical Implications
Researchers speculate that the unusual characteristics of this celestial object, including its slow rotation, prolonged pulse period, and persistent radio emissions, challenge all existing models currently applied. They propose that it might be a white dwarf—another type of stellar remnant—larger than a magnetar and rotating at a slower rate. However, the team emphasized that the radio emissions from this object are at least 1,000 times brighter than the brightest white dwarf ever recorded. Clearly, this matter is still open for exploration.
