NASA report Receiving a Radio Signal Every 22-Minutes for 35 Years

Since 1988, this mysterious radio signal has arrived every 22 minutes.
Astronomers have detected a weird heart-shaped radio signal from space. It's a fast radio burst (FRB) whose origin is one of the biggest unsolved problems in astronomy. The signal is unusually long: about 3 seconds, and has bursts of high-intensity radiation every 0.2 milliseconds. The 17th episode of the Sunday Discovery Series explains this discovery and the mystery of the Fast Radio Bursts.
For over 30 years, an enigmatic interstellar radio signal has been captivating the cosmos, blinking on and off every 22 minutes. The celestial dance of lights has puzzled scientists and stargazers, leaving them intrigued by the cosmic puzzle that unfolds in the vast expanse of space. With each rhythmic blink, the mystery deepens, and the allure of the unknown beckons us to explore the secrets of this enduring cosmic phenomenon.

#thecosmosnews 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.

Neutron 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 Nature.

“This remarkable object challenges our understanding of neutron stars and magnetars, which are some of the most exotic and extreme objects in the Universe,” said Natasha Hurley-Walker, an astronomer at Curtin University’s International Centre for Radio Astronomy Research and the study’s lead author, in an ICRAR release.

Magnetars are responsible for plenty of the fast radio bursts (FRBs) astronomers witness emanating throughout the cosmos, even from within our own galaxy. But long period radio bursts (or ultra-long period bursts, in the parlance of the researchers) are less common.

The ultra-long period magnetar is named GPM J1839-10, and was first spotted using the Murchison Widefield Array, a radio telescope array located in remote Western Australia. The magnetar’s bursts last up to five minutes long and have been repeating since at least 1988, according to radio archives searched by the team.

Key High lights :

The signal's remarkable stability since 1988 suggests that if it is a neutron star, it is unlike any previously observed, leaving astronomers puzzled about its origin.
🌀
Astronomers are baffled by a radio signal from a neutron star that has maintained its rotation period with remarkable stability over the past 35 years, defying expectations of slowing down.
🤔
Astronomers are baffled by a radio signal that has been received every 22 minutes for 35 years, and its origin remains a mystery.
🔭
The 22-minute radio signal from the neutron star exhibits fluctuations in its polarisation axis, changing by 90 degrees and then returning to its original axis.
⏰
The spin rate of the signal is significantly slower than typical pulsars, spinning once every 1318 seconds, over a thousand times slower, challenging the understanding of pulsar behavior.
🌟
One possible explanation is that the neutron star is actually a magnetar with an incredibly strong magnetic field, leading to cataclysmic events called "starquakes" that release energy as light.
🤔
The lack of x-ray emissions and the prolonged duration of the signal make it incomprehensible that it could be attributed to a magnetar, leaving astronomers searching for alternative explanations.
🌌
The 22-minute signal challenges our current understanding of neutron stars and could lead to a revolution in our understanding of the universe.
