Keppler Telescope Revealed We Have Been Receiving a Radio Signal Every 22-Minutes for 35 Years...

In 2022, astronomers found a strange radio signal coming every 22 minutes using the Murchison Widefield Array and when they checked past records, they saw this signal had been reaching Earth since at least 1988. Usually, these signals come from pulsars, stars that flashlight as they spin. But this time, it was way more stable than any pulsar they knew. What is really behind these weird noises that are terrifying the scientific community? Let us dive into the real truth behind these anomalies that could lead to the first encounter with alien life.

The distant object known as GPM J1839–10, located about 18 thousand light-years away from Earth, transmits signals to us in a rather inconsistent pattern. These signals, or pulses, can last anywhere from a brief 30 seconds to a longer five minutes, and they do not arrive at regular intervals. The gap between the pulses can vary by over six minutes, which makes it difficult to predict when the next pulse will come. Despite this irregularity, the object is believed to be a neutron star, a type of star known for its complex behavior, where multiple factors could be influencing how and when these pulses are sent to us.

For over three decades, astronomers have been sifting through data to understand the behavior of this source. They have been able to track its rotation, finding that it spins around completely every 21 minutes and 58 seconds. What is surprising is that, contrary to what is typical for neutron stars, this rotation rate has not changed significantly over the years. Neutron stars usually lose energy as they emit radiation, which should slow down their rotation over time. However, GPM J1839–10 has shown remarkable consistency in its rotational period, with any possible decrease in speed being so minor—less than 0.28 milliseconds—that it's almost negligible.
