Astronomers have discovered an activity cycle in another fast radio burst, potentially unearthing a significant clue about these mysterious deep-space phenomena.
An artist's impression of a fast radio burst (FRB) reaching Earth, with colors signifying different wavelengths.
Fast radio bursts, or FRBs, are extragalactic flashes of light that pack a serious wallop, unleashing in a few milliseconds as much energy as Earth's sun does in a century. Scientists first spotted an FRB in 2007, and the cause of these eruptions remains elusive nearly a decade and a half later; potential explanations range from merging superdense neutron stars to advanced alien civilizations.
More than 100 FRBs have been discovered to date, and most of them are one-offs, flaring up just a single time (as far as we know). In January of this year, astronomers reported that one member of the "repeater" class, called FRB 180916.J0158+65, appears to exhibit a 16-day activity cycle: It fires off bursts for a four-day stretch, goes quiet for 12 days and then starts all over again.
The FRB 180916 was the first known to erupt in such a periodic way. And now scientists have spotted another.
Researchers monitored the known repeater FRB 121102 with the Lovell Telescope, a 250-foot-wide (76 meters) radio dish at Jodrell Bank Observatory in England, over the course of five years. They found strong indications of a 157-day activity cycle; 121102 seems to flare up for 90 days and then go silent for 67, the team reported in a new study.

“People of Earth, your attention please.
“The outlying regions of the Galaxy require the building of a hyperspatial express route through your star system, and regrettably your planet is one of those scheduled for demolition. The process will take slightly less that two of your Earth minutes. Thank you.”
“There’s no point in acting all surprised about it. All the planning charts and demolition orders have been on display in your local planning department on Alpha Centauri for fifty of your Earth years, so you’ve had plenty of time to lodge any formal complaint and it’s far too late to start making a fuss about it now.”

I’m sorry, but if you can’t be bothered to take an interest in local affairs, that’s your own lookout.’
An interstellar light house? Nuetron stars ahead mate.

Came a voice from the sky on that magical night
And in the colors of a thousand sunsets
They traveled to the world on a shivering light"

Maybe there’s a planet that has a period of 157 days and they are sending out an SOS...................
Racist,Racist,Racist,
Could it be a Pulsar? There is one in the Crab Nebula that is very powerful. The Earth rotates on its axis once in 24 hours. The Sun rotates once in 26 days. The Pulsar rotates
once in 33 milliseconds. Check it out!
It is only 5,000 light years distance from Earth...
I’m thinking a planet or companion star that has a period of 157 days around it’s primary........................
What does it profit a man to gain the whole world
and “bogey” the last hole?
