I don't think the title is really accurate- it doesn't emit radio signals every 8 minutes, it emits constantly, but emits along an axis that periodically aligns with our viewing cone.
I didn't know that there was a whole slew of these red and white dwarfs orbiting other stars, which I think must make it extra unlikely for there to be habitable planets in the same system, the process of one star capturing another is going to realy wreck havock with any original planets,
and any surviving lifeform to get past the am radio phase of technological development
thats! GPM J071507−114153, "the pulse on your dial" brought to by astrophyisal phenominon, every 8 min, for eterinty
Yes but repeated evenly spaced pulses are special and limited to a special subset of stars caller pulsars. The sun is mostly wideband radio noise where the article is talking about distinct regular pulses which are rarer.
If you have satellite TV you already have a solar radiotelescope.
Measure the voltage on the AGC line in the tuner and you'll see a peak as the sun passes the azimuth of the dish. That's it picking up 10GHz solar radiation, and turning its gain down to compensate for the background noise.

Pulsars are usually faster than that I guess.
Nuke them before it's too late!

The signal? "Replace smoke alarm battery"
Then it would be periodic but so long between signals that it would be nearly impossible to determine where it was coming from.
Maybe it is a musical instrument smoke alarm
What's that beep? Eh, we'll figure it in the next galactic epoch, go back to bed.
We are on our way, Carol!
Radio... Live transmission?
I mean, yes. Every star does.

Sorry I was making a dumb joke about a song
You responded to a “joke” but hey this is cool new info for me

I got it! :) There is no Joy in this HN Division.
apparently its a class of objects https://en.wikipedia.org/wiki/Long_period_radio_transient
