ET Phone Home!......
Is it V-ger?

Cosmic burps?
>The Shadow knows
Da Shaddow Do!
Maybe they're calling Dan home.
guess I already know the subject of tonight's Coast to Coast
As per last night's discussion.
Now what's this I read about black holes emitting radio waves? I thought nothing could escape those monsters.
powerful burst of intermittent radio waves emanating from the direction of the center of our galaxy.
The timing's right. I hear alien sirens singing...
I think it's more technically correct to say that black holes' properties cause other things near them to emit radiation, rather than it coming from the black hole itself.
Can't they just call it Fred?
Paging Jody Foster,
Paging Jody Foster, please pick up the white courtsey phone!

Must have a hell of a good radio in there.

A mystery object near the centre of our galaxy is sending out powerful pulses of radio waves. It is unlike any known source.
A team of astronomers led by Scott Hyman of Sweet Briar College, Virginia, US, detected the mysterious source using the Very Large Array radio telescope in New Mexico.
The pulses are coming from a spot just to one side of the galactic centre. Each pulse lasts about 10 minutes, and they repeat regularly every 77 minutes. If, as the researchers think, the source is near the centre of the Milky Way, it would be one of the most powerful emitters in the galaxy. The shape and timing of the pulses rules out most known sources, such as radio pulsars.
The object could be a magnetar - a neutron star with an ultra-strong magnetic field. "Magnetars store plenty of energy to power the observed outbursts," says Hyman. Or it may be something entirely new. To find out more, the team is studying it using the Green Bank radio telescope in West Virginia, and hopes to use NASA's Chandra space telescope to see if it is also spitting out X-rays.
