Interesting astronomy, but headline sounds like a title to a bad Horror comedy movie. :)

Elvis has just left the solar system.

And here I got all excited thinking this was about
Barbara Streisand!

Phoooo!

[neutrino]

Certainly worth a bump!

This is going to be an interesting thread..

Surprising Activity from a Dead Star

Those black holes are so wacky.....nothing they do will ever suprise me!

But Spitzer has super-sensitive infrared eyes

"“Our data show that the presence of an accretion disk and an intense gravitational field may be all we need to form and fuel a compact jet,” Migliari said. '

Such an optimistic can do attitude!!! she/he sounds like he has an accretion disk and intense gravitational field lying around in the back yard.

[tet68]

I've got an accretion disk accumulating around my middle which seems to be creating an intense gravitational field,
although the compact jets are only intermittant at this time.

[sit-rep]

But Spitzer has super-sensitive infrared eyes that can detect jets such as this one, located almost 10,000 light years away in the constellation Orion, in minutes.

Imma dummy with this stuff, but I am also amazed so I'd like to ask... If it takes minutes to get a picture per se, is that picture from 10,000 years ago??

My first thought when reading that title was "Cary Grant is STILL hot after all these years!"

"I've got an accretion disk accumulating around my middle which seems to be creating an intense gravitational field, although the compact jets are only intermittant at this time."

Yeah, I had one of those accretion disks on my left hand ring finger too. It was definitely accompanied by an intense gravitational field. And it's now jetting a significant amount once a month and is expected to continue for the next 10 years. But I'm free of both the disk and the gravitational field, now. Just wish the jets would stop.

Jets from a black holes and dead stars.>>>>>>>>>>>

Perhaps as every star increases its mass, it must have a pressure relieve valve which prevents nuclear fission?

Without the jets would there in fact be a reality rip, a complete rip in the space time continuum?

The more interesting question is why and how does this energy/matter escape when all else is basically sucked in. I did not know the jets contained solid matter, and thought they were radiation plumes, largely consisting of X-rays, and radio waves.

And then there's Rock Hudson. Now that was some surprising activity. He really was acting.

"Perhaps as every star increases its mass, it must have a pressure relieve valve which prevents nuclear fission?"

Maybe, this is best illustrated by Ike and Tina Turner. A black hole can only apply so much pressure before something has to leave.

Yes... the light that left there 10,000 years ago is just getting to Earth today, so we're seeing what it looked like 10,000 years ago. To see what it looks like right now, you'll have to wait until the year 12006.
